摘要：先來講講為啥子，要寫這篇文章因?yàn)榉?wù)器操作系統(tǒng)，軟件版本，以及需求，都千奇百怪。的模塊使用來解析正則表達(dá)式該庫(kù)提供了很多種壓縮和解壓縮的方式，使用對(duì)包的內(nèi)容進(jìn)行。

因?yàn)榉?wù)器操作系統(tǒng)，軟件版本，以及需求，都千奇百怪。網(wǎng)上有很多教程每一種都不一樣！而且按照上面傻瓜式復(fù)制粘貼操作完成安裝的也在少數(shù)(本人用了很多但是沒有一個(gè)傻瓜操作成功的) 基本上都是有些經(jīng)驗(yàn)的遇到安裝錯(cuò)誤之后自行解決了！，所以我這面綜合寫一個(gè)文章（其實(shí)就是閑的）
閑話不多說，開始第一波操作

??毋庸置疑，在服務(wù)器進(jìn)行一系列環(huán)境搭建之前，做好創(chuàng)建一個(gè)快照（就是系統(tǒng)的某一個(gè)時(shí)間點(diǎn)的所有備份，就跟照片一樣，時(shí)間定格某一個(gè)畫面），防止你的系統(tǒng)被你安裝的亂七八糟的！到時(shí)候不好刪，直接回滾磁盤來的方便！

云服務(wù)器( 栗子：阿里云 ）
創(chuàng)建辦法：控制臺(tái)->云服務(wù)器->選中你的實(shí)例->本實(shí)例的磁盤->創(chuàng)建快照 (這里如果你還找不到的話，聽我的話放棄IT吧孩子)

使用辦法：控制臺(tái)->云服務(wù)器->選中你的實(shí)例->本實(shí)例的快照->回滾磁盤（這時(shí)候你的所有配置什么的環(huán)境啊，也都回滾了）

獨(dú)立服務(wù)器
獨(dú)立服務(wù)器，就是指你自己有的硬件服務(wù)器（通俗來講就是，你能看到的實(shí)體的服務(wù)器）
這里不做推薦，因?yàn)槿绻銜?huì)搭建快照軟件的話，這篇文章對(duì)你提升也不大！散了吧
如果你不會(huì)但是想學(xué)習(xí)一下的話，想了解一下的話可以看一下下面的鏈接
《10種linux下磁盤快照方式恢復(fù)系統(tǒng)》

??安裝nginx 之前先確定好自己的服務(wù)器操作系統(tǒng)對(duì)應(yīng)相對(duì)應(yīng)的操作系統(tǒng)來做！

contos（本人用的是新的CentOS 7.4 64，其實(shí)個(gè)人感覺版本什么的安裝程序差別不大）

1）用root用戶 找到你的目錄文件夾（本人推薦用root用戶進(jìn)行安裝，不知道的 "cd ~"）

2）開始安裝依賴(yum不知道是什么命令的，自己百度科普一下yum rpm 編譯安裝)

gcc:nginx編譯依賴gcc環(huán)境
yum install -y gcc-c++ 

  pcre:(Perl Compatible Regular Expressions)是一個(gè)Perl庫(kù)，包括 perl 兼容的正則表達(dá)式庫(kù)。nginx的http模塊使用pcre來解析正則表達(dá)式.
yum install -y pcre pcre-devel 

  zlib：該庫(kù)提供了很多種壓縮和解壓縮的方式，nginx使用zlib對(duì)http包的內(nèi)容進(jìn)行g(shù)zip。
yum install -y zlib zlib-devel 

  openssl:一個(gè)強(qiáng)大的安全套接字層密碼庫(kù)，囊括主要的密碼算法、常用的密鑰和證書封裝管理功能及SSL協(xié)議，并提供豐富的應(yīng)用程序供測(cè)試或其它目的使用。nginx不僅支持http協(xié)議，還支持https（即在ssl協(xié)議上傳輸http）.
yum install -y openssl openssl-devel 

3)下載安裝nginx（我這里是1.12的版本，大家可以自行選擇）

wget http://nginx.org/download/nginx-1.12.0.tar.gz  下載安裝包

tar -zxvf nginx-1.12.0.tar.gz                       解壓安裝包

cd nginx-1.12.0                                     找到解壓  

   接下來是重點(diǎn)的部分
   注：安裝之前需要手動(dòng)創(chuàng)建上面指定的nginx文件夾，即/var/temp、/var/temp/nginx、/var/run/nginx/文件夾，否則啟動(dòng)時(shí)報(bào)錯(cuò)（如果不知道怎么新建文件夾《Linux 學(xué)習(xí)之創(chuàng)建、刪除文件和文件夾命令》，或者用ftp創(chuàng)建也行)
  (為什么要這么做，因?yàn)檫@個(gè)是在網(wǎng)絡(luò)上面比較好的一個(gè)安裝目錄，要不然就用yum安裝了，安裝之后別說nginx配置文件在哪？網(wǎng)站根目錄在哪？如果不知道這些配置文件的用途 推薦你們看《Nginx編譯參數(shù)大全 configure參數(shù)中文詳解》)
./configure 
  --prefix=/usr/local/nginx 
  --pid-path=/var/run/nginx/nginx.pid 
  --lock-path=/var/lock/nginx.lock 
  --error-log-path=/var/log/nginx/error.log 
  --http-log-path=/var/log/nginx/access.log 
  --with-http_gzip_static_module 
  --http-client-body-temp-path=/var/temp/nginx/client 
  --http-proxy-temp-path=/var/temp/nginx/proxy 
  --http-fastcgi-temp-path=/var/temp/nginx/fastcgi 
  --http-uwsgi-temp-path=/var/temp/nginx/uwsgi 
  --http-scgi-temp-path=/var/temp/nginx/scgi  配置命令 （一起復(fù)制）

make && make install 編譯并且編譯安裝

這就基本上可以了使用了

cd /usr/local/nginx/sbin/ 找到執(zhí)行文件地方
./nginx                   啟用nginx
   若報(bào)錯(cuò)：[emerg] open() "/var/run/nginx/nginx.pid" failed (2: No such file or directory)
   需要查看下是不是在 /var/run 文件夾下不存在 nginx 文件夾，不存在則新建
ps -ef | grep nginx 我們可以看一下這個(gè)是否啟動(dòng)成功了


  也就是證明你安裝成功了
  啟動(dòng)成功后訪問你的ip或者域名就能看到

  想要停止就要
cd /usr/local/nginx/sbin && ./nginx -s stop 強(qiáng)行停止
cd /usr/local/nginx/sbin && ./nginx -s quit 完整停止(建議使用)
cd /usr/local/nginx/sbin && ./nginx -s quit && ./nginx 重啟
cd /usr/local/nginx/sbin && ./nginx -s reload 重新加載配置
   但是這樣很麻煩，一般我們都會(huì)用shell做成服務(wù)，如果你嫌麻煩那么可以看一下如何封裝成服務(wù)
service nginx restart 重啟
service nginx stop  停止
service nginx start 啟動(dòng)
   這樣是不是很帥，請(qǐng)看后續(xù)教程《小白系列：如何將軟件裝成service》

寫累了，未完待續(xù)---2018-08-11

??開始安裝php了

contos（本人用的是新的CentOS 7.4 64，其實(shí)個(gè)人感覺版本什么的安裝程序差別不大）

1）回到到你的目錄文件夾（不知道的 "cd ~"）

2）開始安裝一些常用的php庫(kù)

依次執(zhí)行以下命令（常用的庫(kù)，如果有什么要用的沒有安裝的，等安裝完php后自己再獨(dú)立安裝也可以）
yum -y install libmcrypt-devel mhash-devel libxslt-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel 

3)下載并安裝php（我這里是7.1.11的版本，大家可以自行選擇）

wget http://cn2.php.net/distributions/php-7.1.11.tar.gz  下載php官方安裝包(速度還是蠻快的說)

tar -zxvf php-7.1.11.tar.gz                       解壓安裝包

cd php-7.1.11                                     找到解壓  

   開始配置編譯參數(shù)

  ./configure 
   --prefix=/usr/local/php7 
   --with-config-file-path=/usr/local/php7/etc 
   --enable-fpm 
   --with-mcrypt 
   --enable-mbstring 
   --enable-pdo 
   --with-curl 
   --disable-debug  
   --disable-rpath 
   --enable-inline-optimization 
   --with-bz2  
   --with-zlib 
   --enable-sockets 
   --enable-sysvsem 
   --enable-sysvshm 
   --enable-pcntl 
   --enable-mbregex 
   --with-mhash 
   --enable-zip 
   --with-pcre-regex 
   --with-mysqli 
   --with-gd 
   --with-jpeg-dir 
   --with-freetype-dir 
   --enable-calendar  配置命令 （一起復(fù)制）

make && make install 編譯并且編譯安裝(那這個(gè)時(shí)間就比較長(zhǎng)了，我先去吃點(diǎn)東西~)

  直接啟動(dòng)會(huì)報(bào)錯(cuò)，先依次執(zhí)行下面命令，將默認(rèn)的配置文件變成真正的配置文件
cp /root/php-7.1.11/php.ini-production /usr/local/php7/etc/php.ini

cd /usr/local/php7/etc

cp php-fpm.conf.default php-fpm.conf

cd /usr/local/php7/etc/php-fpm.d

cp www.conf.default www.conf  

  需要查看下是不是在 /var/run 文件夾下不存在 php7文件夾，不存在則新建
  使用vim命令對(duì)php-fpm.conf的內(nèi)容進(jìn)行如下修改
cd /usr/local/php7/etc 找到配置文件夾
vim php-fpm.conf 打開后輸入i進(jìn)入編輯模式
pid = /run/php7/php-fpm.pid 
  （大概在17行左右，記住把前面的 ; 去掉,至于為什么在/run/php7/這，因?yàn)楸救讼矚g和nginx保持一致）
  之后按esc，在之后按shift+: 輸入wq回車 （這文檔編輯 就不在這教大家了）


cd /usr/local/php7/sbin && ./php-fpm 啟動(dòng)
  然后查看一下是否啟動(dòng)成功

  圖上就表示啟動(dòng)成功了

  關(guān)閉比較麻煩
kill 進(jìn)程id (注意關(guān)閉之前確認(rèn)這個(gè)ID一定要，別關(guān)錯(cuò)了，【假裝這里有一個(gè)苦笑的表情】)



  那么php就安裝完了如果有人問到，為什么我php -v啥的不好使呢，這個(gè)跟windows一樣,需要放在環(huán)境變量里面，這個(gè)和上個(gè)面的nginx都可以封裝成系統(tǒng)的service，以下mysql也是一樣！這樣啟動(dòng)，和重啟，關(guān)閉啥的就很簡(jiǎn)單了！請(qǐng)看后續(xù)教程《小白系列：如何將軟件裝成service》

該午休了，未完待續(xù)---2018-09-11

午休結(jié)束了，現(xiàn)在開始繼續(xù)---2018-09-18

the first one
  都說建立專用的用戶組來運(yùn)行php和nginx那么好 我們?nèi)ソ⒁粋€(gè)最常見到的www-data
groupadd www-data
useradd www-data -g www-data -s /sbin/nologin -M
  然后還是修改配置文件

the second one
  找到nginx的站點(diǎn)目錄 /usr/local/nginx/html/
  新建一個(gè)文件叫phpinfo.php內(nèi)容是 
  (此時(shí)如果要通過http://你的ip地址/phpinfo.php，他會(huì)默認(rèn)給你下載下來這個(gè)php文件)

the thrid one
  找到nginx的配置文件夾/usr/local/nginx/conf中的nginx.conf
  編輯一下將其中的

  第二行的#user  nobody;
  改成user  www-data;

  第九行的#pid        logs/nginx.pid;
  改成 pid        /var/run/nginx/nginx.pid;

  將中間的
#location ~ .php$ {
#   root           html;
#    fastcgi_pass   127.0.0.1:9000;
#    fastcgi_index  index.php;
#    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
#    include        fastcgi_params;
#}

  改成這種
location ~ .php$ {
root           html;
fastcgi_pass   127.0.0.1:9000;
fastcgi_index  index.php;
fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
include        fastcgi_params;
}



the fourth one
  找到nginx的配置文件夾/usr/local/php7/etc/php-fpm.d中的www.conf
  將其中的23行24行
user = nobody
group = nobody
  改為
user = www-data
group = www-data




the end
  重啟一下php
  然后重啟一下nginx
  怎么重啟我上面有寫。這里就不重復(fù)了
  你在訪問一下 就會(huì)發(fā)現(xiàn)http://你的ip地址/phpinfo.php 可以解析了
 具體的文件我放在下面，大家可以對(duì)比一下

www.conf

; Start a new pool named "www".
; the variable $pool can be used in any directive and will be replaced by the
; pool name ("www" here)
[www]

; Per pool prefix
; It only applies on the following directives:
; - "access.log"
; - "slowlog"
; - "listen" (unixsocket)
; - "chroot"
; - "chdir"
; - "php_values"
; - "php_admin_values"
; When not set, the global prefix (or /usr/local/php7) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user"s group
;       will be used.
user = www-data
group = www-data

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   "ip.add.re.ss:port"    - to listen on a TCP socket to a specific IPv4 address on
;                            a specific port;
;   "[ip:6:addr:ess]:port" - to listen on a TCP socket to a specific IPv6 address on

;   "port"                 - to listen on a TCP socket to all addresses
;                            (IPv6 and IPv4-mapped) on a specific port;
;   "/path/to/unix/socket" - to listen on a unix socket.
; Note: This value is mandatory.
listen = 127.0.0.1:9000

; Set listen(2) backlog.
; Default Value: 511 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 511

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user

; When set, listen.owner and listen.group are ignored
;listen.acl_users =
;listen.acl_groups =

; List of addresses (IPv4/IPv6) of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be

; Default Value: any
;listen.allowed_clients = 127.0.0.1

; Specify the nice(2) priority to apply to the pool processes (only if set)
; The value can vary from -19 (highest priority) to 20 (lower priority)
; Note: - It will only work if the FPM master process is launched as root
;       - The pool processes will inherit the master process priority
;         unless it specified otherwise
; Default Value: no set
; process.priority = -19

; Choose how the process manager will control the number of child processes.
; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;
;   dynamic - the number of child processes are set dynamically based on the
;             following directives. With this process management, there will be
;             always at least 1 children.
;             pm.max_children      - the maximum number of children that can

;                                    state (waiting to process). If the number
;                                    of "idle" processes is less than this
;                                    number then some children will be created.

; Note: This value is mandatory.
pm = dynamic

; The number of child processes to be created when pm is set to "static" and the
; maximum number of child processes when pm is set to "dynamic" or "ondemand".
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI. The below defaults are based on a server without much resources. Don"t
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to "static", "dynamic" or "ondemand"
; Note: This value is mandatory.
pm.max_children = 5

; The number of child processes created on startup.
; Note: Used only when pm is set to "dynamic"

; The desired minimum number of idle server processes.
; Note: Used only when pm is set to "dynamic"
; Note: Mandatory when pm is set to "dynamic"

; The number of seconds after which an idle process will be killed.
; Note: Used only when pm is set to "ondemand"
; Default Value: 10s
;pm.process_idle_timeout = 10s;

; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify "0". Equivalent to PHP_FCGI_MAX_REQUESTS.

; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. It shows the following informations:
;   pool                 - the name of the pool;
;   process manager      - static, dynamic or ondemand;
;   start time           - the date and time FPM has started;

; By default the status page output is formatted as text/plain. Passing either
; "html", "xml" or "json" in the query string will return the corresponding
; output syntax. Example:
;   http://www.foo.bar/status
;   http://www.foo.bar/status?json
;   http://www.foo.bar/status?html
;   http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing "full" in the
; query string will also return status for each pool process.
; Example:
;   http://www.foo.bar/status?full
;   http://www.foo.bar/status?json&full
;   http://www.foo.bar/status?html&full
;   http://www.foo.bar/status?xml&full
; The Full status returns for each process:
;   pid                  - the PID of the process;
;   state                - the state of the process (Idle, Running, ...);
;   start time           - the date and time the process has started;
;   start since          - the number of seconds since the process has started;
;   requests             - the number of requests the process has served;
;   request duration     - the duration in μs of the requests;
;   request method       - the request method (GET, POST, ...);
;   request URI          - the request URI with the query string;
;   content length       - the content length of the request (only with POST);
;   user                 - the user (PHP_AUTH_USER) (or "-" if not set);
;   script               - the main script called (or "-" if not set);
;   last request cpu     - the %cpu the last request consumed
;                          it"s always 0 if the process is not in Idle state
;                          because CPU calculation is done when the request
;                          processing has terminated;
;   last request memory  - the max amount of memory the last request consumed
;                          it"s always 0 if the process is not in Idle state
;                          because memory calculation is done when the request
;                          processing has terminated;
; If the process is in Idle state, then informations are related to the

; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_slowlog_timeout = 0

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the "max_execution_time" ini option
; does not stop script execution for some reason. A value of "0" means "off".

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: you can prefix with "$prefix" to chroot to the pool prefix or one
; of its subdirectories. If the pool prefix is not set, the global prefix
; will be used instead.
; Note: chrooting is a great security feature and should be used whenever
;       possible. However, all PHP paths will be relative to the chroot
;       (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =

; Chdir to this directory at the start.
; Note: relative path can be used.

; Default Value: no
;catch_workers_output = yes

; Clear environment in FPM workers
; Prevents arbitrary environment variables from reaching FPM worker processes
; by clearing the environment in workers before env vars specified in this

; Setting to "no" will make all environment variables available to PHP code
; via getenv(), $_ENV and $_SERVER.
; Default Value: yes
;clear_env = no

; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; execute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php

; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
;   php_value/php_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call "ini_set".
;   php_admin_value/php_admin_flag - these directives won"t be overwritten by
;                                     PHP call "ini_set"
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining "extension" will load the corresponding shared extension from
; extension_dir. Defining "disable_functions" or "disable_classes" will not
; overwrite previously defined php.ini values, but will append the new value
; instead.

; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr/local/php7)

; Default Value: nothing is defined by default except the values in php.ini and
;                specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
;php_flag[display_errors] = off
;php_admin_value[error_log] = /var/log/fpm-php.www.log
;php_admin_flag[log_errors] = on
