安装php7.2并且整合nginx且分开部署

1.安装php 7.2

2.php配置

3.nginx配置

4.测试

5.报错与解决

6.利用upstream实现负载均衡

1.安装php 7.2

启动容器:

 liwangdeMacBook-Air:~ liwang$ docker run -i -t --name php --net mynetwork --ip : centos /bin/bash

复制php至容器

 liwangdeMacBook-Air:~ liwang$ docker .tar.gz php:/soft

安装插件

 [root@6aaa15f97607 php-]# yum install gcc gcc-c++ make libxml2 libxml2-devel libpng libpng-devel -y

编译php

 [root@6aaa15f97607 html]# ./configure --prefix=/usr/local/php --with-pdo-mysql --enable-mysqlnd --with-gd --enable-gd-jis-conv --enable-fpm --with-mysqli=mysqlnd
 [root@6aaa15f97607 html]# make && make install

2.配置PHP

1.复制php-fpm.conf

 [root@6aaa15f97607 php-]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

2.复制www.conf

 [root@6aaa15f97607 php-]# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf

3.修改www.conf

查看php容器ip地址

 liwangdeMacBook-Air:~ liwang$ docker inspect -f {{.NetworkSettings.Networks.mynetwork.IPAddress}} php
 172.18.0.5
 liwangdeMacBook-Air:~ liwang$ 

修改www.con listen为容器ip,具体如下:

 [root@6aaa15f97607 php-fpm.d]# sed -n "34,38p" /usr/local/php/etc/php-fpm.d/www.conf
 ;   '/path/to/unix/socket' - to listen on a unix socket.
 ; Note: This value is mandatory.
 listen = 

 ; Set listen() backlog.
 [root@6aaa15f97607 php-fpm.d]# 

4.启动php-fpm

 [root@6aaa15f97607 php-fpm.d]#/usr/local/php/sbin/php-fpm
 [root@6aaa15f97607 php-fpm.d]#

5.查看启动状态

 [root@6aaa15f97607 php-fpm.d]#netstat -tulnp
 Active Internet connections (only servers)
 Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
 tcp                        /php-fpm: mast
 tcp                       0.0.0.0:*               LISTEN      -
 udp                       0.0.0.0:*                           -
 [root@6aaa15f97607 php-fpm.d]# ps aux
 USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
 root              pts/    Ss   :   : /bin/bash
 root          ?        Ss   :   : php-fpm: master process (/usr/local/php/etc/php-fpm.conf)
 nobody       ?        S    :   : php-fpm: pool www
 nobody       ?        S    :   : php-fpm: pool www
 root          pts/    R+   :   : ps aux
 [root@6aaa15f97607 php-fpm.d]# 

3.nginx配置

1.nginx.conf配置如下:

注意index中需要设置添加index.php,location php需要注意fastcgi_pass和fastcgi_param项

 [root@dbc19df20116 www]# sed -n "32,82p" /usr/local/nginx/conf/nginx.conf | egrep -v "#|^$"
     keepalive_timeout  ;
     server {
         listen       ;
         server_name  localhost;
         location / {
             root   html;
             index  index.php index.html index.htm;
         }
         error_page        /50x.html;
         location = /50x.html {
             root   html;
         }
         location ~ \.php$ {
             root           html;
             fastcgi_pass   ;
             fastcgi_index  index.php;
             fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
             include        fastcgi_params;
         }
     }
 [root@dbc19df20116 www]# 

2.由于fastcgi_pass连接至不同的服务器，故php服务器需要设置index root

 [root@6aaa15f97607 php-fpm.d]# ls -l /usr/local/nginx/html/index.php
 -rw-r--r--  root root  May  : /usr/local/nginx/html/index.php
 [root@6aaa15f97607 php-fpm.d]# 

4.测试

 [root@dbc19df20116 www]# curl localhost
 Hello,This is PHP server site
 [root@dbc19df20116 www]# 

5.报错与解决

 [root@dbc19df20116 www]# cat /usr/local/nginx/logs/error.log
 // :: [notice] #: signal process started
 // :: [alert] #: sched_setaffinity() failed (: Invalid argument)
 // :: [error] #: * FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 172.18.0.1, server: localhost, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://172.18.0.5:9000", host: "localhost"
 [root@dbc19df20116 www]# 

1.如果nginx与php服务器是分开部署的话,如错误日志所属,那么172.18.0.5这台服务器上需要有nginx的root文件,既index.php,添加后解决此问题。

2.如果nginx与php是在同一服务器,且php是使用127.0.0.1进行连接的话,那么可以修改nginx.conf为:

(fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;)

6.利用upstream实现负载均衡

环境:在服务器172.18.0.5上构建两台php,其端口分别为9000以及9001

 [root@6aaa15f97607 ~]# netstat -tulnp
 Active Internet connections (only servers)
 Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
 tcp                       0.0.0.0:*               LISTEN      -
 tcp                        /php-fpm: master
 tcp                        /php-fpm: master
 udp                       0.0.0.0:*                           -
 [root@6aaa15f97607 ~]# 

在nginx本地构建一台php,其端口为9000

 [root@dbc19df20116 conf]# netstat -tulnp
 Active Internet connections (only servers)
 Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
 tcp                       0.0.0.0:*               LISTEN      -
 tcp                         /php-fpm: master
 tcp                             /nginx: master pr
 udp                       0.0.0.0:*                           -
 [root@dbc19df20116 conf]# 

修改nginx配置文件nginx.conf

upstream作用域http标签内

其后状态值含义如下:

weight:值越大，负载则越重

backup:当其他机器忙或则down时，数据才会请求backup机器，因此，此机器负载最轻

down:表示该机器不参与负载

例如，如下配置，将负载压在172.18.0.5上，127.0.0.1则作为备份机

upstream siteidc{

server 172.18.0.5:9000 weight=2;

server 172.18.0.5:9001 weight=1;

server 127.0.0.1:9000 backup;

}

location设置如下，将fastcgi_pass压为upstream的值即可。

location ~ \.php$ {

root           html;

fastcgi_pass   siteidc;

fastcgi_index  index.php;

fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;

include        fastcgi_params;

}

整体nginx.conf文件如下:

 [root@dbc19df20116 conf]# cat nginx.conf | grep -v "^$" | grep -v "#"
 worker_processes  ;
 worker_cpu_affinity    ;
 worker_rlimit_nofile ;
 events {
     use epoll;
     worker_connections  ;
 }
 http {
     upstream siteidc{
         server  weight=;
         server  weight=;
         server  backup;
     }
     include       mime.types;
     default_type  application/octet-stream;
     sendfile        on;
     keepalive_timeout  ;
     server {
         listen               default backlog=;
         server_name  localhost;
         location / {
             root   html;
             index  index.php index.html index.htm;
         }
         error_page        /50x.html;
         location = /50x.html {
             root   html;
         }
         location ~ \.php$ {
             root           html;
             fastcgi_pass   siteidc;
             fastcgi_index  index.php;
             fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
             include        fastcgi_params;
         }
     }
     server {
     listen ;
     server_name www.wang-li.top;

     location / {
         root html/www;
         index index.html index.php;
     }
     location ~ \.php$ {
         root html/www;
         fastcgi_pass ;
         fastcgi_index index.php;
         fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html/www$fastcgi_script_name;
         include fastcgi_params;
     }
     }
 }
