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:

1 liwangdeMacBook-Air:~ liwang$ docker run -i -t --name php --net mynetwork --ip 172.18.0.5 -p 9000:9000 centos /bin/bash

复制php至容器

1 liwangdeMacBook-Air:~ liwang$ docker cp soft/php-7.2.5.tar.gz php:/soft

安装插件

1 [root@6aaa15f97607 php-7.2.5]# yum install gcc gcc-c++ make libxml2 libxml2-devel libpng libpng-devel -y

编译php

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

 

2.配置PHP

1.复制php-fpm.conf

1 [root@6aaa15f97607 php-7.2.5]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

2.复制www.conf

1 [root@6aaa15f97607 php-7.2.5]# 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

1 liwangdeMacBook-Air:~ liwang$ docker inspect -f {{.NetworkSettings.Networks.mynetwork.IPAddress}} php
2 172.18.0.5
3 liwangdeMacBook-Air:~ liwang$ 

修改www.con listen为容器ip,具体如下:

1 [root@6aaa15f97607 php-fpm.d]# sed -n "34,38p" /usr/local/php/etc/php-fpm.d/www.conf
2 ;   '/path/to/unix/socket' - to listen on a unix socket.
3 ; Note: This value is mandatory.
4 listen = 172.18.0.5:9000
5 
6 ; Set listen(2) backlog.
7 [root@6aaa15f97607 php-fpm.d]# 

4.启动php-fpm

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

5.查看启动状态

 1 [root@6aaa15f97607 php-fpm.d]#netstat -tulnp
 2 Active Internet connections (only servers)
 3 Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

 5 tcp        0      0 127.0.0.11:37421        0.0.0.0:*               LISTEN      -

 7 [root@6aaa15f97607 php-fpm.d]# ps aux

11 nobody   13408  0.0  0.5  50116 10328 ?        S    14:14   0:00 php-fpm: pool www
12 nobody   13409  0.0  0.5  50116 10328 ?        S    14:14   0:00 php-fpm: pool www

14 [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

 1 [root@dbc19df20116 www]# sed -n "32,82p" /usr/local/nginx/conf/nginx.conf | egrep -v "#|^$"   
 2     keepalive_timeout  65;
 3     server {
 4         listen       80;
 5         server_name  localhost;
 6         location / {
 7             root   html;
 8             index  index.php index.html index.htm;
 9         }
10         error_page   500 502 503 504  /50x.html;
11         location = /50x.html {
12             root   html;
13         }
14         location ~ \.php$ {
15             root           html;
16             fastcgi_pass   172.18.0.5:9000;
17             fastcgi_index  index.php;
18             fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
19             include        fastcgi_params;
20         }
21     }
22 [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

1 [root@6aaa15f97607 php-fpm.d]# ls -l /usr/local/nginx/html/index.php 
2 -rw-r--r-- 1 root root 21 May 14 14:24 /usr/local/nginx/html/index.php
3 [root@6aaa15f97607 php-fpm.d]# 

4.测试

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

5.报错与解决

1 [root@dbc19df20116 www]# cat /usr/local/nginx/logs/error.log 
2 2018/05/14 14:08:09 [notice] 25607#0: signal process started
3 2018/05/14 14:08:09  25611#0: sched_setaffinity() failed (22: Invalid argument)
4 2018/05/14 14:15:37 [error] 25611#0: *32 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"
5 [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

1 [root@6aaa15f97607 ~]# netstat -tulnp
2 Active Internet connections (only servers)
3 Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
4 tcp        0      0 127.0.0.11:43655        0.0.0.0:*               LISTEN      -                   
5 tcp        0      0 172.18.0.5:9000         0.0.0.0:*               LISTEN      46/php-fpm: master  
6 tcp        0      0 172.18.0.5:9001         0.0.0.0:*               LISTEN      17/php-fpm: master  
7 udp        0      0 127.0.0.11:50582        0.0.0.0:*                           -                   
8 [root@6aaa15f97607 ~]# 

在nginx本地构建一台php,其端口为9000

1 [root@dbc19df20116 conf]# netstat -tulnp
2 Active Internet connections (only servers)
3 Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
4 tcp        0      0 127.0.0.11:35111        0.0.0.0:*               LISTEN      -                   
5 tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      42/php-fpm: master  
6 tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      23/nginx: master pr 
7 udp        0      0 127.0.0.11:57311        0.0.0.0:*                           -                   
8 [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:

 1 [root@dbc19df20116 conf]# cat nginx.conf | grep -v "^$" | grep -v "#"
 2 worker_processes  4;
 3 worker_cpu_affinity 00000001 00000010 00000011 00000100;
