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 172.18.0.5 -p 9000:9000 centos /bin/bash

复制php至容器

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

安装插件

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

2.复制www.conf

[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

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 = 172.18.0.5:9000

; Set listen(2) 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

[root@6aaa15f97607 php-fpm.d]# 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 "#|^$"   
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        location / {
            root   html;
            index  index.php index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
        location ~ \.php$ {
            root           html;
            fastcgi_pass   172.18.0.5:9000;
            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-- 1 root root 21 May 14 14:24 /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 
2018/05/14 14:08:09 [notice] 25607#0: signal process started
2018/05/14 14:08:09 [alert] 25611#0: sched_setaffinity() failed (22: Invalid argument)
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"
[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      0 127.0.0.11:43655        0.0.0.0:*               LISTEN      -                   
tcp        0      0 172.18.0.5:9000         0.0.0.0:*               LISTEN      46/php-fpm: master  
tcp        0      0 172.18.0.5:9001         0.0.0.0:*               LISTEN      17/php-fpm: master  
udp        0      0 127.0.0.11:50582        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      0 127.0.0.11:35111        0.0.0.0:*               LISTEN      -                   
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      42/php-fpm: master  
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      23/nginx: master pr 
udp        0      0 127.0.0.11:57311        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 "#"

    }
