Docker部署lnmp

前言 : 本篇文章仅仅使用docker基础 并未使用dockerfile等

部署lnmp之间通信的网络

[root@server nginx]# docker network create --subnet 192.168.0.0/16 --gateway 192.168.0.1 lnmp
[root@server nginx]# docker network ls
NETWORK ID     NAME      DRIVER    SCOPE
96127bef1da0   bridge    bridge    local
1ed463648b6e   host      host      local
e4b3d4a45cf5   lnmp      bridge    local
90e0f2c3f851   none      null      local

部署Nginx

# nginx
[root@server lnmp]# docker run \
-d \
-p 10002:80 \
--name Nginx \
-v /docker/lnmp/nginx/www/:/var/www/html \ 
-v /docker/lnmp/nginx/conf:/etc/nginx/conf.d \ 
--network lnmp nginx

-d											后台运行
-p											暴露端口
--name										设置容器名
-v											挂载目录
--network									设置网络连接方式

vim /docker/lnmp/nginx/conf/default.conf
server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;

    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        root           html;
        fastcgi_pass   PHP:9000;
        fastcgi_index  index.php;
       	fastcgi_param  SCRIPT_FILENAME  /var/www/html$fastcgi_script_name;
   	    include        fastcgi_params;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}
[root@server www]# docker exec -it Nginx bash service nginx reload
Reloading nginx: nginx.

部署mysql

# mysql
[root@server mysql]# docker run 
-e MYSQL_ROOT_PASSWORD=root \
-d \
--name Mysql \
--network lnmp \
-v /docker/lnmp/mysql/data/:/var/lib/mysql \
-v /docker/lnmp/mysql/conf:/etc/mysql/conf.d \
-p 10000:3306  mysql:5.7 

-e											设置环境变量
-d											后台运行
--name										设置容器名
--network									设置网络连接方式
-v											挂载目录
-p											暴露端口

部署PHP

[root@server lnmp]# docker run \
--name PHP \
-d \
-v /docker/lnmp/nginx/www:/var/www/html \
--network lnmp php:8.0.2-fpm 

--name										设置容器名
-d											后台运行
-v											挂载目录
--network									设置网络连接方式
