docker lnmp配置

1.lnmp网络与目录规划

172.16.10.0/24

nginx:172.16.10.10
mysql:172.16.10.20
php:172.16.10.30
网站访问主目录:/wwwroot
nginx的配置文件:/docker/nginx
mysql持久化的目录: /docker/mysql
mysql 密码: Aa123456

2.起临时nginx容器获取nginx配置文件

[root@docker ~]# mkdir /docker /wwwroot
[root@docker ~]# docker run -itd --name test nginx
[root@docker ~]# docker cp test:/etc/nginx /docker/
[root@docker ~]# docker cp test:/usr/share/nginx/html /wwwroot/
[root@docker ~]# docker rm -f test

3.创建自定义网络

#创建自定义网络
docker network create -d bridge --subnet 172.16.10.0/24 --gateway 172.16.10.1 lnmp

#服务器开启内核转发：
echo '1' >/proc/sys/net/ipv4/ip_forward

#重启容器服务
systemctl restart docker

4. 启动php容器

docker run -itd --name lnmp-php7.4 \
-p 9000:9000 \
-v /wwwroot/html:/usr/share/nginx/html \
--network lnmp \
--ip 172.16.10.30 \
registry.cn-hangzhou.aliyuncs.com/chenleilei/php74:latest

5. 启动nginx容器

docker run -d --name lnmp-nginx \
-p 80:80 \
-p 443:443 \
-v /wwwroot/html:/usr/share/nginx/html \
-v /docker/nginx:/etc/nginx \
--network lnmp \
--ip 172.16.10.10 nginx

#修改配置文件:
vim /docker/nginx/conf.d/default.conf

[root@node02 conf.d]# egrep -v '#|^$' /docker/nginx/conf.d/default.conf
server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;
    location / {
        root   /usr/share/nginx/html;           #修改html所在目录
        index  index.php index.html index.htm;  #添加默认首页文件 index.php
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
 #解除PHP注释，改为如下：
    location ~ \.php$ {
        root           /usr/share/nginx/html;  #添加PHP解析能力
        fastcgi_pass   172.16.10.30:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;  #修改为当前配置
        include        fastcgi_params;
    }
}

#server区段改为上面的配置后保存

6. 测试代码

docker restart lnmp-nginx lnmp-php7.4

cd /wwwroot/html
echo test > index.html
cat index.php

<?php
phpinfo();
?>

chmod -R a+w  /wwwroot/html

7. 其他配置[php容器增加mysql支持]

部署动态站点需要赋予目录足够权限，推荐
docker exec -it lnmp-nginx bash
#chown -R www-data.www-data /usr/share/nginx/html 可以不用
chmod -R a+w /usr/share/nginx/html
exit

chown -R root.root /wwwroot/html

此时已经可以运行php了，还有一些扩展需要部署如： GD支持 MySQL支持,可以在部署dede程序时看到
docker部署的php容器需要 安装扩展

#进入容器
docker exec -it lnmp-php7.4 bash
修改源：
sed -i 's#http://deb.debian.org#https://mirrors.163.com#g' /etc/apt/sources.list
apt-get update

安装软件支持:
apt-get install -y libfreetype6-dev libjpeg62-turbo-dev libmcrypt-dev libpng-dev libonig-dev
docker-php-ext-install gd mysqli pdo pdo_mysql mbstring shmop

安装完成后退出重启php容器
exit
docker restart lnmp-php7.4

没有安装扩展提示:

安装扩展后:

8. 启动mysql容器

#启动mysql
[root@docker html]# docker run -itd --name test -e MYSQL_ROOT_PASSWORD=Aa123456 registry.cn-hangzhou.aliyuncs.com/chenleilei/mysql5.7 

#测试创建库
[root@docker html]# docker exec -it test bash
root@d46a7cc8407f:/# mysql -uroot -pAa123456
mysql> show databases;
mysql> create database test;

mysql> show databases;

+--------------------+
5 rows in set (0.00 sec)

mysql> exit
root@d46a7cc8407f:/var/lib/mysql# exit

#获取mysql数据:
[root@docker html]# docker cp test:/var/lib/mysql  /docker
[root@docker html]# docker rm -f test

启动mysql:
docker run -d  --name lnmp_mysql \
--network lnmp --ip 172.16.10.20 \
-p 3306:3306 -p 33060:33060 \

登录mysql：
[root@docker html]# docker exec -it lnmp_mysql bash
root@60b705b2b10e:/# mysql -uroot -p'Aa123456'
mysql> exit

9. 测试部署php项目

9.1 部署dedecms

# 进入数据库容器：
docker exec -it lnmp_mysql bash

#创建运行wordpress的mysql数据库和用户：

mysql> create database dede;
Query OK, 1 row affected (0.00 sec)

mysql> grant all on dede.* to dede@'%' identified by 'dede';
Query OK, 0 rows affected, 1 warning (0.01 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

#下载DedeCMS
#wget https://cn.wordpress.org/latest-zh_CN.tar.gz

mkdir /wwwroot/html/dede
cd /wwwroot/html/dede

#添加权限
[root@node02 html]# chmod -R a+w /wwwroot/html

#nginx容器添加权限
docker exec -it lnmp-nginx bash
chown -R www-data.www-data /usr/share/nginx/html/dede
exit

后台登录不显示验证码经检查属于程序bug与配置无关，安装wordpress 无此故障

9.2 部署wordpress

创建数据库:
[root@node02 wordpress]# docker exec -it lnmp_mysql bash
root@059faa26e36a:/# mysql -uroot -p'Aa123456'

下载wordpress源码，解压到wordpress目录下
[root@node02 wordpress]# tar xf wordpress-4.7.3-zh_CN.tar.gz
[root@node02 wordpress]# mv wordpress/* .
[root@node02 wordpress]# chown -R root.root *

web安装页面:

目录授权:
[root@node02 html]# chmod -R 755 wordpress
[root@node02 html]# chmod -R a+w wordpress

#应该只执行这个就可以了
[root@node02 html]# docker exec -it lnmp-nginx bash
root@42ceb54db60c:/# chown -R www-data.www-data /usr/share/nginx/html/wordpress
