-rw-r--r-- 1 root root 27323722 Jul 19 19:12 wordpress-6.6-zh_TW.zip

二. 准备对应的配置文件

nginx官方镜像源文件

bash 复制代码
[root@localhost ~]# vim /root/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

nginx的配置文件

bash 复制代码
[root@localhost ~]# vim /root/default.conf 
server {
    listen       80;
    server_name  localhost;


    location / {
        root   /usr/share/nginx/wordpress;
        index  index.php;
    }

        location ~ \.php$ {
            root          /usr/share/nginx/wordpress;
            fastcgi_pass   unix:///var/opt/remi/php80/run/php-fpm/www.sock;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/wordpress;
    }
}

三. 编写Dockerfile

bash 复制代码
[root@localhost ~]# vim /root/Dockerfile
FROM rockylinux:9.3

LABEL \
  version="1.0" \
  description="wordpress" \
  maintainer="zzdict@gmail.com"

WORKDIR /root/
EXPOSE 80 443

# 安装 Remi 仓库和 PHP
RUN yum install -y http://rpms.remirepo.net/enterprise/remi-release-9.rpm && \
    yum install -y epel-release && \
    yum install php80-php-xsl php80-php php80-php-cli php80-php-devel php80-php-gd php80-php-pdo php80-php-mysql php80-php-fpm -y
# 复制 nginx repo 配置文件并安装 nginx
COPY nginx.repo /etc/yum.repos.d/nginx.repo
RUN yum install -y nginx

# 复制 nginx 配置文件
COPY default.conf /etc/nginx/conf.d/default.conf

# 复制 WordPress 并设置适当的权限
ADD wordpress-6.6-zh_CN.tar.gz /usr/share/nginx
RUN chown -R nginx:nginx /usr/share/nginx/wordpress

# 复制启动脚本
COPY start.sh /start.sh
RUN chmod +x /start.sh

# 设置启动命令
CMD ["/start.sh"]

创建启动服务的脚本

bash 复制代码
#!/bin/bash

# 启动 PHP-FPM
/opt/remi/php80/root/usr/sbin/php-fpm
chmod 777 /var/opt/remi/php80/run/php-fpm/www.sock

# 启动 Nginx
nginx -g 'daemon off;'

四. 构建镜像

bash 复制代码
[root@localhost ~]# docker build -t wordpress:v1 .


[root@localhost ~]# docker images 
REPOSITORY   TAG       IMAGE ID       CREATED         SIZE
wordpress    v1        6f9a0e03d62a   3 minutes ago   891MB


#创建并启动容器
[root@localhost ~]# docker run -dit -P 6f9a0e03d62a
f0cd32e390ab49a671d44aee2c36c695a98ec3d3a62a7f15f48c35a4f26e90af

[root@localhost ~]# docker ps
CONTAINER ID   IMAGE          COMMAND       CREATED          STATUS          PORTS                                                                                NAMES
f0cd32e390ab   6f9a0e03d62a   "/start.sh"   42 seconds ago   Up 42 seconds   0.0.0.0:32780->80/tcp, :::32780->80/tcp, 0.0.0.0:32781->443/tcp, :::32781->443/tcp   unruffled_poincare

浏览器访问IP+映射的端口

五. 配置MySQL

bash 复制代码
[root@localhost ~]# docker pull mysql:8.0

[root@localhost ~]# docker images
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
wordpress    v1        6f9a0e03d62a   7 hours ago   891MB
mysql        8.0       6c54cbcf775a   2 weeks ago   572MB

[root@localhost ~]# docker run --name mysql_wordpress -e MYSQL_ROOT_PASSWORD=Qaz123456+ -e MYSQL_DATABASE=wordpress -d mysql:8.0


[root@localhost ~]# docker ps
CONTAINER ID   IMAGE          COMMAND                  CREATED         STATUS         PORTS                                                                                NAMES
5d8b0b70665e   mysql:8.0      "docker-entrypoint.s..."   2 minutes ago   Up 2 minutes   3306/tcp, 33060/tcp                                                                  mysql_wordpress
f0cd32e390ab   6f9a0e03d62a   "/start.sh"              7 hours ago     Up 7 hours     0.0.0.0:32780->80/tcp, :::32780->80/tcp, 0.0.0.0:32781->443/tcp, :::32781->443/tcp   unruffled_poincare

#进入mysql容器验证是否创建成功
[root@localhost ~]# docker exec -it 5d8b0b70665e mysql -u root -p
Enter password:

按住ctrl + p + q 后台运行当前容器

#查看详细信息,找到IP
[root@localhost ~]# docker inspect 5d8b0b70665e

六. 安装wordpress

注:如果出现下图中的提示,需要进入nginx的哪个容器里去编写对应的配置

对应步骤如下:

bash 复制代码
[root@localhost ~]# docker ps
CONTAINER ID   IMAGE          COMMAND                  CREATED          STATUS          PORTS                                                                                NAMES
5d8b0b70665e   mysql:8.0      "docker-entrypoint.s..."   11 minutes ago   Up 11 minutes   3306/tcp, 33060/tcp                                                                  mysql_wordpress
f0cd32e390ab   6f9a0e03d62a   "/start.sh"              7 hours ago      Up 7 hours      0.0.0.0:32780->80/tcp, :::32780->80/tcp, 0.0.0.0:32781->443/tcp, :::32781->443/tcp   unruffled_poincare
[root@localhost ~]# docker exec -it f0cd32e390ab /bin/bash
[root@f0cd32e390ab /]# 

[root@f0cd32e390ab wordpress]# vi /usr/share/nginx/wordpress/wp-config.php
#将页面提示的配置代码全部粘贴并复制到该文件里

然后按ctrl + p +q 后台运行该容即可。

当配置完成后,点击执行安装程序即可。

七. 扩展

使用--link参数。

当数据库宕机了,我们重启一个数据库,那么容器的IP就会变,因此可以使用--link参数具体操作如下:

bash 复制代码
#查看镜像ID
[root@localhost ~]# docker images 
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
wordpress    v1        6f9a0e03d62a   7 hours ago   891MB
mysql        8.0       6c54cbcf775a   2 weeks ago   572MB

#查看mysql容器名
[root@localhost ~]# docker ps
CONTAINER ID   IMAGE          COMMAND                  CREATED          STATUS          PORTS                                                                                NAMES
5d8b0b70665e   mysql:8.0      "docker-entrypoint.s..."   32 minutes ago   Up 32 minutes   3306/tcp, 33060/tcp                                                                  mysql_wordpress
f0cd32e390ab   6f9a0e03d62a   "/start.sh"              7 hours ago      Up 7 hours      0.0.0.0:32780->80/tcp, :::32780->80/tcp, 0.0.0.0:32781->443/tcp, :::32781->443/tcp   unruffled_poincare

#重新创建一个容器,并和mysql容器名进行关联
[root@localhost ~]# docker run -dit -P --link=mysql_wordpress 6f9a0e03d62a
3ea2e9862b9a8b91c8b84e552665968a5ca6c10326ab367bd2bf602639638928


[root@localhost ~]# docker ps
CONTAINER ID   IMAGE          COMMAND                  CREATED              STATUS              PORTS                                                                                NAMES
3ea2e9862b9a   6f9a0e03d62a   "/start.sh"              About a minute ago   Up About a minute   0.0.0.0:32782->80/tcp, :::32782->80/tcp, 0.0.0.0:32783->443/tcp, :::32783->443/tcp   bold_mclaren
5d8b0b70665e   mysql:8.0      "docker-entrypoint.s..."   34 minutes ago       Up 34 minutes       3306/tcp, 33060/tcp                                                                  mysql_wordpress
f0cd32e390ab   6f9a0e03d62a   "/start.sh"              7 hours ago          Up 7 hours          0.0.0.0:32780->80/tcp, :::32780->80/tcp, 0.0.0.0:32781->443/tcp, :::32781->443/tcp   unruffled_poincare

查看到了刚创建的容器端口,现在浏览器进行访问IP+映射出来的端口、

这数据库宕了,可以重新起一个数据库容器,但是要求重新起的数据库容器名要和这里填写的mysql_wordpress一致。

bash 复制代码
[root@localhost ~]# docker ps
CONTAINER ID   IMAGE          COMMAND                  CREATED          STATUS          PORTS                                                                                NAMES
3ea2e9862b9a   6f9a0e03d62a   "/start.sh"              9 minutes ago    Up 9 minutes    0.0.0.0:32782->80/tcp, :::32782->80/tcp, 0.0.0.0:32783->443/tcp, :::32783->443/tcp   bold_mclaren
5d8b0b70665e   mysql:8.0      "docker-entrypoint.s..."   42 minutes ago   Up 42 minutes   3306/tcp, 33060/tcp                                                                  mysql_wordpress
f0cd32e390ab   6f9a0e03d62a   "/start.sh"              8 hours ago      Up 8 hours      0.0.0.0:32780->80/tcp, :::32780->80/tcp, 0.0.0.0:32781->443/tcp, :::32781->443/tcp   unruffled_poincare
[root@localhost ~]# docker exec -it 3ea2e9862b9a /bin/bash
[root@3ea2e9862b9a /]# vi /usr/share/nginx/wordpress/wp-config.php
#将页面提示的配置代码全部粘贴并复制到该文件里

然后按ctrl + p +q 后台运行该容即可。
