rocky_linux9.4

Docker version 27.0.3

关闭防火墙和selinux，进行时间同步。

安装docker

# step 1: 安装必要的一些系统工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 添加软件源信息
sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# Step 3
sudo sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
# Step 4: 更新并安装Docker-CE
sudo yum makecache
sudo yum -y install docker-ce
# Step 4: 开启Docker服务
sudo service docker start
# 验证docker
sudo docker version

下载wordpress上传至/root/目录

发行版本归档 – WordPress.org China 简体中文https://cn.wordpress.org/download/releases/

[root@localhost ~]# ll

二. 准备对应的配置文件

nginx官方镜像源文件

[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

[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

[root@localhost ~]# vim /root/Dockerfile
FROM rockylinux:9.3LABEL \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

#!/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

[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

[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

[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：

[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：

#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。

[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。
