docker compose部署wordpress

准备机器：

192.168.58.151  （关闭防火墙和selinux）

安装好docker服务        （详细参照：http://t.csdnimg.cn/usG0s 中的国内源安装docker）

部署wordpress:

 创建目录：

[root@docker ~]# mkdir wordpress
[root@docker ~]# ls
anaconda-ks.cfg        wordpress       ip_fixed.sh      

获取wordpress的安装包：  cn.wordpress.org

​​

服务器端下载：

[root@docker ~]# cd wordpress/
[root@docker wordpress]# wget https://cn.wordpress.org/latest-zh_CN.tar.gz

 修改nginx.conf文件，并将其放在wordpress目录下

[root@docker wordpress]# cat nginx.conf 
# For more information on configuration, see:

#   * Official Russian Documentation: http://nginx.org/ru/docs/

    include             /etc/nginx/mime.types;

}

 在wordpress目录下创建Dockerfile

[root@docker wordpress]# vim Dockerfile 
# 设置基础镜像
FROM daocloud.io/library/centos:7

# 安装环境
RUN yum install -y epel-release \
; yum install -y nginx \
; yum install -y http://rpms.remirepo.net/enterprise/remi-release-7.rpm \
; yum install -y php80-php-xsl php80-php php80-php-cli php80-php-devel php80-php-gd php80-php-pdo php80-php-mysql php80-php-fpm \
; yum clean all

# 将代码包拷贝到镜像中
# RUN wget https://cn.wordpress.org/latest-zh_CN.tar.gz
ADD latest-zh_CN.tar.gz /usr/share/nginx

# 将配置文件拷贝到镜像中
COPY nginx.conf /etc/nginx/

# 将启动脚本拷贝到镜像中
COPY docker-entrypoint.sh /

# 在启动容器时执行脚本
CMD ["sh","/docker-entrypoint.sh"]

创建docker-entrypoint.sh文件并编辑，其目的是执行启动服务并将其hang住。

[root@docker wordpress]# vim docker-entrypoint.sh 
chmod 777 /usr/share/nginx/wordpress -R
nginx
/opt/remi/php80/root/usr/sbin/php-fpm
echo "nginx 和 php 启动成功"
tail -f /var/log/nginx/*

创建docker-compose.yaml文件，并进行编辑

[root@docker wordpress]# vim docker-compose.yaml 
version: '3'
services:
  wordpress:
    build: .
    container_name: wordpess-web
    ports:
      - "80:80/tcp"
      - "443:443/tcp"
    links:
      - mysql:wordpess.db.com
    depends_on:
      - mysql

  mysql:
    image: mysql:5.7
    container_name: wordpess-db
    environment:
      - MYSQL_ROOT_PASSWORD=123456
      - MYSQL_DATABASE=wordpress
    volumes:
      - /opt/wordpress/:/var/lib/mysql

查看文件及镜像

[root@docker wordpress]# ls
docker-entrypoint.sh  Dockerfile  latest-zh_CN.tar.gz  nginx.conf  docker-compose.yaml

[root@docker wordpress]# docker pull daocloud.io/library/centos:7
[root@docker wordpress]# docker pull mysql:5.7

使用docker compose命令进行启动

另启一个端口查询端口

[root@docker ~]# ss -nplt | grep 80
