Docker部署wordpress和Jenkins
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

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/*查看文件及镜像
[root@docker wordpress]# ls
docker-entrypoint.sh Dockerfile latest-zh_CN.tar.gz nginx.conf[root@docker wordpress]# docker pull daocloud.io/library/centos:7
[root@docker wordpress]# docker pull mysql:5.7

后续按需填写即可。
部署jenkins:
获取jenkins.war包请到官网下载：Jenkins download and deployment
创建目录并上传jdk
[root@docker ~]# mkdir jenkins
[root@docker ~]# cd jenkins/
[root@docker jenkins]# ls
