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 
# For more information on configuration, see:

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

#            location = /50x.html {
#        }
#    }}

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

开始build 并 run

[root@docker wordpress]# docker build -t  wordpress:1.0 .
[+] Building 0.1s (10/10) FINISHED                                                                            => [internal] load build definition from Dockerfile                                                     0.0s

nginx 和 php 启动成功
==> /var/log/nginx/access.log <====> /var/log/nginx/error.log <==

浏览器访问：192.168.58.151

服务器端另开端口启动MySQL镜像，并设置密码与数据库名

[root@docker wordpress]# docker run -itd -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=wordpress mysql:5.7
c7ec40a5eb7fa8e9f03707f629a58fc1769a0b6d9b69d97be06e440d46023464

查看服务并获取数据库的ip地址（172.17.0.3）

[root@docker wordpress]# docker ps -a

[root@docker wordpress]#

浏览器端进行填写

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
jenkins.war    jdk-17_linux-x64_bin.tar.gz    plugins-2.414.3.tar.gz
[root@docker jenkins]#

新建Dockerfile并编辑

[root@docker jenkins]# vim Dockerfile FROM daocloud.io/library/centos:7ADD jdk-17_linux-x64_bin.tar.gz /usr/localADD jenkins-2.414.3.war /usr/localENV JENKINS_HOME=/usr/local/.jenkinsENV JAVA_HOME /usr/local/jdk-17.0.7ENV PATH=$JAVA_HOME/bin:$PATHADD  plugins-2.414.3.tar.gz /usr/local/.jenkins/    #plugins包代替可以减少后期的安装时间RUN yum -y install fontconfigENTRYPOINT ["java","-jar","/usr/local/jenkins-2.414.3.war"]

构建镜像并创建容器

[root@docker jenkins]# docker build -t jenkins:1.0 .
[+] Building 0.1s (10/10) FINISHED                                                                            => [internal] load .dockerignore                                                                        ······=> => naming to docker.io/library/jenkins:1.0 [root@docker jenkins]# docker run -it -p 8080:8080 jenkins:1.0

另起端口看看8080端口是否启动

[root@docker ~]# ss -nplt | grep 8080
LISTEN     0      128          *:8080                     *:*                   users:(("docker-proxy",pid=25919,fd=4))

成功启动，浏览器访问 ip:8080 (192.168.58.151:8080)
