}

创建nginx运行脚本

 root@deploy:/dockerfile/project/nginx# cat run_nginx.sh 
#!/bin/bash
/usr/local/nginx/sbin/nginx
tail -f /usr/local/nginx/logs/access.log /usr/local/nginx/logs/error.log

创建nginx业务镜像Dockerfile

 root@deploy:/dockerfile/project/nginx# cat Dockerfile 
FROM harbor.cncf.net/web/nginx:1.20.2 
 
ADD nginx.conf /usr/local/nginx/conf/nginx.conf
ADD run_nginx.sh /usr/local/nginx/sbin/run_nginx.sh
RUN mkdir /usr/local/nginx/html/wordpress
RUN chown nginx.nginx /usr/local/nginx/html/wordpress/ -R
 
EXPOSE 80 443
 
CMD ["/usr/local/nginx/sbin/run_nginx.sh"]

创建构建脚本

 root@deploy:/dockerfile/project/nginx# cat build-command.sh 
#!/bin/bash
TAG=$1
docker build -t  harbor.cncf.net/project/wordpress-nginx:${TAG} .
 
docker push  harbor.cncf.net/project/wordpress-nginx:${TAG}

构建php镜像

创建Dockerfile

 root@deploy:/dockerfile/project/php# cat Dockerfile 
FROM harbor.cncf.net/os/centos:7.9
 
RUN useradd nginx
 
RUN yum install -y  https://mirrors.tuna.tsinghua.edu.cn/remi/enterprise/remi-release-7.rpm && yum install  php56-php-fpm php56-php-mysql -y 
ADD www.conf /opt/remi/php56/root/etc/php-fpm.d/www.conf
ADD run_php.sh /usr/local/bin/run_php.sh
EXPOSE 9000
 
CMD ["/usr/local/bin/run_php.sh"]

创建php-fpm容器运行脚本

 root@deploy:/dockerfile/project/php# cat run_php.sh 
#!/bin/bash
#echo "nameserver 10.20.254.254" > /etc/resolv.conf
 
/opt/remi/php56/root/usr/sbin/php-fpm
#/opt/remi/php56/root/usr/sbin/php-fpm --nodaemonize
tail -f /etc/hosts

创建php-fpm运行配置文件

 root@deploy:/dockerfile/project/php# grep -Ev "^;|^$" www.conf 
[www]
user = nginx
group = nginx
listen = 0.0.0.0:9000
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
slowlog = /opt/remi/php56/root/var/log/php-fpm/www-slow.log
php_admin_value[error_log] = /opt/remi/php56/root/var/log/php-fpm/www-error.log
php_admin_flag[log_errors] = on
php_value[session.save_handler] = files
php_value[session.save_path]    = /opt/remi/php56/root/var/lib/php/session
php_value[soap.wsdl_cache_dir]  = /opt/remi/php56/root/var/lib/php/wsdlcache

创建镜像构建脚本

 root@deploy:/dockerfile/project/php# cat build-command.sh
#!/bin/bash
TAG=$1
docker build -t harbor.cncf.net/project/wordpress-php-5.6:${TAG} .
docker push harbor.cncf.net/project/wordpress-php-5.6:${TAG}

创建wordpress资源

准备nfs共享目录

 root@harbor:/data/k8sdata# mkdir /data/k8sdata/wordpress
root@harbor:/data/k8sdata/wordpress# cat /etc/exports
/data/volumes2 *(rw,sync,no_root_squash)
root@harbor:/data/k8sdata/wordpress# exportfs -r

准备wordpress站点文件

下载wordpress

 root@harbor:/data/k8sdata/wordpress# wget https://cn.wordpress.org/wordpress-5.0.16-zh_CN.tar.gz
root@harbor:/data/k8sdata/wordpress# tar xf wordpress-5.0.16-zh_CN.tar.gz 
root@harbor:/data/k8sdata/wordpress# mv wordpress/* .
root@harbor:/data/k8sdata/wordpress# rm -fr wordpress
root@harbor:/data/k8sdata/wordpress# rm -f wordpress-5.0.16-zh_CN.tar.gz

获取nginx用户uid和gid并给与nfs站点目录相应权限

k8s节点查看用户属主属组对应uid和gid号

 root@deploy:/dockerfile/project/php# kubectl exec -it wordpress-app-deployment-78cfdc88f7-psvc4 -c wordpress-app-php -- id nginx
uid=1000(nginx) gid=1000(nginx) groups=1000(nginx)
root@deploy:/dockerfile/project/php# kubectl exec -it wordpress-app-deployment-78cfdc88f7-psvc4 -c wordpress-app-nginx -- id nginx
uid=1000(nginx) gid=1000(nginx) groups=1000(nginx)

nfs-server设置查看NFS共享目录赋予wordpress容器用户和组权限

 root@harbor:/data/k8sdata# chown 1000.1000 -R wordpress

创建namespace命名空间

 root@deploy:/dockerfile/project/wordpress# kubectl create ns wordpress
namespace/wordpress created

准备wordpress yaml资源文件

 root@deploy:/dockerfile/project# cat wordpress/wordpress.yaml 
kind: Deployment

数据库添加wordpress账户权限

 root@deploy:~# kubectl exec -it -n mysql-test mysql-0 -c mysql -- bash
root@mysql-0:/# mysql -u root -p123456 -P3360
mysql> grant all on wordpress.* to "wordpress"@"%" identified by 'wordpress123456';
mysql> create database wordpress;

客户端访问wordpress

由于mysql端口是非默认3306，所以需要修改wordpress数据库连接php代码文件

输入数据库名称 wordpress

输入用户名 wordpress

输入密码 wordpress123456

输入数据库主机为k8s 创建的mysql主库全名称:端口号mysql-0.mysql.mysql-test.svc.cluster.local:3360
