一,环境配置

　　 rancher 2.1.6

二,配置harbor私有仓库

　　见上文

三,配置私有镜像

　　　01,总文件

　　　dockerfile 为主配置文件,html 为站点文件wordpress.,官网下载更加

 FROM centos:7.4.

　　　　02,构建镜像

docker build -t web-:v3 .

　　　 03,搭建mysql镜像

　　　　可以通过官方的docker镜像源进行安装比较块

wget https://codeload.github.com/docker-library/mysql/zip/master

　　　另一种自定义:

 [root@k8s3 mysql]# cat docker-compose.yml

 version: '2'

 services:

   mysql-master:

     build:

       context: ./

       dockerfile: master/Dockerfile

     environment:

       - "MYSQL_ROOT_PASSWORD=root"

       - "MYSQL_DATABASE=replicas_db"

     links:

       - mysql-slave

     ports:

       - "33065:3306"

     restart: always

     hostname: mysql-master

   mysql-slave:

     build:

       context: ./

       dockerfile: slave/Dockerfile

     environment:

       - "MYSQL_ROOT_PASSWORD=root"

       - "MYSQL_DATABASE=replicas_db"

     ports:

       - "33066:3306"

     restart: always

     hostname: mysql-slave

 [root@k8s3 mysql]# cat master/Dockerfile

 FROM mysql:5.7.

 MAINTAINER kingle

 ADD ./master/my.cnf /etc/mysql/my.cnf

 EXPOSE

 CMD ["mysqld"]

[root@k8s3 mysql]# cat master/my.cnf

[mysqld]

server_id=

binlog-ignore-db=mysql

log-bin=replicas-mysql-bin

binlog_cache_size=1M

 binlog_format=mixed

expire_logs_days=

slave_skip_errors=

 [root@k8s3 mysql]# cat slave/Dockerfile

 FROM mysql:5.7.

 MAINTAINER kingle

 ADD ./slave/my.cnf /etc/mysql/my.cnf

 EXPOSE

 CMD ["mysqld"]

 [root@k8s3 mysql]# cat slave/my.cnf

 [mysqld]

 server_id=

 binlog-ignore-db=mysql

 log-bin=replicas-mysql-slave1-bin

 binlog_cache_size=1M

  binlog_format=mixed

 expire_logs_days=

 slave_skip_errors=

 relay_log=replicas-mysql-relay-bin

 log_slave_updates=

 read_only=

运行命令:

　　 docker-compose up -d

等待配置完成

四,push镜像到harbor

　　docker images 可以看见编排出来的包,

　　这三个包弄了一下午的编排

docker tag 192.168.0.167/web/ngphp:v0. 192.168.0.167/web/ngphp:v3

docker tag 192.168.0.167/web/mysql-slave:0.1 192.168.0.167/web/mysql-slave:v0.

docker tag 192.168.0.167/web/mysql-master:0.1 192.168.0.167/web/mysql-master:v0.

　　登入harbor私有仓库

docker push 192.168.0.167/web/web1:v0.

docker push 192.168.0.167/web/mysql-master:v0.

docker push 192.168.0.167/web/mysql-slave:v0.

　　到harbor查看

　　上传成功了

五,rancher 搭建

　　配置rancher

等待启动完成

站点访问:

六,配置数据库主从

　　主库从库搭建就命名不一样,其余参照下面搭建

　　　点击启动即可

　　　　　　查看你

　　查看主库ip

命令编辑

　　授权给从库

　　create user 'repl'@'%' identified by '123456'
　　GRANT REPLICATION SLAVE ON *.* to 'rep1'@'%' identified by '123456';
　　FLUSH PRIVILEGES;
　  show mater slave

从库配置

 CHANGE MASTER TO MASTER_HOST='10.42.1.31', MASTER_USER='repl', MASTER_PASSWORD='123456', MASTER_LOG_FILE='replicas-mysql-bin.000003',MASTER_LOG_POS=;

　　发现一个问题:

　　解决:

　　主库:

　　刷写日志: 记录好binlog 和pos

　　从库

　　stop slave

stop slave ;

reset slave;

CHANGE MASTER TO MASTER_HOST='10.42.1.31', MASTER_USER='repl', MASTER_PASSWORD='123456', MASTER_LOG_FILE='replicas-mysql-bin.000004',MASTER_LOG_POS=;

start slave;

　　　　成功解决

　　　　从库也一样了

七,wordpress 配置

　　根据步骤填写,回不去,少了截图,大家正常发挥,有问题联系,邮箱在下面.

　　　　点击安装即可
