rancher 2.X 搭建小型web集群+mysql主从复制

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

　　　　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.
