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-11: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:

     rancher 2.X 搭建小型web集群+mysql主从复制_第1张图片

 1 [root@k8s3 mysql]# cat docker-compose.yml
 2 version: '2'
 3 services:
 4   mysql-master:
 5     build:
 6       context: ./
 7       dockerfile: master/Dockerfile
 8     environment:
 9       - "MYSQL_ROOT_PASSWORD=root"
10       - "MYSQL_DATABASE=replicas_db"
11     links:
12       - mysql-slave
13     ports:
14       - "33065:3306"
15     restart: always
16     hostname: mysql-master
17   mysql-slave:
18     build:
19       context: ./
20       dockerfile: slave/Dockerfile
21     environment:
22       - "MYSQL_ROOT_PASSWORD=root"
23       - "MYSQL_DATABASE=replicas_db"
24     ports:
25       - "33066:3306"
26     restart: always
27     hostname: mysql-slave
1 [root@k8s3 mysql]# cat master/Dockerfile
2 FROM mysql:5.7.17
3 MAINTAINER kingle
4 ADD ./master/my.cnf /etc/mysql/my.cnf
5 EXPOSE 3306
6 CMD ["mysqld"]
[root@k8s3 mysql]# cat master/my.cnf
[mysqld]

slave_skip_errors=1062
1 [root@k8s3 mysql]# cat slave/Dockerfile
2 FROM mysql:5.7.17
3 MAINTAINER kingle
4 ADD ./slave/my.cnf /etc/mysql/my.cnf
5 EXPOSE 3306
6 CMD ["mysqld"]
 1 [root@k8s3 mysql]# cat slave/my.cnf

 8 expire_logs_days=7
 9 slave_skip_errors=1062
10 relay_log=replicas-mysql-relay-bin
11 log_slave_updates=1
12 read_only=1

运行命令:

   1 docker-compose up -d 

等待配置完成

四,push镜像到harbor

     rancher 2.X 搭建小型web集群+mysql主从复制_第2张图片

  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:v0.1 192.168.0.167/web/ngphp:v3
docker tag 192.168.0.167/web/mysql-slave:0.1 192.168.0.167/web/mysql-slave:v0.1
docker tag 192.168.0.167/web/mysql-master:0.1 192.168.0.167/web/mysql-master:v0.1

  登入harbor私有仓库

 

docker push 192.168.0.167/web/web1:v0.1
docker push 192.168.0.167/web/mysql-master:v0.1
docker push 192.168.0.167/web/mysql-slave:v0.1

  到harbor查看

  上传成功了

五,rancher 搭建

    配置rancher

rancher 2.X 搭建小型web集群+mysql主从复制_第4张图片

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rancher 2.X 搭建小型web集群+mysql主从复制_第10张图片

  rancher 2.X 搭建小型web集群+mysql主从复制_第11张图片

rancher 2.X 搭建小型web集群+mysql主从复制_第12张图片

 

   点击启动即可

      查看你rancher 2.X 搭建小型web集群+mysql主从复制_第13张图片

  查看主库ip

rancher 2.X 搭建小型web集群+mysql主从复制_第14张图片

 

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

rancher 2.X 搭建小型web集群+mysql主从复制_第15张图片

rancher 2.X 搭建小型web集群+mysql主从复制_第16张图片

 

 

 从库配置

  rancher 2.X 搭建小型web集群+mysql主从复制_第17张图片

1 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=1144353;

   发现一个问题:rancher 2.X 搭建小型web集群+mysql主从复制_第18张图片

  解决:

  主库:

  刷写日志: 记录好binlog 和pos

  rancher 2.X 搭建小型web集群+mysql主从复制_第19张图片

  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=154;
start slave;

    rancher 2.X 搭建小型web集群+mysql主从复制_第20张图片

    成功解决

    rancher 2.X 搭建小型web集群+mysql主从复制_第21张图片

    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.rancher 2.X 搭建小型web集群+mysql主从复制_第22张图片
