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:
1[root@k8s3mysql]# cat docker-compose.yml 2version:'2' 3services: 4mysql-master: 5build: 6context: ./ 7dockerfile: master/Dockerfile 8environment: 9-"MYSQL_ROOT_PASSWORD=root"10-"MYSQL_DATABASE=replicas_db"11links:12- mysql-slave13ports:14-"33065:3306"15restart: always16hostname: mysql-master17mysql-slave:18build:19context: ./20dockerfile: slave/Dockerfile21environment:22-"MYSQL_ROOT_PASSWORD=root"23-"MYSQL_DATABASE=replicas_db"24ports:25-"33066:3306"26restart: always27hostname: mysql-slave

运行命令:
1 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 tag192.168.0.167/web/ngphp:v0.1192.168.0.167/web/ngphp:v3
docker tag 192.168.0.167/web/mysql-slave:0.1192.168.0.167/web/mysql-slave:v0.1docker tag 192.168.0.167/web/mysql-master:0.1192.168.0.167/web/mysql-master:v0.1
登入harbor私有仓库
dockerpush192.168.0.167/web/web1:v0.1docker push192.168.0.167/web/mysql-master:v0.1docker push192.168.0.167/web/mysql-slave:v0.1
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
1CHANGE 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:
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=154;
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
