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@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] server_id=100 binlog-ignore-db=mysql log-bin=replicas-mysql-bin binlog_cache_size=1M binlog_format=mixed expire_logs_days=7 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 2 [mysqld] 3 server_id=101 4 binlog-ignore-db=mysql 5 log-bin=replicas-mysql-slave1-bin 6 binlog_cache_size=1M 7 binlog_format=mixed 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
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
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
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:
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
