Rancher部署mysql8

环境变量设置

      设置root用户的密码

       

端口映射 

        

处理用户远程连接登录异常 

     create user 'taishi'@'%' identified by 'aransfar@123';
     grant all privileges on *.* to 'taishi'@'%' with grant option;
     flush privileges;

    ALTER USER 'taishi'@'%' IDENTIFIED WITH mysql_native_password BY 'aransfar@123';

    set global log_bin_trust_function_creators=1;

        

 处理mysql8在sql查询语句中不区分大小写字符

       

          

          

          docker run --name mysql -p 33306:3306  -v /home/admin/mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD="Transfar@123" ab2f358b8612  --lower-case-table-names=1

          --lower-case-table-names=1 相当于作为entrypoint.sh的命令参数 参数的前面需要加--

         

 所有服务正常连接数据库并启动

      数据库传输同步

         

          

版本兼容问题1

       mysql 8.0之后出的异常,MySQL 5.7.5及以上功能依赖检测功能,而使用的mysql是8.0版本.如果启用了ONLY_FULL_GROUP_BY SQL 模式（默认情况下）MySQL将拒绝选择列表,HAVING 条件或ORDER BY列表的查询引用在GROUP BY子句中既未命名的非集合列

        

       解决方法2

          打开mysql配置文件：my.cnf
          直接选择打开mysql配置文件，然后在最底部添加
          sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
          重启mysql

创建只有查询权限的用户

       mysql -uroot -pTransfar@123
       create user 'chaxun'@'%' identified by 'Tranar@123';
       grant select on *.* to 'chaxun'@'%' with grant option;
       flush privileges;
       ALTER USER 'chaxun'@'%' IDENTIFIED WITH mysql_native_password BY 'Trsfar@123';

Rancher搭建mysql主从集群

           

        mysql数据存储

         容器中的/var/lib/mysql 必须设置成有状态存储  这样即使容器重启 也不会使原来数据丢失

           

           mysql容器启动的时候提示

               ENTRYPOINT ["/bin/sh","/start-mysql.sh"]

               /bin/sh  start-mysql.sh  出现  let: not found

          修改Dockerfile

              ENTRYPOINT ["/bin/bash","/start-mysql.sh"]

         主从集群搭建步骤

          1.创建相关文件

           

        2.文件内容

mysql容器中添加自定义配置文件

      直接添加是不会生效的 需要修改配置的文件的属主和权限

       chown mysql:mysql /etc/mysql/conf.d/master.cnf
       chown mysql:mysql /etc/mysql/conf.d/slave.cnf

       chmod 644 /etc/mysql/conf.d/master.cnf
       chmod 644 /etc/mysql/conf.d/slave.cnf

      

     

    不修改文件权限mysql会直接忽略对应的配置文件,所以master.cnf中对应的配置就不会生效

    

source初始数据缓慢

        用navicat导出来的数据结构后然后在myql中使用source的话会非常的缓慢

        速度慢原因：200多万条数据，就 insert into 了200多万次

          

          

           用mysqldump工具导出,唯一区别是insert into方式不一样.一次insert可以同时插入多条记录

           mysqldump -uroot -p Transfar siem -e --max_allowed_packet=1048576 --net_buffer_length=16384 >siem2.sql
