比眉伴天荒 2024-04-18 00:44 16阅读 0赞

Inception 是一个集审核、执行、备份及生成回滚语句于一身的MySQL自动化运维工具，支持MySQL 5.5、5.6以及Percona等主流版本。  
  
测试环境：CentOS 6.9  
下载源码  
\[root@MySQL01 ~\]\# cd /fire/  
\[root@MySQL01 fire\]\# mkdir inception  
\[root@MySQL01 fire\]\# cd inception/  
\[root@MySQL01 inception\]\# git clone https://github.com/mysql-inception/inception.git  
Initialized empty Git repository in /fire/inception/inception/.git/

安装依赖包  
yum install bison  
yum install cmake  
yum install ncurses-devel  
yum install openssl-devel  
yum install gcc-c++ libgcc gcc  
  
通过sh inception\_build.sh debug脚本方式安装  
\[root@MySQL01 inception\]\# sh inception\_build.sh debug

备份及回滚语句的生成条件：  
线上服务器必须要打开 binlog，在启动时需要设置参数log\_bin、log\_bin\_index等关于 binlog 的参数。不然不会备份及生成回滚语句。  
参数binlog\_format必须要设置为 mixed 或者 row 模式。  
参数 server\_id 必须要设置为非0及非1。
