生产库自动化MySQL5.6安装部署详细教程_MySQL

脚本中已经注释说明一些基本的安装信息

本脚本默认启用5.6部分新特性

innodb_buffer_pool_dump_at_shutdown=1 它dump的不是数据，是Id号
innodb_buffer_pool_load_at_startup=1

开启这个两个参数当数据库重启后把这些热数据重新加载回去

只有正常关库才会dump热数据块，宕机和kill -9不会

部分参数按需整改，例如innodb_buffer_pool_size = 512M，本文给的512M，一般给内存的50%-80%。

来看一下脚本的具体情况[root@HE3 ~]# cat mysql_auto_install.sh

######二进制自动安装数据库脚本root密码MANAGER将脚本和安装包放在/root目录即可###############
######数据库目录/usr/local/mysql############
######数据目录/data/mysql############
######日志目录/log/mysql############
######端口号默认3306其余参数按需自行修改############
