创建mysql用户与用户组

[root@MYSQLDB ~]# groupadd mysql

[root@MYSQLDB ~]# useradd -r -g mysql mysql

安装mysql

[root@MYSQLDB ~]# tar zxvf mysql-5.6.19.tar.gz

[root@MYSQLDB ~]# cd mysql-5.6.19

[root@MYSQLDB mysql-5.6.19]# cmake ./ -DCMAKE_INSTALL_PREFIX=/opt/mysql/ -DMYSQL_DATADIR=/opt/mysql/data -DMYSQL_UNIX_ADDR=/opt/mysql/data/mysqld.sock -DWITH_INNOBASE_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1
