二進制安裝：

[root@lufengcentos?~]#?mkdir?/home/lufeng/tools?-p

[root@lufengcentos?~]#?cd?/home/lufeng/tools

[root@lufengcentos?tools]#?rz

[root@lufengcentos?tools]#?tar?xf?mysql-5.5.49-linux2.6-x86_64.tar.gz

[root@lufengcentos?tools]#?mkdir?-p?/application/mysql-5.5.49

[root@lufengcentos?tools]#?mv?mysql-5.5.49-linux2.6-x86_64?/application/mysql-5.5.49

創建mysql用戶|組

[root@lufengcentos?tools]#?groupadd?mysql

[root@lufengcentos?tools]#?useradd?mysql?-g?mysql?-s?/sbin/nologin?-M

[root@lufengcentos?tools]#?ln?-s?/application/mysql-5.5.49/?/application/mysql

root@lufengcentos?mysql]#?sed?-i?'s#/usr/local/mysql#/application/mysql#g'?/application/mysql/bin/mysqld_safe

創建多實例數據文件目錄

[root@Mysql-server_2?~]#?mkdir?-p?/data/{3306,3307}/data

配置相應的配置文件：

[root@Mysql-server_2?~]#?cat?/data/3306/my.cnf
