檢查是否已安裝
[root@hadoop-01 local]# ps -ef|grep mysqld
解壓重命名
[root@hadoop-01 local]# tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@hadoop-01 local]# mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql
創(chuàng)建用戶組
[root@hadoop-01 local]# groupadd -g 101 dba
[root@hadoop-01 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
[root@hadoop-01 local]# id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
[root@hadoop-01 local]# passwd mysqladmin
# copy 環(huán)境變量配置文件至 mysqladmin 用戶的 home 目錄中, 為了以下步驟配置個(gè)人環(huán)境變量
[root@hadoop-01 local]# cp /etc/skel/.* /usr/local/mysql
創(chuàng)建配置文件 /etc/my.cnf(640)
[root@hadoop-01 mysql]# vi /etc/my.cnf
