下載mysql并檢查MD5

[root@hadoop-01 ~]# cd /usr/local
[root@hadoop-01 local]# wget https://downloads.mariadb.com/archives/mysql-5.6/mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@hadoop-01 local]# wget https://downloads.mariadb.com/archives/mysql-5.6/mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz.md5

[root@hadoop-01 local]# vi mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz.md5
61affe944eff55fcf51b31e67f25dc10  mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

[root@hadoop-01 local]# md5sum mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
61affe944eff55fcf51b31e67f25dc10  mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

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

[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
