1、通过winscp上传MySQL5.6安装文件
2、判断一下服务器是否安装了MySQL
3、解压MySQL安装文件并进行重命名
[root@hadoop001 ~]# tar -zxvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@hadoop001 ~]# mysql-5.6.23-linux-glibc2.5-x86_64
4、创建用户和用户组
[root@hadoop001 ~]# groupadd -g 101 dba
[root@hadoop001 ~]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
[root@hadoop001 ~]# id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
[root@hadoop001 ~]# passwd mysqladmin
# copy 环境变量配置文件至mysqladmin用户的home目录中,为了以下步骤配置个人环境变量
[root@hadoop001 local]# cp /etc/skel/.* /usr/local/mysql
5、创建配置文件 /etc/my.cnf
[root@hadoop001 ~]# vi /etc/my.cnf
删除内容，并将以下内容复制进去

6、指定文件用户组、修改权限、尝试首次安装
[root@hadoop001 ~]# chown mysqladmin:dba /etc/my.cnf
[root@hadoop001 ~]# chmod 640 /etc/my.cnf
[root@hadoop001 ~]# ll /etc/my.cnf
-rw-r-----. 1 mysqladmin dba 2232 May 23 02:54 /etc/my.cnf
[root@hadoop001 ~]# chown -R mysqladmin:dba /usr/local/mysql
[root@hadoop001 ~]# chmod -R 755 /usr/local/mysql
[root@hadoop001 ~]# su - mysqladmin
[mysqladmin@hadoop001 ~]$ pwd
/usr/local/mysql
[mysqladmin@hadoop001 ~]$ mkdir arch
[mysqladmin@hadoop001 ~]$ scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
7、配置MySQL服务自己启动
[root@hadoop001 ~]# cd /usr/local/mysql
[root@hadoop001 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql
[root@hadoop001 mysql]# chmod +x /etc/rc.d/init.d/mysql
[root@hadoop001 mysql]# chkconfig --del mysql
[root@hadoop001 mysql]# chkconfig --add mysql
[root@hadoop001 mysql]# chkconfig --level 345 mysql on
8、查看进程
[root@hadoop001 mysql]# su - mysqladmin
[mysqladmin@localhost ~]$ pwd
/usr/local/mysql
[mysqladmin@localhost ~]$rm -rf my.cnf
[mysqladmin@localhost ~]$bin/mysqld_safe &
[mysqladmin@localhost ~]$ps -ef|grep mysqld
[mysqladmin@localhost ~]$netstat -tulnp | grep mysql
[mysqladmin@localhost ~]$service mysql status
9、登录MySQL
终端下输入mysql 回车进入
mysql -uroot -p 直接回车2次 root 空密码
