这篇文章主要介绍“CentOS6.5下MySQL5.6的安装过程”，在日常操作中，相信很多人在CentOS6.5下MySQL5.6的安装过程问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答”CentOS6.5下MySQL5.6的安装过程”的疑惑有所帮助！接下来，请跟着小编一起来学习吧！
1.切换到/usr/local目录下，上传MySQL的tar包
[root@hadoop001 ~]# cd /usr/local
[root@hadoopnn001 local]# rz
2.检查是否安装过
[root@hadoop001 local]# ps -ef|grep mysqld
root 2493 2423 0 19:48 pts/3 00:00:00 grep mysqld
[root@hadoop0 01 local]# rpm -qa |grep -i mysql
3.解压复制
[root@hadoop001 local]# tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@hadoopnn001 local]# mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql
4.创建用户组和用户
[root@hadoop001 local]# groupadd -g 101 dba
[root@hadoop001 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
[root@hadoop001 local]# id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
[root@hadoop001 local]# passwd mysqladmin
Changing password for user mysqladmin.
New UNIX password:
BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
5.修改用户的执行权限
[root@hadoop001 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
6.配置个人环境变量（copy 环境变量配置文件至mysqladmin用户的home目录中）
[root@hadoop001 local]# cp /etc/skel/.* /usr/local/mysql
cp: omitting directory `/etc/skel/.'
cp: omitting directory `/etc/skel/..'
cp: omitting directory `/etc/skel/.mozilla'
7.vi /etc/my.cnf ,把下列内容复制进去
(默认： /etc/my.cnf->/etc/mysql/my.cnf->SYSCONFDIR/my.cnf->$MYSQL_HOME/my.cnf-> --defaults-extra-file->~/my.cnf )
[root@hadoop001 ~]# vi /etc/my.cnf

[root@hadoop001 local]# su - mysqladmin
[mysqladmin@hadoop001 ~]$ pwd
/usr/local/mysql
[mysqladmin@hadoop001 ~]$ mkdir arch
8.第一次安装

10.配置mysql服务和部署自动启动
[root@hadoop001 ~]# cd /usr/local/mysql
#将服务文件拷贝到init.d下，并重命名为mysql
[root@hadoop001 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql
#赋予可执行权限
[root@hadoop001 mysql]# chmod +x /etc/rc.d/init.d/mysql
#删除服务
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --del mysql
#添加服务
[root@0hadoop001 mysql]# chkconfig --add mysql
[root@hadoop001 mysql]# chkconfig --level 345 mysql on
11.Start mysql and to view process and listening
[root@hadoop001 mysql]# su - mysqladmin
[mysqladmin@hadoop001 ~]$ pwd
/usr/local/mysql
[mysqladmin@hadoop001 ~]$ rm -rf my.cnf
[mysqladmin@sht-sgmhadoopnn-01 ~]$ bin/mysqld_safe &
先卸载
[root@rzdatahadoop001 lib]# rpm --nodeps -e mysql-libs-5.1.71-1.el6.x86_64
改权限
[root@rzdatahadoop001 mysql]# chmod -R 757 /var/log
