一、环境与下载地址：
1、系统下载地址：
http://mirrors.sohu.com/centos/6.6/isos/x86_64/CentOS-6.6-x86_64-bin-DVD1.iso
2、mysql下载地址：
推荐使用官方
二、安装mysql的步骤：
1、卸载原版本的mysql：
yum -y remove mysql-libs-5.1*
或者
rpm -e 原始mysql
2、创建一个MySQL用户组：
groupadd mysql
3、一个属于MySQL的用组的mysql用户
useradd -g mysql -s /sbin/nologin -d /opt/mysql mysql
4、查看用户和组状态：
id mysql
uid=500(mysql) gid=500(mysql) groups=500(mysql)
5、配置myql的安装目录：
mkdir -p /opt/mysql/mysql-5.6.22
mkdir -p /data/mysql/mysql_3306/{data,tmp,logs}
ln -s /opt/mysql/mysql-5.6.22 /usr/local/mysql
ll /usr/local/
6、查看结果：
ll /usr/local/
lrwxrwxrwx 1 root root 23 Dec 17 15:24 mysql -> /opt/mysql/mysql-5.6.22
7、解压mysql的安装包：
tar -xzvf /data/soft/mysql-5.6.22-linux-glibc2.5-x86_64.tar.gz -C /opt/mysql/mysql-5.6.22/
8、剪贴文件到安装目录：
cd /opt/mysql/mysql-5.6.22
mv mysql-5.6.22-linux-glibc2.5-x86_64/* .
9、查看依赖的lib库是否安全
ldd /usr/local/mysql/bin/mysqld
10、更改权限：
chown -R mysql:mysql /usr/local/mysql/
chown -R mysql:mysql /data/mysql/
chown -R mysql:mysql /opt/mysql/
11、设置root的环境变量：
vi .bash_profile
export PATH=/usr/local/mysql/bin:/opt/mysql/mysql-5.6.22/bin:$HOME/bin:$PATH
source .bash_profile
12、编辑my.cnf
#my.cnf[client]port = 3306socket = /tmp/mysql.sock [mysql]prompt=[master]>#pager="less -i -n -S"tee=/data/mysql/mysql_3306/data/query.logno-auto-rehash [mysqld_multi]mysqld = /usr/local/mysql/bin/mysqld_safemysqladmin = /usr/local/mysql/bin/mysqladminlog = /opt/mysql/mysqld_multi.log [mysqld]#miscexplicit_defaults_for_timestamp = ture

cp my.cnf /etc/my.cnf
14、初始化数据库：
cd /usr/local/mysql/
初始化数据库一定要在basedir 下进行
./scripts/mysql_install_db --user=mysql --defaults-file=/etc/my.cnf
15、将启动信息加入到启动像
cd /usr/local/mysql
cp support-files/mysql.server /etc/init.d/mysql
16、启动mysql服务：
/etc/init.d/mysql start
17、查看mysql是否启动成功：
a、查看mysql的进程：
ps axu|grep mysqld
b、查看mysql的监听：
netstat -nalp|grep "3306"
18、添加启动项：
chkconfig --add mysql
chkconfig --level 35 mysql on
chkconfig --list |grep mysql
mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off
19、查看mysql用户的表信息：
select user,host,password from mysql.user;
+------+-----------+----------+
| user | host | password |
+------+-----------+----------+
| root | localhost | |
| root | master1 | |
| root | 127.0.0.1 | |
| root | ::1 | |
| | localhost | |
| | master1 | |
+------+-----------+----------+
6 rows in set (0.00 sec)
20、删除初始化用户：
delete from mysql.user where user!=‘root‘ or host!=‘localhost‘;
21、刷新数据库：
flush privileges;
22、检查权限：
select user,host,password from mysql.user;
=========================================================
安装时出现的问题大多数的排错思路如下：
1、初始化mysql的时候，需要开启另一个连接，tail -f error.log，根据报错进行查看。
2、查看my.cnf文件里的目录是否都存在。
3、查看my.cnf文件里的目录权限是否都是mysql.mysql。
4、如果是虚拟机查看内存和磁盘是否足够。
