检查是否已经安装mysql

rpm -qa| grep mysql

[root@test /]# rpm -qa | grep mysql 
mysql-libs-5.1.71-1.el6.x86_64

卸载mysql

rpm -e mysql-libs –nodeps

在电脑中查找有关mysql的文件尽可能删掉,如果有的话 
比如/etc/my.cc或者/etc/mysql

下载及解压安装包 
官方下载地址为:http://dev.mysql.com/downloads/mysql/ 
Linux - Generic 
(mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz)

我的安装目录是: /home/mysql

#安装libaio库
yum search libaio  
yum install libaio 
#移动mysql更目录到需要安装的地方
cd /home/setup/clear
tar -zxvf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz
mv /home/setup/mysql-5.7.17-linux-glibc2.5-x86_64 /home/mysql
#复制配置文件
cp /home/mysql/support-files/my-default.cnf /etc/my.cnf
#修改配置文件 修改内容如下
vi /etc/my.cnf 
basedir = /home/mysql/
datadir = /home/mysql/data
port = 3306
socket = /home/mysql/tmp/mysql.sock
#创建data,tmp目录
cd /home/mysql
mkdir data
mkdir tmp
#创建不可登陆用户及组
groupadd  mysql
useradd -r -g mysql -s /bin/false mysql 
#增加目录权限
cd /home/mysql
chown -R mysql .
chgrp -R mysql .

#复制mysqld
cp /home/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld

#初始化数据库
cd /home/mysql/bin
./mysqld --user=mysql --basedir=/home/mysql --datadir=/home/mysql/data --initialize
[Note] A temporary password is generated for root@localhost: b,prkho.N8Sm
#需要注意关于timestamp的设置--explicit_defaults_for_timestamp

#启动
service mysqld start
#如果报如下错误:则需要转到NEXT1
[root@test bin]# service mysqld start
