以下内容转载自网络，因我自己操作过程中，有报错，所以汇总整理一下：
1.检查MySQL及相关RPM包，是否安装，如果有安装，则移除（rpm –e 名称）
[root@localhost ~]#rpm -qa | grep -i mysql mysql-libs-5.1.66-2.el6_3.x86_64 [root@localhost ~]#rpm -e mysql-libs-5.1.66-2.el6_3.x86_64 --nodeps
2. 下载Linux对应的RPM包，如Rethat6对应的RPM包如下：
[root@localhost RPM]# ll total 458596 -rw-r--r-- 1 root root 18724760 May 6 19:27 MySQL-client-advanced-5.6.25-1.el6.x86_64.rpm -rw-r--r-- 1 root root 3327796 May 6 19:27 MySQL-devel-advanced-5.6.25-1.el6.x86_64.rpm -rw-r--r-- 1 root root 89610660 May 6 19:28 MySQL-embedded-advanced-5.6.25-1.el6.x86_64.rpm -rw-r--r-- 1 root root 65951124 May 6 19:29 MySQL-server-advanced-5.6.25-1.el6.x86_64.rpm -rw-r--r-- 1 root root 2031032 May 6 19:29 MySQL-shared-advanced-5.6.25-1.el6.x86_64.rpm -rw-r--r-- 1 root root 3945172 May 6 19:29 MySQL-shared-compat-advanced-5.6.25-1.el6.x86_64.rpm -rw-r--r-- 1 root root 51185604 May 6 19:30 MySQL-test-advanced-5.6.25-1.el6.x86_64.rpm -rw-r--r-- 1 root root 15602 May 28 19:30 README.txt -rw------- 1 ntsj ftp 234793042 Jul 31 15:30 V76360-01.zip
3.安装MySQL
[root@localhost rpm]# rpm -ivh MySQL-server-advanced-5.6.25-1.el6.x86_64.rpm [root@localhost rpm]# rpm -ivh MySQL-devel-advanced-5.6.25-1.el6.x86_64.rpm [root@localhost rpm]# rpm -ivh MySQL-client-advanced-5.6.25-1.el6.x86_64.rpm #修改配置文件位置 [root@localhost rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf
4.初始化MySQL及设置密码
[root@localhost bin]# /usr/bin/mysql_install_db
[root@localhost bin]# service mysql start
[root@localhost bin]#mysql -uroot –p
mysql> SET PASSWORD = PASSWORD('123456'); #设置密码为123456
mysql> exit
[root@localhost ~]# mysql -uroot -p123456
我在这里启动Mysql服务的时候报错，如下：
Can't open the mysql.plugin table. Please run mysql_upgrade to create it.
后边还有一大串，就不全粘贴在这里了，解决方法如下：
在运行初始化权限表的时候使用增加参数--datadir ，命令格式为：
shell> /usr/bin/mysql_install_db --user=mysql --datadir=/data/mysql/var
5.允许远程登录
mysql> use mysql;
mysql> select host,user,password from user;
+-----------------------+------+-------------------------------------------+
| host | user | password |
+-----------------------+------+-------------------------------------------+
| localhost | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
| localhost.localdomain | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |
| 127.0.0.1 | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |
| ::1 | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |
+-----------------------+------+-------------------------------------------+
mysql> update user set password=password('123456') where user='root';
mysql> update user set host='%' where user='root' and host='localhost';
mysql> flush privileges;
mysql> exit
6.设置开机自动启动
[root@localhost ~]# chkconfig mysql on [root@localhost ~]# chkconfig --list | grep mysql mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off
7.MySQL的默认安装路径
/var/lib/mysql/ #数据库目录 /usr/share/mysql #配置文件目录 /usr/bin #相关命令目录 /etc/init.d/mysql #启动脚本
我上边已经改了数据库目录了，改到/data/mysql/var了。
8.修改字符集和数据存储路径
配置/etc/my.cnf文件,修改数据存放路径、mysql.sock路径以及默认编码utf-8。
[client] password = 123456 port = 3306 default-character-set=utf8 [mysqld] port = 3306 character_set_server=utf8 character_set_client=utf8 collation-server=utf8_general_ci datadir = /data/mysql/var #(注意linux下mysql安装完后是默认：表名区分大小写，列名不区分大小写； 0：区分大小写，1：不区分大小写) lower_case_table_names=1 #(设置最大连接数，默认为 151，MySQL服务器允许的最大连接数16384; ) max_connections=1000 [mysql] default-character-set = utf8
9.查看字符集
show variables like '%collation%'; show variables like '%char%';
