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 ~]# yum -y remove mysql-libs*
2，删除掉系统中原有的数据，不然可以导致错误，我实际安装过程中试了几个小时，如果还有错，请参考
mv /var/lib/mysql /var/lib/mysql_old

2，下载Linux对应的RPM包，如：CentOS6.4_32对应的RPM包，如下：
-rwxr--r--. 1 nobody nobody 22838580 Mar 17 17:39 MySQL-client-5.6.17-1.linux_glibc2.5.i386.rpm -rwxr--r--. 1 nobody nobody 4135464 Mar 17 17:40 MySQL-devel-5.6.17-1.linux_glibc2.5.i386.rpm -rwxr--r--. 1 nobody nobody 109826437 Mar 17 17:40 MySQL-embedded-5.6.17-1.linux_glibc2.5.i386.rpm -rwxr--r--. 1 nobody nobody 87469456 Mar 17 17:41 MySQL-server-5.6.17-1.linux_glibc2.5.i386.rpm -rwxr--r--. 1 nobody nobody 2362688 Mar 17 17:41 MySQL-shared-5.6.17-1.linux_glibc2.5.i386.rpm -rwxr--r--. 1 nobody nobody 5294221 Mar 17 17:41 MySQL-shared-compat-5.6.17-1.linux_glibc2.5.i386.rpm -rwxr--r--. 1 nobody nobody 74163863 Mar 17 17:41 MySQL-test-5.6.17-1.linux_glibc2.5.i386.rpm
3， 安装mysl
[root@localhost rpm]# rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm [root@localhost rpm]# rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm [root@localhost rpm]# rpm -ivh MySQL-client-5.6.15-1.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，初使化MYSQL及配置密码
[root@localhost rpm]# /usr/bin/mysql_install_db [root@localhost rpm]# service mysql start [root@localhost rpm]# cat /root/.mysql_secret #查看root账号密码 # The random password set for the root user at Wed Dec 11 23:32:50 2013 (local time): qKTaFZnl [root@localhost ~]# mysql -uroot –pqKTaFZnl mysql> SET PASSWORD = PASSWORD(‘123456‘); #设置密码为123456 mysql> exit [root@localhost ~]# mysql -uroot -p123456
5，允许远程登录
mysql> use mysql; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> select host,user,password from user; +-----------------------+------+-------------------------------------------+ | host | user | password | +-----------------------+------+-------------------------------------------+ | localhost | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B | | localhost.localdomain | root | *A4B8196FF869F64E0119B231785E5946EDBA5E26 | | 127.0.0.1 | root | *A4B8196FF869F64E0119B231785E5946EDBA5E26 | | ::1 | root | *A4B8196FF869F64E0119B231785E5946EDBA5E26 | +-----------------------+------+-------------------------------------------+ 4 rows in set (0.00 sec) mysql> update user set password=password(‘root‘) where user=‘root‘; Query OK, 3 rows affected (0.01 sec) Rows matched: 4 Changed: 3 Warnings: 0 mysql> update user set host=‘%‘ where user=‘root‘ and host=‘localhost‘; Query OK, 1 row affected (0.04 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)
6，设置开机自启动
[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，查看mysql配置文件位置
mysqld --verbose --help | grep -A 1 ‘Default options‘
8，MYSQL默认安装位置
/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
9，配置字符集
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 #(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
查看字符集
show variables like ‘%collation%‘;
show variables like ‘%char%‘;
