Centos6.5 MySql rpm安装

转载请出自出处:http://eksliang.iteye.com/blog/2298702

一、检查MySQL及相关RPM包,是否安装,如果有安装,则移除

 

[root@Mast ~]# rpm -qa | grep -i mysql
mysql-libs-5.1.66-2.el6_3.x86_64
#卸载的时候可能存在依赖包,直接 -ev还删除不掉,需加上--nodeps 强制删除
[root@Mast ~]# rpm -ev mysql-libs-5.1.66-2.el6_3.x86_64
error: Failed dependencies:
        libmysqlclient.so.16()(64bit) is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64
        libmysqlclient.so.16(libmysqlclient_16)(64bit) is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64
        mysql-libs is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64
[root@Mast ~]# rpm -ev mysql-libs-5.1.66-2.el6_3.x86_64 --nodeps

 

 

二、下载Linux对应的RPM包

官方下载地址:http://dev.mysql.com/downloads/mysql/  选择MySql Community Service(社区版进行下载)

我的是centos6.5 x86的系统,所以的下载包如下所示

 

[root@Mast data]# uname -a
Linux Mast 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
[root@Mast data]# ls -l
total 115360
-rw-r--r--. 1 root root 23495271  MySQL-client-5.6.30-1.linux_glibc2.5.x86_64.rpm
-rw-r--r--. 1 root root  4591071  MySQL-devel-5.6.30-1.linux_glibc2.5.x86_64.rpm
-rw-r--r--. 1 root root 90037444  MySQL-server-5.6.30-1.linux_glibc2.5.x86_64.rpm

 

 

三、安装MySQL

 

[root@Mast data]# rpm -ivh MySQL-server-5.6.30-1.linux_glibc2.5.x86_64.rpm 
[root@Mast data]# rpm -ivh MySQL-devel-5.6.30-1.linux_glibc2.5.x86_64.rpm 
[root@Mast data]# rpm -ivh MySQL-client-5.6.30-1.linux_glibc2.5.x86_64.rpm

 

 

四、初始化MySQL及设置密码

 

[root@Mast ~]# /usr/bin/mysql_install_db #初始化数据库
[root@Mast ~]# service mysql start       #启动数据库
[root@Mast ~]# cat /root/.mysql_secret   #查看root用户的初始密码
# The random password set for the root user at Mon May 16 19:31:48 2016 (local time): DXaM9aqT62DxVUcv
[root@localhost ~]# mysql -uroot –p
mysql> SET PASSWORD = PASSWORD('123456');    #设置密码为123456
mysql> exit
[root@localhost ~]# mysql -uroot -p

 

 

五、允许远程登录

 

mysql> use mysql;
mysql> select host,user,password from user;
+-----------------------+------+-------------------------------------------+
04
| 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

 

 

六、设置开机自启动

 

[root@Mast data]# chkconfig mysql on
[root@Mast data]# chkconfig --list mysql
mysql           0:off   1:off   2:on    3:on    4:on    5:on    6:off
[root@Mast data]# 

 

 

七、修改字符集

查看linux系统的字符集

 

mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+------------------------------------+
| Variable_name            | Value                              |
+--------------------------+------------------------------------+
| character_set_client     | utf8                               |
| character_set_connection | utf8                               |
| character_set_database   | latin1                             |
| character_set_filesystem | binary                             |
| character_set_results    | utf8                               |
| character_set_server     | latin1                             |
| character_set_system     | utf8                               |
| character_sets_dir       | /data/mysql-5.6.30/share/charsets/ |
+--------------------------+------------------------------------+

 可以看到character_set_database和character_set_server的默认字符集还是latin1,配置/etc/my.cnf文件,加入如下代码,重启后,完美解决

 

[client]
default-character-set=utf8
[mysqld]
character-set-server=utf8
[mysql]
default-character-set=utf8

 每个版本的mysql这个文件的默认配置不一定相同,加入原则就是:

在[client] 后面加上default-character-set=utf8

在[mysqld]后面加上character-set-server=utf8

在[mysql]后面加上default-character-set=utf8

 

 

 

八、MySQL的默认安装位置

 

/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
