Centos MySQL5.6安裝方法，centosmysql5.6

Centos MySQL5.6安裝方法，centosmysql5.6

1. download rpm包

先確定系統版本

[root@xcldtc5m /]# cat /proc/version
Linux version 2.6.32-431.el6.x86_64 (mockbuild@c6b8.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) ) #1 SMP Fri Nov 22 03:15:09 UTC 2013

下載mysql rpm包

  wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.6/MySQL-server-5.6.22-1.el6.x86_64.rpm

  wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.6/MySQL-devel-5.6.22-1.el6.x86_64.rpm 
  wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.6/MySQL-client-5.6.22-1.el6.x86_64.rpm 

2. 安裝

[root@xcldtc5m mysql]# rpm -ivh MySQL-server-5.6.22-1.el6.x86_64.rpm

[root@xcldtc5m mysql]# rpm -ivh MySQL-devel-5.6.22-1.el6.x86_64.rpm

[root@xcldtc5m mysql]# rpm -ivh MySQL-client-5.6.22-1.el6.x86_64.rpm

發現缺libaio.so包
error: Failed dependencies:
        /usr/bin/perl is needed by MySQL-server-5.6.22-1.el6.x86_64
        libaio.so.1()(64bit) is needed by MySQL-server-5.6.22-1.el6.x86_64
        libaio.so.1(LIBAIO_0.1)(64bit) is needed by MySQL-server-5.6.22-1.el6.x86_64
        libaio.so.1(LIBAIO_0.4)(64bit) is needed by MySQL-server-5.6.22-1.el6.x86_64
error: Failed dependencies:
        /usr/bin/perl is needed by MySQL-server-5.6.22-1.el6.x86_64

解決方案

[root@xcldtc5m mysql]# yum install libaio

[root@xcldtc5m mysql]# yum install perl

若處理mysql版本衝突，先移除已經安裝的mysql

[root@xcldtc5m mysql]# yum -y remove mysql-libs-5.1.71*

3.修改設定檔位置

root@xcldtc5m mysql]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf 

4，初使化MYSQL及配置密碼

[root@xcldtc5m mysql]#  /usr/bin/mysql_install_db

[root@xcldtc5m mysql]# service mysql start

[root@xcldtc5m mysql]# cat /root/.mysql_secret
# The random password set for the root user at Sat Feb  7 10:54:24 2015 (local time): VoKvw3vpo_3LiA3c

[root@xcldtc5m mysql]# mysql -uroot -pVoKvw3vpo_3LiA3c

mysql>  SET PASSWORD = PASSWORD('2345678');

mysql> exit
[root@xcldtc5m mysql]# mysql -uroot -p2345678

5.遠程登入配置

mysql> use mysql

mysql> select host ,user ,password from user;
+-----------+------+-------------------------------------------+
| host      | user | password                                  |
+-----------+------+-------------------------------------------+
| localhost | root | *BC1C4715C23459AB982AD2D6617B4F8790161763 |
| xcldtc5m  | root | *44CF61DA6CDeeee2085F4598F728CF221DA8F167 |
| 127.0.0.1 | root | *44CF61DA6CD83e32085F4598F728CF221DA8F167 |
| ::1       | root | *44CF61DA6CD86832345F4598F728CF221DA8F167 |
+-----------+------+-------------------------------------------+

mysql> update user set password=password('234567') where user='root';

mysql> update user set host='%' where host='localhost';

6，設定開機自啟動

[root@xcldtc5m mysql]#  chkconfig mysql on
[root@xcldtc5m mysql]#  chkconfig --list | grep mysql
mysql           0:off   1:off   2:on    3:on    4:on    5:on    6:off

7，查看mysql設定檔位

[root@xcldtc5m mysql]# mysqld --verbose --help | grep -A 1 'Default options'

8，MYSQL預設安裝位置

1. /var/lib/mysql/               #資料庫目錄  
2. /usr/share/mysql              #設定檔目錄  
3. /usr/bin                     #相關命令目錄  
4. /etc/init.d/mysql              #啟動指令碼 
   

9，配置字元集

修改字元集和資料存放區路徑

配置/etc/my.cnf檔案,修改資料存放路徑、mysql.sock路徑以及預設編碼utf-8.
