Centos MySQL5.6安裝方法
1. download rpm包
先確定系統版本
[[email protected] /]# cat /proc/version
Linux version 2.6.32-431.el6.x86_64 ([email protected]) (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
[[email protected] mysql]# rpm -ivh MySQL-server-5.6.22-1.el6.x86_64.rpm
[[email protected] mysql]# rpm -ivh MySQL-devel-5.6.22-1.el6.x86_64.rpm
[[email protected] 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
解決方法
[[email protected] mysql]# yum install libaio
[[email protected] mysql]# yum install perl
若處理mysql版本衝突,先移除已經安裝的mysql
[[email protected] mysql]# yum -y remove mysql-libs-5.1.71*
3.修改配置檔案位置
[email protected] mysql]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf
4,初使化MYSQL及配置密碼
[[email protected] mysql]# /usr/bin/mysql_install_db
[[email protected] mysql]# service mysql start
[[email protected] 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
[[email protected] mysql]# mysql -uroot -pVoKvw3vpo_3LiA3c
mysql> SET PASSWORD = PASSWORD('2345678');
mysql> exit
[[email protected] mysql]# mysql -uroot -p2345678
5.遠端登入配置
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
[[email protected] mysql]# chkconfig mysql on
[[email protected] mysql]# chkconfig --list | grep mysql
mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off
7,檢視mysql配置檔案位
[[email protected] mysql]# mysqld --verbose --help | grep -A 1 'Default options'
8,MYSQL預設安裝位置
- /var/lib/mysql/ #資料庫目錄
- /usr/share/mysql #配置檔案目錄
- /usr/bin #相關命令目錄
- /etc/init.d/mysql #啟動指令碼
9,配置字符集
修改字符集和資料儲存路徑
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.
