1.前言

本文測試環境：

• CentOS release 6.4（Linux version 2.6.32-358.el6.x86_64）

• MySQL-5.6.26 RPM包下載地址：http://dev.mysql.com/downloads/mysql/，相關的文件參詳：http://dev.mysql.com/doc/refman/5.7/en/linux-installation-rpm.html。

• MySQL社群版對應的RPM包如下：

Package Name	Summary
mysql-community-server	Database server and related tools
mysql-community-client	MySQL client applications and tools
mysql-community-common	Common files for server and client libraries
mysql-community-devel	Development header files and libraries for MySQL database client applications
mysql-community-libs	Shared libraries for MySQL database client applications
mysql-community-libs-compat	Shared compatibility libraries for previous MySQL installations
mysql-community-embedded	MySQL embedded library
mysql-community-embedded-devel	Development header files and libraries for MySQL as an embeddable library
mysql-community-test	Test suite for the MySQL server

2.安裝前準備

1）檢查MySQL

及相關RPM包，是否安裝，如果有安裝，則移除（rpm–e名稱）

[[email protected] ~]# rpm -qa | grep -i mysql

[[email protected] ~]# yum -y remove mysql-libs*

2）下載Linux對應的RPM包，如：CentOS6.4_64對應的RPM包，本文已在官網下載，這裡就不詳敘了。

3）MySQL預設安裝路徑

Directory	Contents of Directory
/usr/bin	Client programs and scripts
/usr/sbin	The mysqld server
/var/lib/mysql	Log files, databases
/usr/share/info	Manual in Info format
/usr/share/man	Unix manual pages
/usr/include/mysql	Include (header) files
/usr/lib/mysql	Libraries
/usr/share/mysql	Miscellaneous support files, including error messages, character set files, sample configuration files, SQL for database installation
/usr/share/sql-bench	Benchmarks

3.安裝MySQL

[[email protected] ~]# cd /home/MySql/MySQL-5.6.26-1.linux_glibc2.5.x86_64.rpm-bundle/

[[email protected] MySQL-5.6.26-1.linux_glibc2.5.x86_64.rpm-bundle]# rpm -ivh MySQL-server-5.6.26-1.linux_glibc2.5.x86_64.rpm

[[email protected] MySQL-5.6.26-1.linux_glibc2.5.x86_64.rpm-bundle]# rpm -ivh MySQL-client-5.6.26-1.linux_glibc2.5.x86_64.rpm

4.初始化MySQL及密碼

[[email protected] ~]# service mysql start

[[email protected] ~]# more /root/.mysql_secret

[[email protected] ~]# mysql -u root -p

mysql> set PASSWORD=PASSWORD('123456');

5.允許遠端登陸

mysql> use mysql;

mysql> select host,user,password from user;

mysql> update user set password=password('123456') where user='root';

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

mysql> flush privileges;

6. 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。

[[email protected] ~]# cp /usr/my.cnf /etc/my.cnf

7.設定開機自啟動

[[email protected] ~]# chkconfig mysql on

[[email protected] ~]# chkconfig --list | grep mysql

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT option;

         該SQL的作用是將所有的使用者名稱，都設定能遠端訪問該mysql中所有的表，如果不想都放開，可以根據這個規則，來設定.grant許可權1，許可權2，…許可權n on資料庫名.表名to使用者名稱@使用者地址identified by‘口令’。
