安裝步驟

1、下載（32位）安裝包mysql-5.1.60-linux-i686-glibc23.tar.gz

2、創建用戶和用戶組

shell> groupadd mysql
shell> useradd -r -g mysql mysql

3、解壓安裝包安裝包mysql-5.1.60-linux-i686-glibc23.tar.gz

shell> cd /usr/local
shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz

4、做軟連接

ln -s full-path-to-mysql-VERSION-OS mysql

5、修改安裝目錄權限

shell> chown -R mysql:mysql .

6、運行腳本creates the MySQL Server system tables

scripts/mysql_install_db --user=mysql

腳本會根據/usr/local/mysql/share/mysql_system_tables.sql創建系統表，如果不運行的話沒有host表，是不能登陸mysql服務的

7、修改目錄權限

shell> chown -R root .
shell> chown -R mysql data

8、修改配置文件（可選）

# Next command is optional
shell> cp support-files/my-medium.cnf /etc/my.cnf

9、運行啓動mysql

shell> bin/mysqld_safe --user=mysql &

 

10、添加到系統服務中（可以通過service ServiceName start/stop/restart來啓停服務）

# Next command is optional
shell> cp support-files/mysql.server /etc/init.d/mysqld

 

11、添加開機自啓動

# Next command is optional
shell> chkconfig mysqld on

 

mysql.server腳本主要通過調用腳本bin/mysqld_safe來啓動mysql數據庫
