rpm用法：
安裝 mysql-5.0.22-2.1.0.1.i386.rpm
# rpm -ivh mysql/*.rpm
啓動mysql服務：
# service mysqld start
查看mysql是否正常監聽3306端口：
# netstat -nat
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN
設置mysql默認用戶root的密碼：
# mysqladmin -u root -p password '123456'
以root用戶登陸mysql數據庫：
# mysql -u root -p
備份數據庫：
# mysqldump -u root -p --opt test>test.bak
導入備份：
# mysql -u root -p test<test.bak
遠程登陸mysql：
# mysql -u root -p -h 192.168.1.27

mysql官方tar.gz用法：
添加mysql系統用戶：
# groupadd mysql
# useradd -r -g mysql mysql
-r參數說明是系統用戶，不可登錄。系統用戶沒有用戶之家目錄，若非要用戶之家目錄，則再加-m參數。
解壓mysql-5.5.16-linux2.6-i686.tar.gz：
# cd /home/mysql
# tar -zxvf mysql-5.5.16-linux2.6-i686.tar.gz
# cd /home/mysql/mysql-5.5.16-linux2.6-i686
# chown -R mysql:mysql .
初始化數據庫（以mysql用戶身份生成權限表）：
# scripts/mysql_install_db --user=mysql
該步驟必須在mysql目錄中。
# chown -R root .
# chown -R mysql data
權限設置的最終結果爲，除了data文件夾屬於mysql用戶外，其它文件所有者都爲root。這樣保證了mysql用戶只有對數據庫操作的權限。
# ln -s /home/mysql/mysql-5.5.16-linux2.6-i686 /usr/local/mysql
啓動mysql：
# /usr/local/mysql/support-files/mysql.server start
推薦，但必須軟鏈接到/usr/local/mysql。
# bin/mysqld_safe --user=mysql &
該步驟必須在mysql目錄中執行，且停止mysql時要輸入密碼。
停止mysql：
# /usr/local/mysql/support-files/mysql.server stop
# /usr/local/mysql/bin/mysqladmin -u root -p shutdown
可選步驟：
# ln -s /home/mysql/mysql-5.5.16-linux2.6-i686/support-files/my-medium.cnf /etc/my.cnf
my.cnf是mysql的配置文件。
註冊mysql服務：
# ln -s /home/mysql/mysql-5.5.16-linux2.6-i686/support-files/mysql.server /etc/rc.d/init.d/mysql.server
開機啓用mysql服務：
# chkconfig --level 35 mysql.server on
#######################################################################################
我的用法：
解壓zxvf mysql-5.5.16-linux2.6-i686.tar.gz：
$ cd /home/mysql
$ tar -zxvf mysql-5.5.16-linux2.6-i686.tar.gz
初始化數據庫：
$ cd /home/mysql/mysql-5.5.16-linux2.6-i686
$ scripts/mysql_install_db
設置mysql目錄：
$ vi /home/mysql/mysql-5.5.16-linux2.6-i686/support-files/mysql.server
將第46行改爲：basedir=/home/mysql/mysql-5.5.16-linux2.6-i686
啓動mysql：
$ /home/mysql/mysql-5.5.16-linux2.6-i686/support-files/mysql.server start
設置root賬戶密碼：
$ /home/mysql/mysql-5.5.16-linux2.6-i686/bin/mysqladmin -u root -p password '123456'
以root賬戶登錄mysql：
$ /home/mysql/mysql-5.5.16-linux2.6-i686/bin/mysql -u root -p
停止mysql：
$ /home/mysql/mysql-5.5.16-linux2.6-i686/support-files/mysql.server stop
創建數據庫：
mysql> create database newdb;
導入腳本：
mysql> source /tmp/script.sql;
刪除數據庫：
mysql> drop database if exists newdb;

-h參數無法連接遠程mysql的問題：
登錄mysql，查詢mysql數據庫的user表
mysql> use mysql;
mysql> select * from user;

6 rows in set (0.00 sec)
就可以使用-h參數了。可見mysql與主機名息息相關。
