To start mysqld at boot timeyou have to copy

support-files/mysql.server tothe right place for your system

PLEASE REMEMBER TO SET APASSWORD FOR THE MySQL root USER !

To do so, start the server,then issue the following commands:

/application/mysql//bin/mysqladmin-u root password ‘new-password‘

/application/mysql//bin/mysqladmin-u root -h lnmp02 password ‘new-password‘

Alternatively you can run:

/application/mysql//bin/mysql_secure_installation

which will also give you theoption of removing the test

databases and anonymous usercreated by default. This is

strongly recommended forproduction servers.

See the manual for moreinstructions.

You can start the MySQL daemonwith:

cd /application/mysql/ ;/application/mysql//bin/mysqld_safe &

You can test the MySQL daemonwith mysql-test-run.pl

cd/application/mysql//mysql-test ; perl mysql-test-run.pl

Please report any problems withthe /application/mysql//scripts/mysqlbug script!

1. 改變/application/mysql所屬主和組，cp配置文件，改變MySQL啟動腳本裏的路徑

[[email protected] ~]# chown -Rmysql.mysql /application/mysql/

[[email protected] ~]# cp /application/mysql/support-files/my-small.cnf /etc/my.cnf

[[email protected] ~]# sed -i‘s#/usr/local/mysql#/application/mysql#g‘ /application/mysql/bin/mysqld_safe ###修改腳本裏的安裝路徑

[[email protected] ~]#/application/mysql/bin/mysqld_safe & ###以後臺進程方式啟動MySQL

1. 查看MySQL是否正常啟動

[[email protected] ~]# lsof -i:3306

[[email protected] ~]# netstat-tulpn|grep 3306

[[email protected] ~]# ps -ef|grepmysql

1. 配置環境變量

[[email protected] ~]# echo"PATH=/application/mysql/bin:$PATH" >>/etc/profile

[[email protected] ~]# source/etc/profile

[[email protected] ~]# which mysql ###確定是否是綠色版的MySQL而不是yum安裝的MySQL

/application/mysql/bin/mysql

1. 登陸MySQL

[[email protected] ~]# mysql

[[email protected] ~]# cp/application/mysql/support-files/mysql.server /etc/init.d/mysqld

[[email protected] ~]# sed -i‘s#/usr/local/mysql#/application/mysql#g‘ /etc/init.d/mysqld ##修改mysql安裝路徑

[[email protected] ~]# killall mysqld ###殺死之前啟動的mysql進程

[[email protected] ~]# lsof -i:3306 ###確認是否已殺死mysql進程

[[email protected] ~]#/etc/init.d/mysqld start ###以傳統方式重新啟動mysql進程

1. 設置mysql管理員密碼，默認管理員是root用戶

[[email protected] ~]# mysqladmin-uroot password "123456"

[[email protected] ~]# mysql -uroot-p123456 ###登陸mysql，註意，-p和密碼之間不能有空格

[[email protected] ~]# mysqladmin-uroot -p123456 password "wangning" ###更改密碼

1. 查看錯誤日誌

[[email protected] ~]# cat /application/mysql/data/lnmp02.err ###該錯誤日誌文件是以主機名加.err後綴命名的
