[root@lnmp02 tools]# tar zxvfmysql-5.5.32-linux2.6-x86_64.tar.gz

[root@lnmp02 tools]# mvmysql-5.5.32-linux2.6-x86_64  /application/mysql-5.5.32

[root@lnmp02 tools]# ln -s/application/mysql-5.5.32  /application/mysql

OK

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啟動腳本里的路徑

[root@lnmp02 ~]# chown -Rmysql.mysql /application/mysql/

[root@lnmp02 ~]# cp /application/mysql/support-files/my-small.cnf /etc/my.cnf

[root@lnmp02 ~]# sed -i's#/usr/local/mysql#/application/mysql#g' /application/mysql/bin/mysqld_safe     ###修改腳本里的安裝路徑

[root@lnmp02 ~]#/application/mysql/bin/mysqld_safe &  ###以后臺進程方式啟動MySQL

1. 查看MySQL是否正常啟動

[root@lnmp02 ~]# lsof -i:3306

[root@lnmp02 ~]# netstat-tulpn|grep 3306

[root@lnmp02 ~]# ps -ef|grepmysql

1. 配置環境變量

[root@lnmp02 ~]# echo"PATH=/application/mysql/bin:$PATH" >>/etc/profile

[root@lnmp02 ~]# source/etc/profile

[root@lnmp02 ~]# 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

[root@lnmp02 ~]# mysql

1. 配置傳統方式啟動MySQL

[root@lnmp02 ~]# cp/application/mysql/support-files/mysql.server /etc/init.d/mysqld

[root@lnmp02 ~]# sed -i's#/usr/local/mysql#/application/mysql#g' /etc/init.d/mysqld  ##修改mysql安裝路徑

[root@lnmp02 ~]# killall mysqld   ###殺死之前啟動的mysql進程

[root@lnmp02 ~]# lsof -i:3306    ###確認是否已殺死mysql進程

[root@lnmp02 ~]#/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

[root@lnmp02 ~]# mysqladmin-uroot password "123456"

[root@lnmp02 ~]# mysql -uroot-p123456   ###登陸mysql，注意，-p和密碼之間不能有空格

[root@lnmp02 ~]# mysqladmin-uroot -p123456 password "wangning" ###更改密碼

1. 查看錯誤日志

[root@lnmp02 ~]# cat  /application/mysql/data/lnmp02.err    ###該錯誤日志文件是以主機名加.err后綴命名的
