HomeDatabaseMysql TutorialLinux下MySQL Install

1. 从http://www.mysql.com 下载的Mysql安装包 花开2.将mysql的压缩包复制到/usr/local/ 目录# cp mysql-standard-5.0.15-linux

1. 从 下载的Mysql安装包  花开

2.将mysql的压缩包复制到/usr/local/ 目录

# cp mysql-standard-5.0.15-linux-gnu-i686-glibc23.tar.gz /usr/local

3. 解压缩到/usr/ocal/下并改名为mysql,并为了节省空间,删除mysql安装包

# tar xzvf mysql-standard-5.0.15-linux-gnu-i686-glibc23.tar.gz

# mv mysql-standard-5.0.15-linux-gnu-i686-glibc23 mysql

# rm mysql-standard-5.0.15-linux-gnu-i686-glibc23

4.建立mysql组,建立mysql用户并且加入到mysql组中

# groupadd mysql

# useradd mysql -g mysql

5. 覆盖/etc/my.cnf

# cp /usr/local/mysql/support-files/my-medium.cnf /etc/my.cnf

6. 进入mysql目录初试化表并且规定用mysql用户来访问。初始化表以后就开始给mysql和root用户设定访问权限

# cd /usr/local/mysql

# ./scripts/mysql_install_db --user=mysql

7. 设定root能访问/usr/local/mysql

# chown -R root .

8. 设定mysql用户能访问/usr/local/mysql/data ,里面存的是mysql的数据库文件.这个目录是在/etc/my.cnf中有配置,,在mysql_install_db时产生

# chown -R mysql data

9. 设定mysql用户能访问/usr/local/mysql/data/mysql下的所有文件

# chown -R mysql data/.

10.设定mysql组能够访问/usr/local/mysql

# chgrp -R mysql .

11. 运行mysql,如果没有问题的话,应该会出现类似这样的提示:

[1] 42264

Starting mysqld daemon with databases from /usr/local/mysql/var

# /usr/local/mysql/bin/mysqld_safe --user=mysql &

如果出现 mysql ended这样的语句,表示Mysql没有正常启动,你可以到log中查找问题,Log文件的通常在/etc/my.cnf中配置。大多数问题是权限设置不正确引起的。

12. 用如下命令修改MYSQL密

# /usr/local/mysql/bin/mysqladmin -u root password yourpassword

13. copy编译目录的一个脚本,设置使mysql每次启动都能自动运行

# cp support-files/mysql.server /etc/rc.d/init.d/mysqld

# chmod 700 /etc/init.d/mysqld

# chkconfig --add mysqld

# chkconfig --level 345 mysqld on

14. 启动mysqld服务 拥抱

# service mysqld start
