Thank you for choosing MySQL!

 

Remember to check the platform specific part of the reference manual

for hints about installing MySQL on your platform.

Also have a look at the files in the Docs directory.

[root@localhost mysql-5.1.72]# echo $?

0

[root@localhost mysql-5.1.72]# make && make install

[root@localhost mysql-5.1.72]# ln -s /application/ mysql-5.1.72 / /application/mysql

如果mysql和web服务器不在同一台机器，到上面步骤，安装完毕数据库！！

如果在同一台机器上，就接着执行如下步骤。

 

[root@localhost support-files]# pwd

/home/oldboy/tools/mysql-5.1.72/support-files

[root@localhost support-files]#

[root@moban support-files]#  ll my-*.cnf

-rw-r--r--. 1 root root  4746 May 25 22:59 my-huge.cnf

-rw-r--r--. 1 root root 19779 May 25 22:59 my-innodb-heavy-4G.cnf

-rw-r--r--. 1 root root  4720 May 25 22:59 my-large.cnf

-rw-r--r--. 1 root root  4731 May 25 22:59 my-medium.cnf

-rw-r--r--. 1 root root  2499 May 25 22:59 my-small.cnf

[root@localhost support-files]# cp my-small.cnf  /etc/my.cnf  （初始化数据库配置文件）

创建mysql数据文件目录

[root@localhost support-files]# mkdir /application/mysql/data -p

[root@localhost support-files]# chown -R mysql.mysql /application/mysql/

数据库初始化

[root@localhost support-files]# /application/mysql/bin/mysql_install_db --basedir=/application/mysql --datadir=/application/mysql/data/  --user=mysql

 

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

[root@localhost support-files]#  chkconfig --add mysqld

[root@localhost support-files]# chkconfig mysqld on

[root@localhost support-files]# chmod +x /etc/init.d/mysqld

[root@localhost support-files]# /etc/init.d/mysqld start

[root@localhost support-files]#

到此就安装完成了。

接下来就是登陆mysql了。一开始是没有密码的，直接就可以登陆。

[root@httpd support-files]# mysql //直接登录(可能出现问题)

必须将mysql 加到系统环境变量才能知道MySQL是哪个。

[root@localhost support-files]# vim /etc/profile

[root@localhost support-files]# grep mysql /etc/profile

PATH="/application/mysql/bin/:$PATH"

[root@localhost support-files]# ./etc/profile //让它生效

[root@localhost support-files]#mysql -uroot -p //就可以登录了

[root@localhost support-files]#

 

刚刚创建root还没有密码，可以为他创建个密码：

/application/mysql/bin/mysqladmin -u root -h moban password 'new-password'

 

第一种方法：（是哪种启动就用哪种关闭）

启动：

/application/mysql/bin/mysqld_safe &

关闭：

mysqladmin shutdown

 

第二种方法：（混合用有问题）

/etc/init.d/mysqld start

/etc/init.d/mysqld stop

注意：安装过程出现这个报错：

[root@moban support-files]# /etc/init.d/mysqld start
Starting MySQL. ERROR! Manager of pid-file quit without updating file.
[root@moban support-files]#  /application/mysql/bin/mysqld_safe &
[1] 46355
[root@moban support-files]# 180526 00:19:21 mysqld_safe Logging to '/var/log/mysqld.log'.

180526 00:19:21 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

解决方法：再次执行

[root@localhost support-files]# /application/mysql/bin/mysql_install_db

 

[root@moban bin]# ps -ef|grep mysql
