一、环境说明: 复制代码 代码如下: [root@beanvm ~]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 6.2 (Santiago) [root@beanvm ~]# uname -a Linux beanvm 2.6.32-220.el6.i686 #1 SMP Wed Nov 9 08:02:18 EST 2011 i686 i686 i386 GNU/Linux
安装完成的MySQL根目录如下: 复制代码 代码如下: [root@beanvm ~]# ls -l /usr/local/mysql/ total 164 drwxr-xr-x. 2 mysql mysql 4096 Feb 15 14:40 bin -rw-r--r--. 1 mysql mysql 17987 Jan 14 23:38 COPYING drwxr-xr-x. 6 mysql mysql 4096 Feb 18 16:32 data drwxr-xr-x. 2 mysql mysql 4096 Feb 15 14:39 docs drwxr-xr-x. 3 mysql mysql 4096 Feb 15 14:39 include -rw-r--r--. 1 mysql mysql 88109 Jan 14 23:38 INSTALL-BINARY drwxr-xr-x. 3 mysql mysql 4096 Feb 15 14:39 lib drwxr-xr-x. 4 mysql mysql 4096 Feb 15 14:40 man -rw-r--r--. 1 mysql mysql 943 Feb 15 14:56 my.cnf -rw-r--r--. 1 mysql mysql 943 Feb 18 16:26 my-new.cnf drwxr-xr-x. 10 mysql mysql 4096 Feb 15 14:40 mysql-test -rw-r--r--. 1 mysql mysql 2496 Jan 14 23:38 README drwxr-xr-x. 2 mysql mysql 4096 Feb 15 14:40 scripts drwxr-xr-x. 28 mysql mysql 4096 Feb 15 14:40 share drwxr-xr-x. 4 mysql mysql 4096 Feb 15 14:40 sql-bench drwxr-xr-x. 3 mysql mysql 4096 Feb 15 14:40 support-files
1.指定root用户密码(默认是没有密码的) 2.删除匿名用户 3.设置root用户的远程访问(对应的要在防火墙中开启3306端口) 4.是否删除测试数据库 5.重载权限表 这里建议使用这个脚本,执行过程如下: 复制代码 代码如下: [mysql@beanvm ~]$ /usr/local/mysql/bin/mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MySQL to secure it, we"ll need the current password for the root user. If you"ve just installed MySQL, and you haven"t set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MySQL root user without the proper authorisation. You already have a root password set, so you can safely answer "n". Change the root password? [Y/n] Y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] Y ... Success! Normally, root should only be allowed to connect from "localhost". This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] n ... skipping. By default, MySQL comes with a database named "test" that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] n ... skipping. Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] Y ... Success! All done! If you"ve completed all of the above steps, your MySQL installation should now be secure. Thanks for using MySQL! Cleaning up...
当然也可以手动完成这些操作: 复制代码 代码如下: [mysql@beanvm ~]$ mysqladmin -u root password "new-password" [mysql@beanvm ~]$ mysqladmin -u root -h beanvm password "new-password" [mysql@beanvm ~]$ mysql -u root -p Enter password: Welcome to the MySQL monitor.
