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): 输入空格

Setting the root password ensures that nobody can log into the MySQL

root user without the proper authorisation.

Set 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] y

 ... Success!

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] y

 - Dropping test database...

 ... Success!

 - Removing privileges on test database...

 ... Success!

Reloading the privilege tables will ensure that all changes made so far

will take effect immediately.

Reload privilege tables now? [Y/n] y

 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MySQL

installation should now be secure.

Thanks for using MySQL!

4.nagios到安装

下载nagios： 输入邮箱 下载 

进行解压 

[root@localhost Downloads]# tar -xvf nagios-3.2.3.tar.gz -C /usr/src/

cd /usr/src/nagios-3.2.3/ 创建nagios用户

[root@localhost nagios-3.2.3]# mkdir /usr/local/nagios 

[root@localhost nagios-3.2.3]# chown nagios.nagios /usr/local/nagios

[root@localhost nagios-3.2.3]# ./configure --prefix=/usr/local/nagios/

[root@localhost nagios-3.2.3]# make all

[root@localhost nagios-3.2.3]# make install&&make install-init&&make install-commandmode&&make install-config&&make install-webconf

检测是否安装成功：

[root@localhost nagios-3.2.3]# cd /usr/local/nagios

[root@localhost nagios]# ls

bin  etc  libexec  sbin  share  var

有这6个文件就安装成功了。

修改nagios页面文件：

[root@localhost nagios]# more /etc/httpd/conf.d/nagios.conf 

[root@localhost nagios]# cp /etc/httpd/conf.d/nagios.conf /var/www/html/

添加页面访问帐号：

[root@localhost nagios]# touch /usr/local/nagios/etc/htpasswd.users  

[root@localhost nagios]# /usr/bin/htpasswd -c /usr/local/nagios/htpasswd.users root

New password: 

Re-type new password: 

Adding password for user root

[root@localhost nagios]# cat /usr/local/nagios/etc/htpasswd.users

 root:g1tNZtcuWwfCw

修改nagios配置文件

[root@localhost nagios]# vi /usr/local/nagios/etc/nagios.cfg 

找到

#command_check_interval=15s

command_check_interval=-1

改为

command_check_interval=15s

#command_check_interval=-1

[root@localhost nagios]# touch /usr/local/nagios/var/nagios.log

[root@localhost nagios]# chown nagios.nagios /usr/local/nagios/var/nagios.log 

[root@localhost nagios]# chkconfig nagios on

[root@localhost nagios]# service nagios start

Starting nagios: done.

[root@localhost nagios]# service httpd restart

Stopping httpd:                                            [  OK  ]

Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using ::1 for ServerName

                                                           [  OK  ]

安装完毕：在ie 输入127.0.0.1/nagios  就可看到页面了。

目前是看不到主机信息：必须关闭SELinux 才能看到

命令 setenforce 0； 

配置到话另外写一篇文章
