集群监控系统

前言

Zabbix 是由 Alexei Vladishev 开发的一种网络监视、管理系统，基于 Server-Client 架构。可用于监视各种网络服务、服务器和网络机器等状态。

使用各种 Database-end 如 MySQL, PostgreSQL, SQLite, Oracle 或 IBM DB2 储存资料。Server 端基于 C语言、Web 管理端 frontend 则是基于 PHP 所制作的。Zabbix 可以使用多种方式监视。可以只使用 Simple Check 不需要安装 Client 端，亦可基于 SMTP 或 HTTP … 各种协定做死活监视。在客户端如 UNIX, Windows 中安装 Zabbix Agent 之后，可监视 CPU Load、网络使用状况、硬盘容量等各种状态。而就算没有安装 Agent 在监视对象中，Zabbix 也可以经由 SNMP、TCP、ICMP、利用 IPMI、SSH、telnet 对目标进行监视。另外，Zabbix 包含 XMPP 等各种 Item 警示功能。Zabbix 的授权是属于 GPLv2。

一、安装http

1、安装软件包

[root@zabbix]# yum -y install httpd

2、删除欢迎词

[root@zabbix]# rm -f /etc/httpd/conf.d/welcome.conf

3、修改配置文件

[root@zabbix]# vi /etc/httpd/conf/httpd.conf
# line 86: change to admin's email address
ServerAdmin root@srv.world
# line 95: change to your server's name
ServerName www.srv.world:80
# line 151: change
AllowOverride All
# line 164: add file name that it can access only with directory's name
DirectoryIndex index.html index.cgi index.php
# 在后面新增
# server's response header
ServerTokens Prod
# keepalive is ON
KeepAlive On

4、启动服务并设置开机启动

[root@zabbix]# systemctl start httpd
[root@zabbix]# systemctl enable httpd

5、设置防火墙

[root@zabbix]# firewall-cmd --add-service=http --permanent
success
[root@zabbix]# firewall-cmd --reload
Success

6、写入测试文件

[root@zabbix]# vi /var/www/html/index.html
<html>
<body>
<div style="width: 100%; font-size: 40px; font-weight: bold; text-align: center;">
Test Page
</div>
</body>
</html>

测试

二、安装PHP

1、安装软件包

[root@zabbix]# yum -y install php php-mbstring php-pear

修改配置文件

[root@zabbix]# vi /etc/php.ini
# line 878: 修改时区
date.timezone = "Asia/Shanghai"

2、重启http服务

[root@zabbix]# systemctl restart httpd

3、创建测试文件

[root@zabbix]# vi /var/www/html/index.php
<html>
<body>
<div style="width: 100%; font-size: 40px; font-weight: bold; text-align: center;">
<?php
print Date("Y/m/d");
?>
</div>
</body>
</html>

4、测试

三、安装数据库

1、安装软件包

[root@zabbix]# yum -y install mariadb-server

2、修改配置文件

[root@zabbix]# vi /etc/my.cnf
# add follows within [mysqld] section
[mysqld]
character-set-server=utf8

3、启动服务并设置开机启动

[root@zabbix]# systemctl start mariadb
[root@zabbix]# systemctl enable mariadb

4、初始化数据库

[root@zabbix]# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, 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 MariaDB
root user without the proper authorisation.

# set root password
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB 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
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
Disallow root login remotely? [Y/n] y
... Success!

By default, MariaDB 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
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
Reload privilege tables now? [Y/n] y
... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

5、连接数据库

[root@zabbix]# mysql -u root -p
Enter password:     # MariaDB root password you set
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 3
Server version: 5.5.37-MariaDB MariaDB Server
