CentOS 7.2安装zabbix 3.0 LTS

1、zabbix简介

　　zabbix（音同 zæbix）是一个基于WEB界面的提供分布式系统监视以及网络监视功能的企业级的开源解决方案。

　　zabbix能监视各种网络参数，保证服务器系统的安全运营；并提供灵活的通知机制以让系统管理员快速定位/解决存在的各种问题。

　　zabbix由2部分构成，zabbix server与可选组件zabbix agent。

　　zabbix server可以通过SNMP，zabbix agent，ping，端口监视等方法提供对远程服务器/网络状态的监视，数据收集等功能，它可以运行在Linux，Solaris，HP-UX，AIX，Free BSD，Open BSD，OS X等平台上。

　　更多详细信息请访问zabbix官网：https://www.zabbix.com/

2、zabbix版本选择

　　企业使用建议选择zabbix的LTS版本（Long Time Support），尝鲜的可以选择官方的最新版本。

3、zabbix安装

　　本篇随笔基于CentOS 7.2编写。适用于CentOS 7所有版本及RedHat系列。

　　官方yum源：http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm

　　阿里云yum源：https://mirrors.aliyun.com/zabbix/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm

　　安装官方的yum源 

[root@zabbix-server ~]# rpm -ivh http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
Retrieving http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm

   1:zabbix-release-3.2-1.el7         ################################# [100%]
[root@zabbix-server ~]#

　　查看都安装了什么

[root@zabbix-server ~]# rpm -ql zabbix-release
/etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
/etc/yum.repos.d/zabbix.repo
/usr/share/doc/zabbix-release-3.0
/usr/share/doc/zabbix-release-3.0/GPL
[root@zabbix-server ~]#

　　安装zabbix及其他必须的软件

[root@zabbix-server ~]# yum install -y zabbix-server-mysql zabbix-web-mysql

　　由于CentOS 7比较特殊，MySQL已经没了，只能安装mariadb：

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

　　启动并设置开机自启动数据库

[root@zabbix-server bin]# systemctl enable mariadb.service
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
[root@zabbix-server bin]# systemctl start mariadb.service
[root@zabbix-server bin]#

　　初始化数据库

[root@zabbix-server ~]# find / -type f -name "mysql_secure_installation"
/usr/bin/mysql_secure_installation    #mariadb数据库自带的初始化脚本
[root@zabbix-server ~]#
[root@zabbix-server bin]# 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? [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? [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, 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 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 MariaDB
installation should now be secure.
Thanks for using MariaDB!
[root@zabbix-server bin]#

　　创建zabbix数据库

[root@zabbix-server ~]# mysql -uroot -p
Enter password:

　　导入zabbix库的数据

[root@zabbix-server ~]# ll /usr/share/doc/zabbix-server-mysql-3.2.7/create.sql.gz
-rw-r--r-- 1 root root 1161488 Jul 19 00:09 /usr/share/doc/zabbix-server-mysql-3.2.7/create.sql.gz
[root@zabbix-server ~]# zcat /usr/share/doc/zabbix-server-mysql-3.2.7/create.sql.gz|mysql -uzabbix -p zabbix
Enter password:
[root@zabbix-server ~]# mysql -uzabbix -p123456 -e "use zabbix;show tables;"
