zabbix安装步骤

zabbix3.4 安装

为了简单起见，以下的安装将zabbix-server,zabbix-agent和mariadb数据库装在同一台服务器中，并通过使用yum源的方式来进行快速搭建zabbix服务。

测试系统环境：CentOS Linux release 7.3.1611 (Core)

搭建服务之前，大家可以查看一下自己服务器的版本号：

[root@localhost yum.repos.d]# cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)

Yum源安装：

# rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm
服务器端安装

# yum install zabbix-server-mysql zabbix-web-mysql
# yum install mariadb-server -y 安装mariadb数据库
# mysqladmin -uroot password '<password>' 修改数据库的root密码
# mysql -uroot -p<password>
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by '<password>';
mysql> quit
#zcat /usr/share/doc/zabbix-server-mysql-3.4.0/create.sql.gz | mysql -uzabbix -p zabbix 导入zabbix所需要的表

Configure database for Zabbix server
# vi /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=<password>

#systemctl start zabbix-server
注意关闭selinux,否则启动报错。
关闭selinux步骤如下：
vi /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=permissive 将此处的SELINUX=enforcing为permissive
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
修改完配置文件以后使用setenforce命令来即时修改配置
# setenforce 0
查看是否修改成功：
getenforce(或者sestatus),如：
# sestatus
[root@localhost ~]# sestatus
SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: permissive
Mode from config file: permissive
Policy MLS status: enabled
Policy deny_unknown status: allowed
Max kernel policy version: 28

zabbix的PHP的前端配置

php_value max_execution_time 300
php_value memory_limit 128M
php_value post_max_size 16M
php_value upload_max_filesize 2M
php_value max_input_time 300
php_value always_populate_raw_post_data -1
php_value date.timezone Asia/Shanghai 此处为自己修改的时区

#systemctl start httpd
http://<server_ip_or_name>/zabbix 进行前端配置安装，zabbix默认的用户为Admin,密码为zabbix
需要关闭防火墙，否则无法访问页面，关闭防火墙：
#systemctl stop firewalld.service

zabbix代理安装 （代理端用于使用监控主机）
# yum install zabbix-agent
# service zabbix-agent start

注意：在后面的创建Item过程中，选择Key时，要将选择的system.cpu.load[<cpu>,<mode>]的key值修改成system.cpu.load，否则会报Invalid first parameter的错误。
