centos7.4下搭建zabbix3.4监控

2018-05-26 本文已影响200人 dabule

这是zabbixe中文官方文档地址: https://www.zabbix.com/documentation/3.4/zh/manual
可以依据这个文档来进行安装.

前期准备:

为避免实验成功确保关闭firewall和selinux

配置selinux

[root@localhost ~]# setenforce 0
[root@localhost ~]# getenforce 
Permissive

-----------分割线-----------

[root@localhost ~]# vim /etc/selinux/config 


# 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=disabled                   #这里改成disabled
# 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


~                                                                                                        
~                                                                                                        
~           
:wq

关闭firewall

[root@localhost ~]# systemctl stop firewalld.service 
[root@localhost ~]# systemctl disable firewalld.service 
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

1.安装源码库配置部署包

安装源码库配置部署包。这个部署包包含了yum配置文件。可以在线安装也可以下载到系统上本地安装这里直接使用在线安装的方式,安装之前要看好系统的版本是否正确,下载对应版本的zabbix.

检查系统版本号:

[root@localhost ~]# cat /etc/redhat-release 
CentOS Linux release 7.4.1708 (Core)

安装部署包:

[root@localhost ~]# rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm
Retrieving http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm
Preparing...                          ################################# [100%]
    package zabbix-release-3.4-1.el7.centos.noarch is already installed

2.安装mariadb及配置

上一个步骤做完了就可使用yum来安装zabbix但是在此之前先安装并配置一下mariadb服务.为啥不用mysql这里不做表述了,个人喜好吧.

安装mariadb:

[root@localhost ~]# yum -y install mariadb mariadb-server.x86_64 
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * epel: mirrors.aliyun.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.163.com
Package 1:mariadb-5.5.56-2.el7.x86_64 already installed and latest version
Package 1:mariadb-server-5.5.56-2.el7.x86_64 already installed and latest version
Nothing to do

启动mariadb服务并配置:

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

-----------分割线-----------

[root@localhost ~]# mysql -uroot -p123456    #这数据库之前已经初始化并设置root密码了

3.安装zabbix并配置

安装zabbix服务:

[root@localhost ~]# yum -y install zabbix-server-mysql.x86_64 zabbix-web-mysql.noarch 
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * epel: mirrors.aliyun.com

 * updates: mirrors.163.com

Complete!

将zabbix数据导入到mariadb中:

[root@localhost ~]# zcat /usr/share/doc/zabbix-server-mysql-3.4.9/create.sql.gz | mysql -uzabbix -pzabbix zabbix

编辑数据库配置:
在/etc/zabbix/zabbix_server.conf中配置,具体配置如下:

# vim /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix

#保存退出,其他暂时不用修改

编辑Zabbix前端的PHP配置:
Zabbix前端的Apache配置文件位于 /etc/httpd/conf.d/zabbix.conf ,主要修改时区,其他可以不修改.

[root@localhost ~]# vim /etc/httpd/conf.d/zabbix.conf 

#
# Zabbix monitoring system php web frontend
#

Alias /zabbix /usr/share/zabbix

<Directory "/usr/share/zabbix">
    Options FollowSymLinks
    AllowOverride None
    Require all granted

    <IfModule mod_php5.c>
        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  不用做修改,如果修改要修改正确的时区,否则会报错的.

</Directory>

<Directory "/usr/share/zabbix/conf">
    Require all denied
</Directory>
"/etc/httpd/conf.d/zabbix.conf" 37L, 832C  

:wq

启动zabbix和httpd服务:

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