安装前准备
一、下载网络yum源:
http://mirrors.163.com/.help/centos.html https://opsx.alibaba.com/mirror 1、首先备份/etc/yum.repos.d/CentOS-Base.repo,备份之前要先安装weget(yum -y install wget)
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup 2、选择下载一下两个中任意一个yum源 网易163 yum源: 下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份) • CentOS7 • CentOS6 • CentOS5 wget http://mirrors.163.com/.help/CentOS7-Base-163.repo #163的yum源,
下载到指定目录下wget http://mirrors.163.com/.help/CentOS7-Base-163.repo -P /etc/yum.repos.d/ 阿里云yum源:https://opsx.alibaba.com/mirror wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 注:关于wget的几个参数介绍: -O 指定保存的文件名后下载文件 -c 断点续传 --limit-rare 限速下载 例: wget --limit-rare=3K /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 3、运行以下命令生成缓存 yum clean all yum makecache
二、防火墙设置
1、可以开启防火墙:
[[email protected] ~]# firewall-cmd --permanent --add-service=http
success
[[email protected] ~]# firewall-cmd --permanent --add-service=https
success
[[email protected] ~]# firewall-cmd --reload
success
[[email protected] ~]# systemctl enable firewalld.service
2、如果感觉麻烦可以考虑关闭防火墙:
[[email protected] ~]# systemctl stop firewalld.service
[[email protected] ~]# systemctl disable firewalld.service
三、关闭SELINUX
1、查看SElinux状态:
[[email protected] ~]#/usr/sbin/sestatus -v #如果SELinux status参数为enabled即为开启状态
SELinux status: enabled
[[email protected] ~]# getenforce
Disabled
2、关闭SELinux:
(1)临时关闭(不用重启机器):
setenforce 0 #设置SELinux 成为permissive模式
#setenforce 1 设置SELinux 成为enforcing模式
(2)永久关闭(需要重启服务器)
修改配置文件:
[[email protected] ~]# vim /etc/selinux/config
将SELINUX=enforcing改为SELINUX=disabled
或者sed关闭:
[[email protected] ~]# sed -i "s/^SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
开始安装zabbix
1、参考官网提供的zabbix帮助手册:https://www.zabbix.com/documentation/3.2/manual
2、搭建zabbix的yum仓库:
由于我们epl的yum仓库里存放的zabbix的版本较低,所以我们先搭建一个zabbix的yum仓库,服务端和客户端上都要做这个步骤。
安装过程中如遇见了如下问题,是与原来yum发生冲突卸载即可(此问题是我重复安装zabbix 不同版本yum源导致,一般不会出现): [[email protected] yum.repos.d]# rpm -ivh http://mirrors.aliyun.com/zabbix/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm 获取http://mirrors.aliyun.com/zabbix/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm 警告:/var/tmp/rpm-tmp.DERtgj: 头V4 RSA/SHA512 Signature, 密钥 ID a14fe591: NOKEY 准备中... ################################# [100%] file /etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX from install of zabbix-release-3.2-1.el7.noarch conflicts with file from package zabbix-release-3.0-1.el7.noarch file /etc/yum.repos.d/zabbix.repo from install of zabbix-release-3.2-1.el7.noarch conflicts with file from package zabbix-release-3.0-1.el7.noarch [[email protected] yum.repos.d]# yum -y remove zabbix-release-3.0-1.el7.noarch
如果没有上述问题直接往下执行:
[[email protected] ~]#rpm -ivh http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
或者用下边的方法
[[email protected] yum.repos.d]# rpm -ivh http://101.110.118.57/repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
[[email protected] ~]# yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-get
