zabbix系列（2）部署zabbix5.0之一

上一节搭建了环境，打开虚拟机，xshell连接虚拟机，接下来咱们一起部署zabbix5.0吧。

关闭防火墙
上节已经操作完毕
检查网络环境

[root@localhost ~]# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     udp  --  anywhere             anywhere             udp dpt:domain

ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:bootps

Chain FORWARD (policy ACCEPT)

REJECT     all  --  anywhere             anywhere             reject-with icmp-port-unreachable

Chain OUTPUT (policy ACCEPT)

[root@localhost ~]#

均为accept即可

服务端配置

[root@localhost ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:            972         606          62          10         303         216
Swap:          2047           5        2042

mem：内存
内存尽量大一些，4G为好，显然我们目前虚拟机的内存约1G比较小，需要改大一点。怎么改呢？

这里我采用的是一个图形化界面的修改方式，方便快捷：

右键虚拟机，点击设置：
在这里插入图片描述
直接在页面上修改：

上图可以看到，我已经把内存修改成了2G。

这里要说明一点，开机状态下，虚拟机的内存可以从小往大改，但是不支持从大往小改。若想往小了改，需要关机操作。

修改后，在命令行看结果：

[root@localhost ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:           1996         647        1081          10         267        1304
Swap:          2047           5        2042

获取zabbix官方源

[root@localhost ~]# rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
Retrieving https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
warning: /var/tmp/rpm-tmp.MUCMU1: Header V4 RSA/SHA512 Signature, key ID a14fe591: NOKEY

Updating / installing...
   1:zabbix-release-5.0-1.el7         ################################# [100%]
[root@localhost ~]#

这个时候我们已经有了zabbix源，下图中zabbix.repo这个仓库文件：

[root@localhost ~]# ls /etc/yum.repos.d/
CentOS-Base.repo  CentOS-Debuginfo.repo  CentOS-Media.repo    CentOS-Vault.repo          zabbix.repo
CentOS-CR.repo    CentOS-fasttrack.repo  CentOS-Sources.repo  CentOS-x86_64-kernel.repo

打开仓库文件，可以发现里面的源都是国外的网站http://repo.zabbix.com/，这样下载起来会非常慢：

[root@localhost ~]# vim  /etc/yum.repos.d/zabbix.repo 

[zabbix]

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
"/etc/yum.repos.d/zabbix.repo" 27L, 853C

更换国外源为国内阿里源，加快下载速度

[root@localhost ~]# sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix.repo
[root@localhost ~]# vim  /etc/yum.repos.d/zabbix.repo

更换成功

安装zabbix server 和 agent

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

中间步骤挺多，耐心稍等一小会儿，就成功啦！截个完成的图吧！

Installed:
  zabbix-agent.x86_64 0:5.0.21-1.el7                  zabbix-server-mysql.x86_64 0:5.0.21-1.el7                 

Dependency Installed:
  OpenIPMI.x86_64 0:2.0.27-1.el7  OpenIPMI-libs.x86_64 0:2.0.27-1.el7  OpenIPMI-modalias.x86_64 0:2.0.27-1.el7 
  fping.x86_64 0:3.16-1.el7       unixODBC.x86_64 0:2.3.1-14.el7      

Complete!

太晚了，今天就先到这儿吧，明天继续~~
