Centos 7 搭建 zabbix 3.4.5

首先本人是一片空白的进行zabbix搭建工作，其实搭建这个之前我搭建过zabbix 2.4，我感觉之前的那个太老了，然后就又推到了重新干了一遍，感觉收获满满。其实最重要的还是要多折腾，折腾多了就自然而然的学会怎么搭建了。当然之前的搭建也是看了前辈们的操作文档，所以还是非常感谢前辈们的贡献，废话不多说，干起来。

一、软件下载：

rpm软件下载地址：http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/

cd /usr/src/zabbix3.4.5/ //软件包下载目录 (没有目录可以在底下建立一个，当然这个目录随意)

[root@Node3 zabbix3.4.5]# ls

zabbix-agent-3.4.5-1.el7.x86_64.rpm

zabbix-proxy-sqlite3-3.4.5-1.el7.x86_64.rpm

zabbix-web-japanese-3.4.5-1.el7.noarch.rpm

zabbix-get-3.4.5-1.el7.x86_64.rpm

zabbix-sender-3.4.5-1.el7.x86_64.rpm

zabbix-web-mysql-3.4.5-1.el7.noarch.rpm

zabbix-java-gateway-3.4.5-1.el7.x86_64.rpm

zabbix-server-mysql-3.4.5-1.el7.x86_64.rpm

zabbix-web-pgsql-3.4.5-1.el7.noarch.rpm

zabbix-proxy-mysql-3.4.5-1.el7.x86_64.rpm

zabbix-server-pgsql-3.4.5-1.el7.x86_64.rpm

zabbix-proxy-pgsql-3.4.5-1.el7.x86_64.rpm

zabbix-web-3.4.5-1.el7.noarch.rpm

其实我就是用一个笨方法一个一个的获取，比如说获取 zabbix-agent-3.4.5-1.el7.x86_64.rpm 我就用这个命令http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-agent-3.4.5-1.el7.x86_64.rpm 下载它，其他的依次类推一个一个的下载

当然也可以在windows上下载好以后传到linux主机上，看自己的喜好来。

二、关闭防火墙:

[root@Node3 ~]# systemctl stop firewalld.service //停掉防火墙

[root@Node3 ~]# systemctl disable firewalld.service //禁止防火墙开机自启动

Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

[root@Node3 ~]# iptables -X

[root@Node3 ~]# iptables -Z

[root@Node3 ~]# iptables -F

[root@Node3 ~]# iptables -vnL

Chain INPUT (policy ACCEPT 228 packets, 15806 bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 252 packets, 19733 bytes) pkts bytes target prot opt in out source destination

三、禁用SElinux

[root@Node3 ~]# vim /etc/selinux/config //在/etc/selinux/config 把SELNUX=enforcing换成SELINUX=disabled

[root@Node3 ~]# setenforce 0

setenforce: SELinux is disabled

[root@Node3 ~]# getenforce Disabled

[root@Node3 ~]# systemctl reboot

注：部署官方文档

rpm包安装3.4手册：https://www.zabbix.com/documentation/3.4/zh/manual/installation/getting_zabbix

从源代码安装zabbix 3.4： https://www.zabbix.com/documentation/3.4/zh/manual/installation/install#installation_from_sources

四、数据库的安装及配置

这里采用的是MariaDB,MariaDB的目的是完全兼容MySQL，包括API和命令行，使之能轻松成为MySQL的代替品

1）安装MariaDB:

[root@Node3 ~]# yum install mariadb-server mariadb –y //yum安装mariadb

[root@Node3 ~]# rpm -qa | grep mariadb

mariadb-5.5.56-2.el7.x86_64 mariadb-server-5.5.56-2.el7.x86_64 mariadb-libs-5.5.56-2.el7.x86_64

2）设置MariaDB并启动：

1、编辑my.cnf文件，增加以下内容:

[root@Node3 ~]# vim /etc/my.cnf //编辑my.cnf文件

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock innodb_file_per_table = on //每个表使用一张单独的表

skip_name_resolve = on　　//跳过名称反解

# Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0

# Settings user and group are ignored when systemd is used.

# If you need to run mysqld under a different user or group,

# customize your systemd unit file for mariadb according to the

# instructions in http://fedoraproject.org/wiki/Systemd

[mysqld_safe] log-error=/var/log/mariadb/mariadb.log

pid-file=/var/run/mariadb/mariadb.pid

# include all files from the config directory

# !includedir /etc/my.cnf.d

2、启动数据库，并设置开机自启动

[root@Node3 ~]# systemctl start mariadb.service //启动数据库

[root@Node3 ~]# systemctl enable mariadb.service //设置开机自启动

Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

[root@Node3 ~]# systemctl status mariadb.service //查看状态

[root@Node3 ~]# ss -tnl | grep 3306 //查看3306端口是否正常

LISTEN 0 50 *:3306 *:*

3）创建数据库：

[root@Node3 ~]# mysql

Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 2 Server version: 5.5.56-MariaDB MariaDB Server Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> CREATE DATABASE zabbix CHARSET 'utf8' COLLATE 'utf8_bin'; //创建数据库，并设置字符集

Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> GRANT ALL ON zabbix.* TO 'zabbix'@Node3 IDENTIFIED BY 'zabbix'; //授权用户对其数据库的权限

Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> FLUSH PRIVILEGES;

Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> exit

Bye

[root@Node3 ~]# mysql -uzabbix -pzabbix -h Node3 //测试数据库是否登录正常

Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 3 Server version: 5.5.56-MariaDB MariaDB Server Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]>

五、Zabbix3.4.5安装及配置：

1、设置zabbix yum源仓库

[root@Node3 ~]# rpm -Uvh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm //连接外网可以安装yum源的rpm包，让其自动生成zabbix仓库

Retrieving http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm Preparing... ################################# [100%]

Updating / installing... 1:zabbix-release-3.4-1.el7.centos ################################# [100%]

[root@Node3 ~]# ls /etc/yum.repos.d/ //查看仓库是否自动生成

cdrom.repo repo zabbix.repo CentOS-Base.repo

2、安装 zabbix3.4.5

[root@Node3 zabbix3.4.5]# yum -y install zabbix-server-mysql-3.4.5-1.el7.x86_64.rpm zabbix-web-mysql-3.4.5-1.el7.noarch.rpm zabbix-get-3.4.5-1.el7.x86_64.rpm //安装zabbix服务端（直接复制粘贴）

等待安装成功，安装成功后导入数据库文件

3、导入zabbix数据库

[root@Node3 zabbix3.4.5]# zcat /usr/share/doc/zabbix-server-mysql-3.4.5/create.sql.gz |mysql -uzabbix-pzabbix -hNode3 zabbix //导入数据库

4、配置数据库用户及密码

[root@Node3 ~]# vim /etc/zabbix/zabbix_server.conf //修改zabbix_server.conf配置文件红色部分

[root@Node3 ~]# vim /etc/zabbix/zabbix_server.conf //查看并修改部分

LogFile=/var/log/zabbix/zabbix_server.log

LogFileSize=0

PidFile=/var/run/zabbix/zabbix_server.pid

SocketDir=/var/run/zabbix

DBHost=127.0.0.1 //修改数据库地址

DBName=zabbix //修改数据库名

DBUser=zbxuser //修改数据库账号

DBPassword=zbxpass //修改数据库密码

SNMPTrapperFile=/var/log/snmptrap/snmptrap.log

Timeout=4 490:AlertScriptsPath=/usr/lib/zabbix/alertscripts //Zabbix运行脚本存放目录

ExternalScripts=/usr/lib/zabbix/externalscripts

LogSlowQueries=3000

(对比下自己的文件，如果相同则不需要更改)

5、编辑Zabbix前端PHP配置,更改时区

[root@Node3 zabbix]# vim +19 /etc/httpd/conf.d/zabbix.conf

//将#去掉，修改为Asia/Shanghai

6、SELinux配置

[root@Node3 zabbix]# setsebool -P

httpd_can_connect_zabbix on setsebool: SELinux is disabled.

[root@Node3 zabbix]# setsebool -P

httpd_can_cetwork_connect_db on setsebool: SELinux is disabled.

7、开启httpd服务，并设置开机自启动

[root@Node3 zabbix]# systemctl start httpd.service
[root@Node3 zabbix]# systemctl enable httpd.service
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
[root@Node3 zabbix]# ss -tnl | grep 80
LISTEN 0 128 :::80 :::*

8、开启zabbix- server服务，并设置为开机自启动

[root@Node3 zabbix]# systemctl start zabbix-server.service

[root@Node3 zabbix]# 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@Node3 zabbix]# ss -tnl | grep 10051

LISTEN 0 128 *:10051 *:* LISTEN 0 128 :::10051 :::*
