1. 关闭防火墙及 selinux
# systemctl disable firewalld # systemctl stop firewalld # firewall-cmd --state not running # reboot
# vi /etc/selinux/config
返回目录
2. 安装 Zabbix Server
参考链接：
https://www.zabbix.com/documentation/4.0/manual/installation/install_from_packages/rhel_centos
https://www.zabbix.com/download?zabbix=4.0&os_distribution=centos&os_version=7&db=mysql&ws=apache
1）ADDING ZABBIX REPOSITORY
# rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm
2）FRONTEND INSTALLATION PREREQUISITES
# yum-config-manager --enable rhel-7-server-optional-rpms
如果遇到 yum-config-manager command not found，安装 yum-utils 后，再执行 上一语句
# yum -y install yum-utils
如果1）、2）安装有问题，连接国外的服务器 repo.zabbix.com 经常连接失败，可参照 https://www.cnblogs.com/bruce-he/p/14385216.html
3）SERVER/PROXY/FRONTEND INSTALLATION
To install Zabbix server # yum install zabbix-server-mysql To install Zabbix proxy with MySQL support: # yum install zabbix-proxy-mysql To install Zabbix frontend (available for RHEL 7, deprecated on RHEL 6) with MySQL support: # yum install zabbix-web-mysql
解决 mysql command not found
# ln -s /mnt/software/mysql/bin/mysql /usr/bin # ln -s /mnt/data/mysql3307/mysql.sock /tmp/mysql.sock 备注：将 mysql 的bin 目录和 data的 sock 软连接到系统默认
4）Run the following on your database host.
# mysql -uroot -p <password1> mysql> create database zabbix character set utf8 collate utf8_bin; mysql> create user zabbix@localhost identified by '<password2>'; mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> flush privileges; mysql> quit;
备注： password1为 mysql root用户的密码； password2为设置的 zabbix 用户的密码
5）On Zabbix server host import initial schema and data. You will be prompted to enter your newly created password
# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
6）CONFIGURE DATABASE FOR ZABBIX SERVER/PROXY
# vi /etc/zabbix/zabbix_server.conf DBHost=localhost DBName=zabbix DBUser=zabbix DBPassword=<password>
7）STARTING ZABBIX SERVER PROCESS
# service zabbix-server start # systemctl enable zabbix-server
8）ZABBIX FRONTEND CONFIGURATION
vi /etc/httpd/conf.d/zabbix.conf 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 max_input_vars 10000 php_value always_populate_raw_post_data -1 php_value date.timezone Asia/Shanghai
9）SELINUX CONFIGURATION
# setsebool -P httpd_can_connect_zabbix on If the database is accessible over network (including 'localhost' in case of PostgreSQL), you need to allow Zabbix frontend to connect to the database too: # setsebool -P httpd_can_network_connect_db on
10）启动apache/zabbix-server服务并设置为开机启动
# systemctl start httpd # systemctl enable httpd # netstat -an |grep 80 tcp 0 0 192.168.56.11:80 0.0.0.0:* LISTEN # systemctl start zabbix-server # systemctl enable zabbix-server
返回目录
3. 配置 front
登录 http://zabbixserverip/zabbix，用户名密码为 Admin/zabbix
4. 安装 Zabbix agent 并启动
安装zabbix agent # yum install zabbix-agent 启动 zabbix agent # systemctl restart zabbix-agent # systemctl enable zabbix-agent
返回目录
问题
1. Zabbix server is running, value = No
# tailf /var/log/zabbix/zabbix_server.log connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
解决办法：
# vi /etc/zabbix/zabbix_server.conf DBSocket=/tmp/mysql.sock 备注： 配置 DBSocket # systemctl stop zabbix-server # systemctl start zabbix-server
2. Zabbix front php 配置有问题，需要重新配置时， http://ip/zabbix/setup.php
3. 安装zabbix之后登陆报错：Error connecting to database: No such file or directory
修改php.ini文件
[root@office_zabbix4_007117 etc]#vim /usr/local/php/etc/php.ini
添加一行：mysqli.default_socket = /mnt/data/mysql3307/mysql.sock
