CentOS7以yum方式安装zabbix3.2及配置文件详解-创新互联
一、zabbix简介与环境准备
简介详见 ---> zabbix简介
环境准备： CentOS 7（node7）：zabbix-server，web，mysql，agent
mariadb：5.5.50
zabbix组件：3.2.1
apache：2.4.6
二、安装与配置
1、安装数据库（mariadb），可直接yum安装
[root@node7 ~]# vim /etc/yum.repos.d/MariaDB.repo [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.0/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1 [root@node7 ~]# yum -y install MariaDB-client MariaDB-server MariaDB-devel2、配置数据库
2.1 配置数据库配置文件
[root@node7 ~]# vim /etc/my.cnf innodb_file_per_table = 1 skip_name_resolve = 12.2 创建zabbix库并授权普通用户远程访问
[root@node7 ~]# systemctl start mariadb [root@node7 ~]# mysql -e "grant all on *.* to 'root'@'localhost' identified by 'root';" [root@node7 ~]# mysql -uroot -proot Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 18 Server version: 5.5.50-MariaDB MariaDB Server Copyright (c) 2000, 2016, 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 character set utf8 collate utf8_bin; Query OK, 0 rows affected (0.43 sec) MariaDB [(none)]> grant all on zabbix.* to zabbix@localhost identified by 'zabbix'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> grant all on zabbix.* to zabbix@192.168.1.20 identified by 'zabbix'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> flush privileges; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> \q Bye
3、安装zabbix
3.1 创建zabbix用户与组(普通用户）
[root@node7 ~]# groupadd zabbix [root@node7 ~]# useradd -g zabbix zabbix3.2 使用yum方式安装zabbix
[root@node7 ~]# rpm -ivh [root@node7 ~]# yum clean all [root@node7 ~]# yum makecache [root@node7 ~]# yum install zabbix zabbix-server zabbix-server-mysql zabbix-web zabbix-agent zabbix-sender zabbix-get zabbix-web-mysql3.3 将zabbix数据导入数据库
[root@node7 ~]# zcat /usr/share/doc/zabbix-server-mysql-3.2.1/create.sql | mysql -uzabbix -pzabbix zabbix3.4 查看导入数据，并测试zabbix用户远程登录
[root@node7 ~]# mysql -uzabbix -pzabbix Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 21 Server version: 5.5.50-MariaDB MariaDB Server Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | test | | zabbix | +--------------------+ 3 rows in set (0.00 sec) MariaDB [(none)]> use zabbix Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed MariaDB [zabbix]> show tables; 127 rows in set (0.00 sec) MariaDB [zabbix]> \q Bye3.5 配置zabbix-server

3.7 启动zabbix-server
[root@node7 ~]# systemctl start zabbix-server4、配置php，并启动httpd服务
[root@node7 ~]# vim /etc/httpd/conf.d/zabbix.conf php_value date.timezone Asia/Shanghai [root@node7 ~]# systemctl start httpd.service 此时确认iptanles规则放行或禁用，并关闭selinux5、配置agent端，最少指出其server端地址，server端可配置多个
[root@node7 ~]# vim /etc/zabbix/zabbix_agentd.conf Server=127.0.0.1,192.168.1.206、登录web界面http://192.168.1.20/zabbix，初始用户名密码admin/zabbix，看到如下界面，即配置成功
6.1 配置zabbix-web连接数据库
6.2 成功登录
