Centos7安装部署Zabbix3.4

1.关闭selinux和firewall

1.1检测selinux是否关闭

[root@localhost ~]# getenforce
Disabled #Disabled 为关闭

1.1.1临时关闭
[root@localhost ~]# setenforce 0 #设置SELinux 成为enforcing模式

1.1.2永久关闭

[root@localhost ~]# vi /etc/selinux/config：
将SELINUX=enforcing改为SELINUX=disabled
设置后需要重启才能生效

1.2查看默认防火墙状态

[root@localhost ~]# firewall-cmd --state
not running #关闭后显示not running，开启后显示running

1.2.1停止firewall

[root@localhost ~]# systemctl stop firewalld.service

1.2.2禁止firewall开机启动
[root@localhost ~]# systemctl disable firewalld.service

2.Zabbix3.4程序安装

2.1配置zabbix的yum源

[root@localhost ~]# rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm

2.2安装zabbix程序包，安装mysql、zabbxi-agent

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

2.3启动mariadb并设置开机启动，创建数据库实例，授权

[root@localhost ~]# systemctl start mariadb     #启动mariadb
[root@localhost ~]# systemctl enable mariadb #设置开机启动
[root@localhost ~]# mysql                            #登入数据库
MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;   #创建数据库实例
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@'%' identified by 'zabbix'; #授权所有主机访问数据库实例zabbix，用户名/密码：zabbix/zabbix

Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix'; #授权localhost主机名访问数据库实例zabbix，用户名/密码：zabbix/zabbix

Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@localhost.localdomain identified by 'zabbix'; #授权localhost.localdomain主机访问数据库实例zabbix，用户名/密码：zabbix/zabbix

Query OK, 0 rows affected (0.00 sec)

导入初始模式和数据

[root@localhost ~]# cd /usr/share/doc/zabbix-server-mysql-3.4.4/ #进入create.sql.gz所在目录

[root@localhost zabbix-server-mysql-3.4.4]# zcat create.sql.gz |mysql -uroot zabbix #导入出事模式

2.4启动zabbix-server服务

2.4.1配置zabbix-server的配置文件zabbix_server.conf

[root@localhost zabbix-server-mysql-3.4.4]# vi /etc/zabbix/zabbix_server.conf
DBHost=localhost # 数据主机名
DBName=zabbix # 数据库实例
DBUser=zabbix # 用户名
DBPassword=zabbix # 密码

2.4.2启动zabbix-server服务

[root@localhost zabbix-server-mysql-3.4.4]# systemctl start zabbix-server #启动zabbix-server服务
[root@localhost zabbix-server-mysql-3.4.4]# systemctl enable zabbix-server #设置zabbix-server服务开机自启动

无法启动
# systemctl start zabbix-server
Job for zabbix-server.service failed. See 'systemctl status zabbix-server.service' and 'journalctl -xn' for details.

解决方法：先检查selinux是否关闭，关闭后，并安装trousers软件。再次启动zabbix-server服务便可以启动成功。
# yum install trousers -y
# systemctl start zabbix-server

2.5编辑Apache的配置文件，消注释设置正确的时区

[root@localhost zabbix-server-mysql-3.4.4]# 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 always_populate_raw_post_data -1
php_value date.timezone Asia/Shanghai
启动httpd服务，设置开机启动httpd服务

[root@localhost ~]# systemctl start httpd #启动httpd服务
[root@localhost ~]# systemctl enable httpd #设置开机启动httpd服务

3.启动zabbix-agent并设置开机自启动
[root@localhost ~]# systemctl start zabbix-agent # 启动zabbix-agent服务
[root@localhost ~]# systemctl enable zabbix-agent # 设置zabbix-agent服务开机自启动
