系统环境：


Linux: CentOS 7.3

http：http/2.4

MySQL：MariaDB 5.5

PHP：5.5.38

    

    引用博客：http://www.cnblogs.com/xqzt/p/5124894.html


1、安装配置源：


        http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm


   安装zabbix源和epel源：


   [root@zabbix ~]# https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

   [root@zabbix ~]# wget http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm

   [root@zabbix ~]# rpm -ivh epel-release-latest-7.noarch.rpm

   [root@zabbix ~]# rpm -ivh zabbix-release-3.2-1.el7.noarch.rpm


    

2、安装Zabbix server and agent（agent是可选的）


        [root@zabbix ~]# yum install zabbix-server zabbix-web zabbix-web-mysql zabbix-agent zabbix-get


        [root@zabbix ~]# yum install zabbix-java-gateway   



3、 zabbix WEB环境搭建（LNMP环境搭建）


        http://www.unixmen.com/install-lamp-server-apache-mariadb-php-centosrhelscientific-linux-7/

        

        Install Apache：


        #yum install httpd   #已自动安装


        [root@zabbix ~]# systemctl start httpd

        [root@zabbix ~]# systemctl status httpd

        [root@zabbix ~]# netstat -anptul|grep httpd

tcp6       0      0 :::80                   :::*                    LISTEN      2952/httpd

[root@zabbix ~]# systemctl enable httpd


        Install MariaDB：

        

        [root@zabbix ~]# yum install mariadb-server mariadb -y

        [root@zabbix ~]# systemctl start mariadb

        [root@zabbix ~]# systemctl status mariadb

        [root@zabbix ~]# netstat -anptul|grep 3306

tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      2800/mysqld 

[root@zabbix ~]# systemctl enable mariadb   

        

        Set MySQL root password


By default, MySQL root password is empty. So, to prevent unauthorized access to MySQL, let us set root user password. Enter the following command to setup mysql root user password:


        [root@zabbix ~]# mysql_secure_installation


NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB

     SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!


In order to log into MariaDB to secure it, we'll need the current

password for the root user.  If you've just installed MariaDB, and

you haven't set the root password yet, the password will be blank,

so you should just press enter here.


Enter current password for root (enter for none): 

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Enter current password for root (enter for none): 

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Enter current password for root (enter for none): 

OK, successfully used password, moving on...


Setting the root password ensures that nobody can log into the MariaDB

root user without the proper authorisation.


Set root password? [Y/n] y

New password: 

Re-enter new password: 

Sorry, passwords do not match.


New password: 

Re-enter new password: 

Password updated successfully!

Reloading privilege tables..

... Success!



By default, a MariaDB installation has an anonymous user, allowing anyone

to log into MariaDB without having to have a user account created for

them.  This is intended only for testing, and to make the installation

go a bit smoother.  You should remove them before moving into a

production environment.


Remove anonymous users? [Y/n] y

... Success!


Normally, root should only be allowed to connect from 'localhost'.  This

ensures that someone cannot guess at the root password from the network.


Disallow root login remotely? [Y/n] y

... Success!


By default, MariaDB comes with a database named 'test' that anyone can

access.  This is also intended only for testing, and should be removed

before moving into a production environment.


Remove test database and access to it? [Y/n] y

- Dropping test database...

... Success!

- Removing privileges on test database...

... Success!


Reloading the privilege tables will ensure that all changes made so far

will take effect immediately.


Reload privilege tables now? [Y/n] y

... Success!


Cleaning up...


All done!  If you've completed all of the above steps, your MariaDB

installation should now be secure.


Thanks for using MariaDB!



        zabx@pass123$


        Install PHP：


        #yum install php php-mysql php-gd php-pear -y  #已经自动安装


        Test PHP：


        Add the following lines：


        [root@zabbix ~]# vim /var/www/html/testphp.php

        [root@zabbix ~]# cat /var/www/html/testphp.php 

        <?php

phpinfo();

?>


     

        测试：http://172.16.*.*/testphp.php

        

        编辑 file /etc/httpd/conf.d/zabbix:


        [root@zabbix ~]# vim /etc/httpd/conf.d/zabbix.conf


        设置时区：

        php_value date.timezone Asia/Shanghai

 


4、设置数据库


       创建MySQL 数据库和用户：


       [root@zabbix ~]# mysql -uroot -p

       

       创建一个数据库‘zabbix’和数据库用户‘zabuser’


       MariaDB [(none)]> create database zabbix character set utf8;

  Query OK, 1 row affected (0.00 sec)


  MariaDB [(none)]> grant all privileges on zabbix.* to 'zabuser'@'localhost' identified by 'zabpass';

       Query OK, 0 rows affected (0.00 sec)


       MariaDB [(none)]> flush privileges;

  Query OK, 0 rows affected (0.00 sec)


  数据库导入zabbix template:


  [root@zabbix zabbix-server-mysql-3.2.7]# pwd

/usr/share/doc/zabbix-server-mysql-3.2.7


  [root@zabbix zabbix-server-mysql-3.2.7]# zcat create.sql.gz |mysql -uzabuser -pzabpass zabbix


5、配置Zabbix server


  编辑文件/etc/zabbix/zabbix_server.conf：


  [root@zabbix ~]# vim /etc/zabbix/zabbix_server.conf


  配置下面的三个参数：


       DBHost=localhost


       DBName=zabbix


       DBUser=zabuser


       DBPassword=zabpass

       

       [root@zabbix ~]# egrep -v "(^#|^$)" /etc/zabbix/zabbix_server.conf 

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

LogFileSize=0

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

DBHost=localhost

DBName=zabbix

DBUser=zabuser

DBPassword=zabpass

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

CacheSize=128M

Timeout=4

AlertScriptsPath=/usr/lib/zabbix/alertscripts

ExternalScripts=/usr/lib/zabbix/externalscripts

LogSlowQueries=3000


6、修改PHP 设置


  修改php.ini为zabbix 建议的设置：


  编辑文件 php.ini：


  [root@zabbix ~]# vim /etc/php.ini


  设置下面的参数：


  max_execution_time = 600

  max_input_time = 600

  memory_limit = 256M

  post_max_size = 32M

  upload_max_filesize = 16M

  date.timezone = Asia/Shanghai


7、修改Firewall 和SELinux 设置


   开放zabbix端口10050 and 10051.


   firewall-cmd --permanent --add-port=10050/tcp


   firewall-cmd --permanent --add-port=10051/tcp


   重启firewall


   systemctl restart firewalld


           如果使用 SELinux, 运行以下命令使 Apache 可以和 Zabbix通信


           setsebool -P httpd_can_connect_zabbix=1


8、允许Zabbix web console 对特定IP段可用 (可选)


       编辑文件 /etc/httpd/conf.d/zabbix.conf,


        vi /etc/httpd/conf.d/zabbix.conf


添加允许访问 zabbix web interface的ip段. 如果设置 ‘Allow from All’, 这可         以允许全部可以访问

复制代码


#

# Zabbix monitoring system php web frontend

#


Alias /zabbix /usr/share/zabbix


<Directory "/usr/share/zabbix">

   Options FollowSymLinks

   AllowOverride None

   Require all granted


   <IfModule mod_php5.c>

       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 date.timezone Asia/Shanghai

   </IfModule>

</Directory>


<Directory "/usr/share/zabbix/conf">

   Require all denied

</Directory>


<Directory "/usr/share/zabbix/include">

   Require all denied

</Directory>


9、启动zabbix-server 和zabbix-agent。重启httpd,，并设置zabbix-server和zabbix-agent开机自动启动


       [root@zabbix ~]# systemctl start zabbix-server

       [root@zabbix ~]# systemctl restart httpd

       [root@zabbix ~]# systemctl restart mariadb

       [root@zabbix ~]# systemctl enable zabbix-server


10、通过控制台配置Zabbix


       http://172.16.*.*/zabbix/setup.php  

       

11、设置zabbix_agent


        [root@zabbix ~]# vim /etc/zabbix/zabbix_agentd.conf


        配置zabbix server 的ip


        Server=127.0.0.1,172.16.*.*

        

        ServerActive=127.0.0.1,172.16.*.*


        [root@zabbix ~]# egrep -v "(^#|^$)" /etc/zabbix/zabbix_agentd.conf 

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

LogFile=/var/log/zabbix/zabbix_agentd.log

LogFileSize=0

Server=127.0.0.1,172.16.*.*

ServerActive=127.0.0.1,172.16.*.*

Hostname=Zabbix server

Include=/etc/zabbix/zabbix_agentd.d/*.conf


        [root@zabbix ~]# systemctl start zabbix-agent 

[root@zabbix ~]# systemctl status zabbix-agent 


[root@zabbix ~]# systemctl enable zabbix-agent



12、添加客户机


        [root@jumpserver ~]# wget http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm

        [root@jumpserver ~]# rpm -ivh zabbix-release-3.2-1.el7.noarch.rpm

        [root@jumpserver ~]# yum install zabbix-agent

        [root@jumpserver ~]# vim /etc/zabbix/zabbix_agentd.conf 


        Server=172.16.*.*

        ServerActive=172.16.*.*


        [root@jumpserver ~]# systemctl start zabbix-agent 

        [root@jumpserver ~]# systemctl status zabbix-agent


        [root@jumpserver ~]# systemctl enable zabbix-agent


      测试：


       [root@zabbix ~]# zabbix_get -s 172.16.*.* -k system.uname

       Linux jumpserver 3.10.0-514.21.1.el7.x86_64 #1 SMP Thu May 25 17:04:51 UTC 2017 x86_64

        

        改变端口号：

        

        [root@zabbix ~]# zabbix_get -s 172.16.*.* -p 10060 -k system.uname

Linux db1 3.10.0-327.el7.x86_64 #1 SMP Thu Nov 19 22:10:57 UTC 2015 x86_64
