一.環境介紹

角色	系統	安裝內容
監控端server（192.168.43.101）	CentOS7.4	LAMP架構、Zabbix-server
被監控端clinet（192.168.43.102）	CentOS7.4	Zabbix-agentd

本實驗搭建zabbix最簡單的server-client架構，採用zabbix源碼編譯方式安裝，LAMP架構採用yum安裝

二.實驗具體操作

在server端部署LAMP架構

環境準備

#永久修改主機名
[root@localhost ~]# hostnamectl set-hostname server
[root@localhost ~]# su
#正則關閉selinux核心防護
[root@server ~]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
[root@server ~]# setenforce 0
#查看是否設置成功
[root@server ~]# getenforce 0
Permissive
#關閉防火牆
[root@server ~]# systemctl stop firewalld.service 
[root@server ~]# systemctl disable firewalld.service 
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@server ~]#

安裝軟件包

安裝apache

[root@server ~]# yum install -y httpd

安裝mariadb

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

安裝php以及擴展依賴包

[root@server ~]# yum install -y php php-bcmath php-mbstring \
> php-mysql php-gd php-ldap php-xml

安裝依賴庫

[root@server ~]# yum install -y unixODBC-devel mysql-devel \
> net-snmp-devel libxml2-devel libcurl-devel libevent-devel gcc

修改apache與php的配置文件

#配置apache
[root@server ~]# vi /etc/httpd/conf/httpd.conf 

ServerName 127.0.0.1

DocumentRoot "/var/www/html/zabbix"

[root@server ~]# mkdir -p /var/www/html/zabbix
[root@server ~]# 


#配置php
vim /etc/php.ini
date.timezone = Asia/Shanghai        //設置時區
post_max_size = 32M                //設置上傳文件大小
max_execution_time = 300
max_input_time = 300
always_populate_raw_post_data = -1

配置php界面

[root@server ~]# cat /var/www/html/zabbix/index.php
<?php
phpinfo();
?>
[root@server ~]#

啓動服務並且驗證php界面

[root@server ~]# systemctl start httpd.service 
[root@server ~]# systemctl enable httpd.service 
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
[root@server ~]# systemctl start mariadb.service 
[root@server ~]# systemctl enable mariadb.service 
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
[root@server ~]#

初始化mariadb並且設置zabbix數據庫用戶

設置數據庫

#設置安全導向
[root@server ~]# 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):         //此處回車
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            //是否設置mysql的root賬戶的密碼
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] n
 ... skipping.

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] n
 ... skipping.

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] n
 ... skipping.

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] n
 ... skipping.

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
