CentOS 7.3 install Zabbix3.X

One, configure CentOS 7

Close selinux #setenforce 0 temporarily close

You need to turn off selinux, be sure to turn off this, turning on selinux will cause a series of problems, even the discovery function of zabbix can't be used normally

sed -i"s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

Confirm whether the modification is successful

grep SELINUX/etc/selinux/config

Then restart the system

reboot

Turn off the firewall

systemctl startfirewalld.service#Start firewall

systemctl stopfirewalld.service#Stop firewall

systemctl disablefirewalld.service#Prohibit firewall from booting up

Install YUM source: cd /etc/yum.repos.d/

wgethttp://mirrors.163.com/.help/CentOS7-Base-163.repo

yum clean all

yum makecache

Two, install LAMP

1、 Install MySQL

Starting from the latest version of the linux system, the default is Mariadb instead of mysql!

It is very simple to use the repos that comes with the system:

yum install -y mariadbmariadb-server

Start mariadb

systemctl start mariadb

The previous service management commands can also be used

service mariadb start

Set up auto start

systemctl enable mariadb

Secure initialization, set root password, etc.

mysql_secure_installation

Test login

mysql -uroot -p123456 //password 123456

2. Install Apache software###

yum -y install httpd

vim/etc/httpd/conf/httpd.conf

ServerName localhost:80

systemctl starthttpd.service

systemctl enablehttpd.service

systemctl statushttpd.service //Check the status

"Enabled" means that the httpd service has been set to start, and "active (running)" means that the httpd service is running.

3. Install PHP

# yum -y install php

Install php-mysql

php-mysql is a module for PHP programs to use MySQL database. To install the module, use the command:

# yum -y install php-mysql

systemctl restart httpd //Restart httpd service

After the installation is complete, PHP will generate the configuration file /etc/httpd/conf.d/php.conf, because the configuration file is in the /etc/httpd/conf.d directory, so it will be read by Apache. PHP will also generate a configuration file /etc/httpd/conf.modules.d/10-php.conf, which will also be read by Apache, and its settings allow Apache to load PHP modules. However, the configuration file of the PHP software itself is actually /etc/php.ini.

Can be tested: In order to test whether Apache can call PHP normally, create a new phpinfo.php document in the /var/www/html directory with the content as follows:

It is the syntax of the PHP program, and phpinfo(); is a library provided by the PHP program, which can display information about your web server.
