Mass deployment of enterprise-level automated LNMP

A, LNMP Profile

  1) LNMP is the Internet mainstream WEB server architecture, mainly by Linux + Nginx + MYSQL | Mariadb + PHP combination, you can publish enterprise portals Code (PHP dynamic pages), operation and maintenance personnel need to be able to build an independent LNMP platform.
  2) Based on the manual way of building LNMP WEB MAKE-source platform, steps, instructions are very cumbersome, if companies require fast and efficient configuration platform, by manual operation will consume a lot of labor costs, automation can be introduced SHELL program implementation.

• Nginx Nginx official website to download & unzip the package & compile & install;
• MYSQL MYSQL official website to download software packages & unzip & compile & install;
• PHP official website to download PHP packages & unzip & compile & install;
• LNMP profiles are integrated to create a test page PHPinfo & Access

Two, shell code implementation

Preparing the environment:

• Linux systems: Centos7
• NIC: can Unicom Internet (ie ping through www.baidu.com)
• Recommendation: Turn off the firewall and Selinux before running to prevent the Web site port closed by a firewall
