一、lnmp简介

LNMP代表的就是：Linux系统下Nginx+MySQL+PHP这种网站服务器架构。

Linux是一类Unix计算机操作系统的统称，是目前最流行的免费操作系统。代表版本有：debian、centos、ubuntu、fedora、gentoo等。

Nginx是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP代理服务器。

Mysql是一个小型关系型数据库管理系统。

PHP是一种在服务器端执行的嵌入HTML文档的脚本语言。

这四种软件均为免费开源软件，组合到一起，成为一个免费、高效、扩展性强的网站服务系统。

二、Zabbix简介

zabbix（[`zæbiks]）是一个基于WEB界面的提供分布式系统监视以及网络监视功能的企业级的开源解决方案。

zabbix能监视各种网络参数，保证服务器系统的安全运营；并提供灵活的通知机制以让系统管理员快速定位/解决存在的各种问题。

zabbix由2部分构成，zabbix server与可选组件zabbix agent。

zabbix server可以通过SNMP、zabbix agent、ping端口监视等方法提供对远程服务器/网络状态的监视，数据收集等功能，它可以运行在Linux，Solaris，HP-UX，AIX，Free BSD，Open BSD，OS X等平台上。

三、Centos 7安装lnmp、zabbix

1、Yum安装Nginx

1）配置Centos 7 Nginx Yum源仓库

[root@localhost ~]# rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

Retrieving http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

warning: /var/tmp/rpm-tmp.PiXlZn: Header V4 RSA/SHA1 Signature, key ID 7bd9bf62: NOKEY

2、停止Nginx

[root@localhost ~]# systemctl stop nginx

3、重载Nginx

[root@localhost ~]# systemctl reload nginx

4、重启Nginx

[root@localhost ~]# systemctl restart nginx

5、查询Nginx运行状态

[root@localhost ~]# systemctl status nginx

6、查询Nginx进程

[root@localhost ~]# ps -ef |grep nginx

3）解压

[root@localhost ~]# tar xf zabbix-6.2.8.tar.gz

4）预编译

[root@localhost ~]# cd zabbix-6.2.8

# 指定C99编译（gcc默认使用的是C89的标准，而C89的标准不支持在for中定义循环变量，不指定编译报错解决起来你会疯）

[root@localhost zabbix-6.2.8]# export CFLAGS="-std=gnu99"

[root@localhost zabbix-6.2.8]# ./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --with-mysql --enable-ipv6 --with-net-snmp --with-libcurl --with-libxml2 --with-openipmi
