由于公司要求需要最新版的ZABBIX2.4.4需要最新版的系统CENTOS7和新版的LNMP环境，所以本人摸索着使用新版的环境搭建了LNMP系统，环境版本如下：
- 系统：CentOS 7 x86_64
- NGINX：nginx-1.7.12
- 数据库：mariadb-10.0.13
- PHP：php-5.5.23
首先做一些准备工作，先把centos7的防火墙更换成iptables，可以参见如下链接
centos7防火墙设置iptables
修改成iptables之后就可以清空iptables里面的过滤规则了，然后再关闭selinux服务。记得不要忘了先安装gcc gcc-c++ wget net-tools等功能哦。
首先安装mariadb
应为数据库编译需要很长时间，所以我这里下载的是已经编译好了的二进制包，下载版本为 mariadb-10.0.13-linux-glibc_214-x86_64.tar.gz
1、下载二进制包到/usr/local/src 目录下：
[root@centos74 src]# wget http://ftp.osuosl.org/pub/mariadb/mariadb-10.0.13/bintar-quantal-amd64/mariadb-10.0.13-linux-glibc_214-x86_64.tar.gz[/code]
2、将压缩包解压到/usr/local 目录下：
[code][root@centos74 src]# tar zvxf mariadb-10.0.13-linux-glibc_214-x86_64.tar.gz -C /usr/local/
3、创建mariadb 数据初始化目录/data/mysql:
4、添加系统用户mysql,禁止登陆系统，同时，将mariadb 数据初始化目录所属主和组都修改为mysql:
5、重命名解压出来的mariadb 目录：
6、进入重命名后的目录，初始化mariadb:

报错：WARNING: The host ‘test4’ could not be looked up with resolveip.
解决办法：vim /etc/hosts 在最后一行添加192.168.1.242 test4
报错：./bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
解决办法：yum -y install libaio-devel libaio
7、复制配置文件到/etc目录覆盖之前的my.cnf:
cp：是否覆盖”/etc/my.cnf”？ y
8、复制mysql 启动脚
