CentOS7编译安装新版LNMP环境
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:

[root@centos74 src]# cd /usr/local/mysql/
[root@centos74 mysql]# ./scripts/mysql_install_db --datadir=/data/mysql --user=mysql

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 启动脚本文件到/etc/init.d 目录下并重命名为mysqld:
同时修改启动脚本的权限为755：
chmod 755 /etc/init.d/mysqld
9、编辑启动脚本，定义datadir 路径：
定义数据存放路径：
datadir=/data/mysql
10、将mariadb自带命令放入$PATH
|

|
[root@localhost ~]# PATH=$PATH:/etc/init.d/#当前有效，重启shell就失效
[root@localhost ~]# echo "export PATH=$PATH:/etc/init.d/" >>/etc/profile
[root@localhost ~]# echo "export PATH=$PATH:/usr/local/mysql/bin/" >>/etc/profile
[root@localhost ~]# source !$
|
11、启动mariadb:
|
1
|
[root@centos74 mysql]# /etc/init.d/mysqld start
|
Starting MySQL. SUCCESS!
第二步，开始安装php
这里要先声明一下，针对Nginx的php安装和针对apache的php安装是有区别的，因为Nginx中的php是以fastcgi的方式结合nginx的，可以理解为nginx代理了php的fastcgi，而apache是把php作为自己的模块来调用的。同样的，php官方下载地址: http://www.php.net/downloads.php
下载php

安装php

[root@localhost php-5.3.27]# make && make install

以上每一个步骤，如果没有完全执行正确，那么下一步是无法进行的，使用 echo $? 看结果是否为 “0” , 如果不是，就是没有执行正确。
修改配置文件
|

|
cp php.ini-production /usr/local/php/etc/php.ini
vim /usr/local/php/etc/php-fpm.conf
|
把如下内容写入该文件:

user = php-fpm
group = php-fpm
listen.owner = nobody
listen.group = nobody
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
|
保存配置文件后，检验配置是否正确的方法为:
/usr/local/php/sbin/php-fpm -t
如果出现诸如 “test is successful” 字样，说明配置没有问题。
启动php-fpm

cp /usr/local/src/php-5.5.23/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod 755 /etc/init.d/php-fpm
service php-fpm start
|
如果想让它开机启动，执行:
chkconfig php-fpm on
检测是否启动:
ps aux |grep php-fpm
看看是不是有很多个进程（大概20多个）。

如果想开机启动，请执行:
|

|
chkconfig nginx on
|
更改nginx配置
首先把原来的配置文件清空:

|
> /usr/local/nginx/conf/nginx.conf
|
“>” 这个符号为重定向的意思，单独用它，可以把一个文本文档快速清空。

保存配置后，先检验一下配置文件是否有错误存在:
|
1
|
/usr/local/nginx/sbin/nginx -t
|
如果显示内容如下，则配置正确，否则需要根据错误提示修改配置文件:
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
启动nginx:
|
1
|
service nginx start
|
如果不能启动，请查看 “/usr/local/nginx/logs/error.log” 文件，检查nginx是否启动:
|
1
|
ps aux |grep nginx
|
看是否有进程。
测试是否解析php文件
创建测试文件:
|
1
|
vim /usr/local/nginx/html/2.php
|
内容如下:
|
1
|
<?php echo phpinfo();?>
|
测试:
|
1
|
[root@localhost nginx]# curl localhost/2.php
|
或者使用浏览器打开http://YourServerIPAddress/2.php
重要：如果解析不了，检查日志发现连接不到php，我的php版本为5.5.23，比较新的版本，需要在php/etc/php-fpm.conf文件中添加
|
1
2
|
listen.owner = nobody
listen.group = nobody
|
这两行，再重启一下服务就能使用php了
原因是/tmp/php-fcgi.sock这个文件没有读权限
至此，最新版的LNMP环境源码编译安装完成了
