安装lnmpa 是出现nginx 502 Bad Gateway错误的一个解决办法
今天在虚拟机上安装了centos 5.6 测试lampa 0.7，一切顺利，最后一步重新启动apache报如下错误:
httpd: Syntax error on line 53 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/modules/libphp5.so into server: /usr/local/apache/modules/libphp5.so: cannot restore segment prot after reloc: Permission denied
解决办法：
原因是Linux有一个SELinux保护模式引起的。
1关闭SELINUX的方法:
vi /etc/selinux/config 将SELINUX=enforcing 改成SELINUX=disabled需要重启
2不关闭SELINUX的方法:
# setenforce 0
# chcon -c -v -R -u system_u -r object_r -t textrel_shlib_t /usr/local/apache/modules/libphp5.so
# service httpd restart
# setenforce 1 设置了
# /root/lnmpa restart

安装教程上面的两种设置了，还是502，也重启过服务器了
该怎么解决呢 找到问题了 我升级到php5.4/usr/local/php/里面就会只有一个文件夹 现在升级到5.3.6就正常了
