尝试第二次将端口改为81
[[email protected] httpd]# service httpd start

Google 一下,发现原来是 SELinux 安全机制的作用。
(很难搞,如果很多牵扯的权限的事情找不到原因,就可以分析是否是它的作用)
解决方法如下:
查看selinux状态:
[[email protected] httpd]# sestatus
SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: enforcing
Mode from config file: enforcing
Policy version: 21
Policy from config file: targeted
或者用
[[email protected] httpd]# getenforce
Enforcing
关闭selinux状态:(使用无启重启系统的方法)
[[email protected] httpd]# setenforce 0 关闭命令
[[email protected] httpd]# getenforce 重新查看selinux状态
Permissive
尝试再次启动apache
[[email protected] httpd]# service httpd start
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[ OK ] 成功!!
永久去掉启动失效方法:
[[email protected] ~]# ls -Z /root/
-rw——- root root system_u:object_r:user_home_t anaconda-ks.cfg
-rw-r–r– root root root:object_r:user_home_t install.log
-rw-r–r– root root root:object_r:user_home_t install.log.syslog
其中的“user_home_t”就是SELinux策略属性,而需要httpd能访问必须要是“httpd_user_content_t”属性。
执行一下命令修改你的目录属性
chcon -R -t httpd_user_content_t /dir/ #将/dir目录下所有文件属性设置成 “httpd_user_content_t”
接下来重启httpd
[[email protected] httpd]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ]
大功告成。
得到一个结论,一般碰到莫名其妙的问题一定要先看错误日志,linux下大部分软件都有自己的日志,这样定位起来问题才会不花冤枉时间。
当然也可以去禁止掉SELinux。
1.立即关闭SELinux。setenforce 0;#重启失效
2.修改配置文件 vim /etc/selinux/config;把SELINUX修改成”enforcing”—>”disable”;
