本文详细介绍了在Centos7.4环境下安装Apache的过程，并针对安装过程中可能遇到的问题，如Apache启动失败、端口冲突及ServerName配置错误等提供了具体的解决方案。

Centos7.4之安装apache及安装过程问题

一、安装httpd

安装之前，先查看系统中是否存在已经安装了的httpd.rpm包，如果，没有就是没安装，有的话rpm -e 对应的rpm包名进行删除

	#rpm -qa | grep httpd

使用yum安装(自动安装依赖包),简单方便

	#yum -y install httpd

安装成功后，httpd-v 查看安装的apache版本，查找apache的配置文件位置

	#find / -name "httpd.conf"

将找到的源配置文件备份一份，防止错误后无法恢复

	#cp /etc/httpd/conf/httpd.conf	 /etc/httpd/conf/httpd.conf.bak

启动Apache服务

	#systemctl  start httpd.service

开机自动启动Apache服务

	#systemctl enable httpd.service 开机自启httpd
	#systemctl disable httpd.service 开机不启动httpd

查看httpd的状态

	#systemctl status httpd.service

二、安装过程出现的问题

Apache启动失败，Job for httpd.service failed because the control process exited with error code. See “systemctl status httpd.service” and “journalctl -xe” for details

执行命令,查看报错提示

	#systemctl status httpd.service

[root@cloud1 bin]# systemctl status httpd.service
   httpd.service - The Apache HTTP Server

问题是80端口被占用
解决办法：

	//查看80端口的使用情况
	1.netstat -lnp|grep 80
	
	tcp        0      0 192.168.180.68:61027        0.0.0.0:*                   LISTEN      6289/oproxyd        
	tcp        0      0 :::80                       :::*                        LISTEN      846/httpd           
	tcp        0      0 ::ffff:192.168.180.68:7001 :::*                        LISTEN      32015/java         
	//杀掉占用80端口的进程
	2.kill -9 846
	3.若是前两个方法不行的话，则重启后再启动httpd服务

2.Apache启动失败，httpd：httpd: Could not reliably determine the server’s fully qualified domain name, using localhost.localdomain for ServerName

	1.进入apache的配置文件
		vi /etc/httpd/conf/httpd.conf
	2./ServerName 查找ServerName
		#ServerName www.example.com:80
		将其前面的#去掉
		:wq保存并退出
	3.重启服务
		systemctl restart httpd.service
