安装apache——centos7

下载httpd-2.2.6.tar.bz2  把httpd-2.2.6.tar.bz2放到/soft 下
[root@localhost ~]#cd /soft
[root@localhost soft]#tar jxvf httpd-2.2.6.tar.bz2    //解压apache的压缩包
[root@localhost soft]#cd httpd-2.2.6     //定位到httpd-2.2.6 文件夹下
[root@localhost httpd-2.2.6]#ls     //查看显示httpd-2.2.6 文件夹下内容
[root@localhost httpd-2.2.6]#./configure --help | more    //查看安装apache配置参数
[root@localhost httpd-2.2.6]#./configure  --prefix=/usr/local/apache  --enable-so    //  配置apache路径
[root@localhost httpd-2.2.6]#make     //编译apache
[root@localhost httpd-2.2.6]#make install    //安装apache
[root@localhost httpd-2.2.6]#cd /usr/local/apache   //进入apache的目录     
[root@localhost apache]#  cd conf/
[root@localhost conf]#cp -a httpd.conf httpd.conf-     //备份apache配置文件
[root@localhost conf]#chkconfig  --list httpd     //查看httpd服务是否已存在
[root@localhost conf]#chkconfig httpd off    //关闭系统自带了httpd的服务，如果存在httpd服务   
[root@localhost conf]#service httpd status    //查看自带httpd服务状态
[root@localhost conf]#/usr/local/apache/bin/apachectl -k start    //linux启动apache命令              
[root@localhost conf]#netstat -an | grep :80    //查看linux80端口是否开启
[root@localhost conf]#ps -aux | grep httpd     //linux下查看apache进程
[root@localhost conf]#cd ../..
[root@localhost local]#cp /usr/local/apache/bin/apachectl /etc/rc.d/init.d/apache //拷贝apache启动脚本
[root@localhost local]#vi /etc/rc.d/init.d/apache    // 这里是编辑apache启动脚本
  在开头的#！/bin/sh  下面加上
              #chkconfig: 2345  85  15
[root@localhost local]#chkconfig --add apache    //添加apache服务
[root@localhost local]#chkconfig --list apache    //列出apache服务
[root@localhost local]#service apache stop    //停止apache服务
[root@localhost local]#netstat -an | grep :80     //查看linux的80端口是否关闭
[root@localhost local]#ps -aux | grep httpd     //查看是否存在httpd服务，若果之前自带httpd服务启动的话会导致新添加的apache服务启动失败
[root@localhost local]#service apache start    //启动apache服务
打开你的服务器ip地址，看看是否出现了tomcat的默认首页，如果出现的话，那么恭喜你
linux下安装apache已经成功了
