下面是linux下安裝apache的完整代碼，系統(tǒng)是redhat5.5

下載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    //解壓apache的壓縮包
[root@localhost soft]#cd httpd-2.2.6     //定位到httpd-2.2.6 文件夾下
[root@localhost httpd-2.2.6]#ls     //查看顯示httpd-2.2.6 文件夾下內(nèi)容
[root@localhost httpd-2.2.6]#./configure --help | more    //查看安裝apache配置參數(shù)
[root@localhost httpd-2.2.6]#./configure  --prefix=/usr/local/apache  --enable-so    //  配置apache路徑
[root@localhost httpd-2.2.6]#make     //編譯apache
[root@localhost httpd-2.2.6]#make install    //安裝apache
[root@localhost httpd-2.2.6]#cd /usr/local/apache   //進(jìn)入apache的目錄    
[root@localhost apache]#  cd conf/
[root@localhost conf]#cp -a httpd.conf httpd.conf-     //備份apache配置文件
[root@localhost conf]#chkconfig  --list httpd     //查看httpd服務(wù)是否已存在
[root@localhost conf]#chkconfig httpd off    //關(guān)閉系統(tǒng)自帶了httpd的服務(wù)，如果存在httpd服務(wù)  
[root@localhost conf]#service httpd status    //查看自帶httpd服務(wù)狀態(tài)
[root@localhost conf]#/usr/local/apache/bin/apachectl -k start    //linux啟動(dòng)apache命令              
[root@localhost conf]#netstat -an | grep :80    //查看linux80端口是否開啟
[root@localhost conf]#ps -aux | grep httpd     //linux下查看apache進(jìn)程
[root@localhost conf]#cd ../..
[root@localhost local]#cp /usr/local/apache/bin/apachectl /etc/rc.d/init.d/apache //拷貝apache啟動(dòng)腳本
[root@localhost local]#vi /etc/rc.d/init.d/apache    // 這里是編輯apache啟動(dòng)腳本

  在開頭的#！/bin/sh  下面加上

#chkconfig: 2345  85  15
[root@localhost local]#chkconfig --add apache    //添加apache服務(wù)
[root@localhost local]#chkconfig --list apache    //列出apache服務(wù)
[root@localhost local]#service apache stop    //停止apache服務(wù)
[root@localhost local]#netstat -an | grep :80     //查看linux的80端口是否關(guān)閉
[root@localhost local]#ps -aux | grep httpd     //查看是否存在httpd服務(wù)，若果之前自帶httpd服務(wù)啟動(dòng)的話會(huì)導(dǎo)致新添加的apache服務(wù)啟動(dòng)失敗
[root@localhost local]#service apache start    //啟動(dòng)apache服務(wù)

打開你的服務(wù)器ip地址，看看是否出現(xiàn)了tomcat的默認(rèn)首頁(yè)，如果出現(xiàn)的話，那么恭喜你

linux下安裝apache已經(jīng)成功了
