• 九周第五次课（9月29日）

• 11.14/11.15 Apache和PHP结合

• 11.16/11.17 Apache默认虚拟主机

11.14 Apache和PHP结合（上）

• httpd主配置文件/usr/local/apache2.4/conf/httpd.conf

-vim/usr/local/apache2.4/conf/httpd.conf//修改以下4个地方ServerNameRequirealldeniedAddTypeapplication/x-httpd-php.phpDirectoryIndexindex.htmlindex.php-/usr/local/apache2.4/bin/apachectl-t//测试语法-/usr/local/apache2.4/bin/apachectlstart//启动服务-netstat-lntp-curllocalhost-vim/usr/local/apache2.4/htodcs/test.php//增加如下内容<?phpecho123;?>curllocalhost/test.php

• 先打开httpd的配置文件

• 刚才把servername打开了 也就不再提示那个错误了 httpd: Could not reliably determine the server‘s fully qualified domain name, using localhost.localdomain. Set the ‘ServerName‘ directive globally to suppress this message httpd not running, trying to start

• 这是第一处，第二处 Require all denied

• 用网页访问地址192.168.202.131（本机ip）带不开，再用windowsping 下，是可以ping通，试下telnet 访问下80端口 使用telnet 192.168.202.131 80

• 因为windows 并没有打开tenet的客户端，所以它会提示没有这个命令

• 打开telnet客户端方式-打开控制面板-程序-程序和功能-打开或关闭windows功能

• 使用telnet 192.168.202.131 80 结果是 C:\Users\Administrator.USER-20170629EN>telnet 192.168.202.131 80 正在连接192.168.202.131...无法打开到主机的连接。 在端口 80: 连接失败 80端口并不通，因为在linux服务器上并没有打开80端口

• 使用iptables -nvL 看下规则

[root@localhost~]#iptables-nvLChainINPUT(policyACCEPT0packets,0bytes)pktsbytestargetprotoptinoutsourcedestination66054606ACCEPTall--**0.0.0.0/00.0.0.0/0ctstateRELATED,ESTABLISHED180ACCEPTall--lo*0.0.0.0/00.0.0.0/0251798INPUT_directall--**0.0.0.0/00.0.0.0/0251798INPUT_ZONES_SOURCEall--**0.0.0.0/00.0.0.0/0251798INPUT_ZONESall--**0.0.0.0/00.0.0.0/000DROPall--**0.0.0.0/00.0.0.0/0ctstateINVALID231686REJECTall--**0.0.0.0/00.0.0.0/0reject-withicmp-host-prohibitedChainFORWARD(policyACCEPT0packets,0bytes)pktsbytestargetprotoptinoutsourcedestination00ACCEPTall--**0.0.0.0/00.0.0.0/0ctstateRELATED,ESTABLISHED00ACCEPTall--lo*0.0.0.0/00.0.0.0/000FORWARD_directall--**0.0.0.0/00.0.0.0/000FORWARD_IN_ZONES_SOURCEall--**0.0.0.0/00.0.0.0/000FORWARD_IN_ZONESall--**0.0.0.0/00.0.0.0/000FORWARD_OUT_ZONES_SOURCEall--**0.0.0.0/00.0.0.0/000FORWARD_OUT_ZONESall--**0.0.0.0/00.0.0.0/000DROPall--**0.0.0.0/00.0.0.0/0ctstateINVALID00REJECTall--**0.0.0.0/00.0.0.0/0reject-withicmp-host-prohibitedChainOUTPUT(policyACCEPT545packets,76871bytes)pktsbytestargetprotoptinoutsourcedestination54576871OUTPUT_directall--**0.0.0.0/00.0.0.0/0ChainFORWARD_IN_ZONES(1references)pktsbytestargetprotoptinoutsourcedestination00FWDI_publicall--ens33*0.0.0.0/00.0.0.0/0[goto]00FWDI_publicall--+*0.0.0.0/00.0.0.0/0[goto]ChainFORWARD_IN_ZONES_SOURCE(1references)pktsbytestargetprotoptinoutsourcedestinationChainFORWARD_OUT_ZONES(1references)pktsbytestargetprotoptinoutsourcedestination00FWDO_publicall--*ens330.0.0.0/00.0.0.0/0[goto]00FWDO_publicall--*+0.0.0.0/00.0.0.0/0[goto]ChainFORWARD_OUT_ZONES_SOURCE(1references)pktsbytestargetprotoptinoutsourcedestinationChainFORWARD_direct(1references)pktsbytestargetprotoptinoutsourcedestinationChainFWDI_public(2references)pktsbytestargetprotoptinoutsourcedestination00FWDI_public_logall--**0.0.0.0/00.0.0.0/000FWDI_public_denyall--**0.0.0.0/00.0.0.0/000FWDI_public_allowall--**0.0.0.0/00.0.0.0/000ACCEPTicmp--**0.0.0.0/00.0.0.0/0ChainFWDI_public_allow(1references)pktsbytestargetprotoptinoutsourcedestinationChainFWDI_public_deny(1references)pktsbytestargetprotoptinoutsourcedestinationChainFWDI_public_log(1references)pktsbytestargetprotoptinoutsourcedestinationChainFWDO_public(2references)pktsbytestargetprotoptinoutsourcedestination00FWDO_public_logall--**0.0.0.0/00.0.0.0/000FWDO_public_denyall--**0.0.0.0/00.0.0.0/000FWDO_public_allowall--**0.0.0.0/00.0.0.0/0ChainFWDO_public_allow(1references)pktsbytestargetprotoptinoutsourcedestinationChainFWDO_public_deny(1references)pktsbytestargetprotoptinoutsourcedestinationChainFWDO_public_log(1references)pktsbytestargetprotoptinoutsourcedestinationChainINPUT_ZONES(1references)pktsbytestargetprotoptinoutsourcedestination251798IN_publicall--ens33*0.0.0.0/00.0.0.0/0[goto]00IN_publicall--+*0.0.0.0/00.0.0.0/0[goto]ChainINPUT_ZONES_SOURCE(1references)pktsbytestargetprotoptinoutsourcedestinationChainINPUT_direct(1references)pktsbytestargetprotoptinoutsourcedestinationChainIN_public(2references)pktsbytestargetprotoptinoutsourcedestination251798IN_public_logall--**0.0.0.0/00.0.0.0/0251798IN_public_denyall--**0.0.0.0/00.0.0.0/0251798IN_public_allowall--**0.0.0.0/00.0.0.0/0160ACCEPTicmp--**0.0.0.0/00.0.0.0/0ChainIN_public_allow(1references)pktsbytestargetprotoptinoutsourcedestination152ACCEPTtcp--**0.0.0.0/00.0.0.0/0tcpdpt:22ctstateNEWChainIN_public_deny(1references)pktsbytestargetprotoptinoutsourcedestinationChainIN_public_log(1references)pktsbytestargetprotoptinoutsourcedestinationChainOUTPUT_direct(1references)pktsbytestargetprotoptinoutsourcedestination[root@localhost~]#；临时增加一条规则，允许80端口访问[root@localhost~]#iptables-IINPUT-ptcp--dport80-jACCEPT[root@localhost~]#

• 这个时候再来看网页 ，刷新下，显示可以了，能够访问了 It works ！

• 再看下telenet 再试下，telnet 192.168.202.131 80 ，只要显示成这个样子说明80端口通了

• 650) this.width=650;" src="http://oqxf7c508.bkt.clouddn.com/blog/20171006/144747815.png?imageslim" alt="mark" style="border-style:none;background-color:rgb(255,255,255);" />

• 按ctrl + ] 再输quit 就退出来了

• 再把那条规则删掉
