Apache遇到的问题：APR not found

#./configure --prefix……检查编辑环境时出现：

checking for APR... no configure: error: APR not found .  Please read the documentation.

可以用./configure –help | grep apr 查看帮助。 --with-included-apr     Use bundled copies of APR/APR-Util --with-apr=PATH         prefix for installed APR or the full path to apr-config --with-apr-util=PATH    prefix for installed APU or the full path to 安装APR(Apache Portable Runtime ) 下载：http://apr.apache.org/download.cgi

#cd /tmp/52lamp/ //源码存放位置 #tar -zxvf apr-1.4.2.tar.gz //unzip -o apr-1.4.2.zip #cd apr-1.4.2 #./configure #make #make install

再次检查编译环境出现

checking for APR-util... no configure: error: APR-util not found .  Please read the documentation.

#./configure –help | grep apr-util --with-apr-util=PATH    prefix for installed APU or the full path to

下载：http://download.chinaunix.net/download/0001000/472.shtml #tar -zxvf apr-util-1.3.9.tar.gz #cd apr-util-1.3.9 #./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr #make #make install

./configure仍提示APR-util not found，增加--with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util后出现 configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

#./configure –help | grep pcre --with-pcre=PATH        Use external PCRE library

下载：http://sourceforge.net/projects/pcre #unzip -o pcre-8.10.zip #cd pcre-8.10 #./configure --prefix=/usr/local/pcre #make #make install

继续安装Apache/httpd，./configure 时加上参数 --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre，这个问题就解决了

注意：Apache在安装时不会检查参数是否正确，错误的参数会直接被丢弃，不会报告给用户。但可以使用echo $?命令检查是否有错误，当输出结果为0时表示没有错误。

#echo $? 0

#make #make install

复制Apache启动文件 #cp /usr/local/httpd/bin/apachectl /sbin/

启动Apache #apachectl start

设置Apache开机自启动 #vi /etc/rc.d/rc.local 增加一行 /sbin/apachectl start

或者将httpd服务添加到ntsysv服务管理工具 #apachectl stop //关闭Apache以免不必要的麻烦 #cp /usr/local/httpd/bin/apachectl /etc/rc.d/init.d/httpd #vi /etc/rc.d/init.d/httpd 修改为 #!/bin/sh # #chkconfig: 345 85 15 //#不能省略，注意空格 #description: httpd for 52lamp 20101016 21:54 //任意字符串 # ......

第二行中345的含义： #       0 - operation completed successfully #       1 - #       2 - usage error #       3 - httpd could not be started #       4 - httpd could not be stopped #       5 - httpd could not be started during a restart

修改有关权限 #cd /etc/rc.d/init.d/ #chmod a+x httpd #chkconfig --add httpd

#ntsysv httpd已经在列表中，按F1可以看到刚才编写的服务描述httpd for 52lamp 20101016 21:54。

#apachectl start #ps -e |grep httpd 23247 ?        00:00:00 httpd 23248 ?        00:00:00 httpd 23249 ?        00:00:00 httpd 23251 ?        00:00:00 httpd 23252 ?        00:00:00 httpd

在浏览器中输入127.0.0.1，看起来一切正常；但是局域网内其他电脑不能访问！

#service iptables stop

如果不想关闭防火墙，放开80端口即可。

#vi /etc/sysconfig/iptables 增加一行-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT #service iptables restart //重启防火墙

现在一切OK
