一般会员编译的apache，要在该会员下启动1024端口以下的apache端口。
1、假设一般会员为sims20,用该会员编译 安置了一个apache,安置途径为/opt/aspire/product/sims20/apache
./configure --prefix=/opt/aspire/product/sims20/apache --enable-so --enable-modules=all --enable-mods-shared=all --enable-mods-shared='proxy proxy_ajp proxy_balancer proxy_connect proxy_ftp proxy_http proxy_rewrite' make make install
2、编译完成后，设定http.conf的监听端口为80
3、直接用一般会员sims20启动
[sims20@bcd-app01 bin]$ ./apachectl start (13)Permission denied: make_sock: could not bind to address [::]:80 (13)Permission denied: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs
出错缘由：在linux下，一般会员只能用1024以上的端口，而1024之内的端口只能由root会员才可以使用
4、利用setuid来解决问题，这样使用httpd能以root权限运转
用root会员登录，进入/opt/aspire/product/sims20/apache/bin，离别用chown root httpd、chmod u+s httpd 设定httpd的属主为root及非凡权限
[root@bcd-app01 bin]# ls -l httpd -rwxr-xr-x 1 sims20 aspire 3517470 3月 15 17:12 httpd [root@bcd-app01 bin]# chown root httpd [root@bcd-app01 bin]# ls -l httpd -rwxr-xr-x 1 root aspire 3517470 3月 15 17:12 httpd [root@bcd-app01 bin]# chmod u+s httpd [root@bcd-app01 bin]# ls -l httpd -rwsr-xr-x 1 root aspire 3517470 3月 15 17:12 httpd
5、从新进入一般会员sims20,启动apache
[sims20@bcd-app01 bin]$ ./apachectl start
可以正常启动，没报错
6、试着拜访一下
[sims20@bcd-app01 bin]$ curl http://10.24.12.159:80 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>403 Forbidden</title> </head><body> <h1>Forbidden</h1> <p>You don't have permission to access / on this server.</p> </body></html>
报403 Forbidden错误
7、看一下进程
[sims20@bcd-app01 bin]$ ps -ef |grep httpd root 7841 1 0 17:24 ? 00:00:00 /opt/aspire/product/sims20/apache/bin/httpd -k start daemon 7844 7841 0 17:24 ? 00:00:00 /opt/aspire/product/sims20/apache/bin/httpd -k start daemon 7845 7841 0 17:24 ? 00:00:00 /opt/aspire/product/sims20/apache/bin/httpd -k start daemon 7846 7841 0 17:24 ? 00:00:00 /opt/aspire/product/sims20/apache/bin/httpd -k start daemon 7847 7841 0 17:24 ? 00:00:00 /opt/aspire/product/sims20/apache/bin/httpd -k start daemon 7848 7841 0 17:24 ? 00:00:00 /opt/aspire/product/sims20/apache/bin/httpd -k start sims20 8006 3026 0 17:29 pts/4 00:00:00 grep httpd
如何跑出daemon 会员了， 本来httpd主进程依然以root会员的权限运转，而它的子进程将以一个较低权限的会员运转 ，而这个较低权限会员daemon 在http.conf中配置
8、在http.conf中配置一下，将会员改成root
User daemon Group daemon
改成
User root Group root
9、再次用一般会员启动apache
[sims20@bcd-app01 bin]$ ./apachectl restart Syntax error on line 76 of /opt/aspire/product/sims20/apache/conf/httpd.conf: Error:\tApache has not been designed to serve pages while\n\trunning as root. There are known race conditions that\n\twill allow any local user to read any file on the system.\n\tIf you still desire to serve pages as root then\n\tadd -DBIG_SECURITY_HOLE to the CFLAGS env variable\n\tand then rebuild the server.\n\tIt is strongly suggested that you instead modify the User\n\tdirective in your httpd.conf file to list a non-root\n\tuser.\n
不可的，要从新加参数编译
10、再次修改在http.conf中配置一下，将会员改成一般会员吧
改成
User sims20 Group aspire
11、再次用一般会员sims20启动apache
[sims20@bcd-app01 bin]$ ./apachectl start [sims20@bcd-app01 bin]$ ps -ef |grep httpd root 9720 1 0 18:09 ? 00:00:00 /opt/aspire/product/sims20/apache/bin/httpd -k start sims20 9721 9720 0 18:09 ? 00:00:00 /opt/aspire/product/sims20/apache/bin/httpd -k start sims20 9722 9720 0 18:09 ? 00:00:00 /opt/aspire/product/sims20/apache/bin/httpd -k start sims20 9723 9720 0 18:09 ? 00:00:00 /opt/aspire/product/sims20/apache/bin/httpd -k start sims20 9724 9720 0 18:09 ? 00:00:00 /opt/aspire/product/sims20/apache/bin/httpd -k start sims20 9725 9720 0 18:09 ? 00:00:00 /opt/aspire/product/sims20/apache/bin/httpd -k start sims20 9739 3026 0 18:09 pts/4 00:00:00 grep httpd
12、试着拜访一下
[sims20@bcd-app01 bin]$ curl http://10.248.12.159:80 <html><body><h1>It works!</h1></body></html>
成功了。
