Modify the httpd service of apache to the root permission.

Modify the httpd service of apache to the root permission.
1. modify the configuration file

[Root @ localhost ~] # Cd/etc/httpd/conf [root @ localhost conf] # vim httpd. conf modify the configuration file

Change User and group to root:

[root@localhost conf]# service httpd restartStopping httpd:                                           [  OK  ]Starting httpd: Syntax error on line 244 of/etc/httpd/conf/httpd.conf:Error:\tApache has not been designed to serve pageswhile\n\trunning as root.

An error occurred while restarting the service.

The error message indicates that if you want to run the apache service as a root user, you must add "-DBIG_SECURITY_HOLE" to the CFLAGS environment variable and re-compile the source code.

2. Download the source code, modify it, and recompile it. 1. Clean up the environment.

[Root @ localhost software] # rpm-qa | grep aprapr-1.3.9-5.el6_2.x86_64apr-util-1.3.9-3.el6_0.1.x86_64apr-util-ldap-1.3.9-3.el6_0.1.x86_64 [root @ localhost software] # rpm-e aprerror: Failed dependencies: libapr-1.so.0 () (64bit) is needed by (installed) apr-util-1.3.9-3.el6_0.1.x86_64libapr-1.so.0 () (64bit) is needed by (installed) httpd-tools-2.2.15-39.el6.centos.x86_64libapr-1.so.0 () (64bit) is needed by (installed) httpd-2.2.15-39.el6.centos.x86_64 [root @ localhost software] # rpm-e -- nodeps apr [-- nodeps indicates not to do dependency check] [root @ localhost software] # rpm-e -- nodeps apr-util [root @ localhost software] # rpm-qa | grep aprapr-util-ldap-1.3.9-3.el6_0.1.x86_64 [root @ localhost software] #

2. Download the source code for compilation and Installation

[root@localhost software]# wget http://archive.apache.org/dist/apr/apr-1.4.5.tar.gz [root@localhost software]# wget http://archive.apache.org/dist/apr/apr-util-1.3.12.tar.gz  [root@localhost software]# wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.10/pcre-8.10.zip[root@localhost software]# lsapr-1.4.5.tar.gz  apr-util-1.3.12.tar.gz  pcre-8.10.zip[root@localhost apr-1.4.5]# ./configure --prefix=/usr/local/apr[root@localhost apr-1.4.5]# make && make install[root@localhost apr-util-1.3.12]# ./configure --prefix=/usr/local/apr-util -with-apr=/usr/local/apr/bin/apr-1-config[root@localhost apr-util-1.3.12]# make && make install[root@localhost pcre-8.10]# ./configure --prefix=/usr/local/pcre[root@localhost pcre-8.10]# make && make install

Download apache and modify the source code:

<p>[root@localhost software]# wgethttp://mirrors.hust.edu.cn/apache//httpd/httpd-2.4.10.tar.gz</p><p>[root@localhost software]# tar -xvf httpd-2.4.10.tar.gz </p><span style="color: windowtext;">[root@localhost software]# cd httpd-2.4.10</span>

Modify the Code include/http_config.h and add it to the file header.

#ifndefBIG_SECURITY_HOLE#defineBIG_SECURITY_HOLE#endif

Re-compile:

[root@localhost httpd-2.4.10]# ./configure --prefix=/usr/local/httpd --enable-ssl --enable-cgi --enable-mods-shared=allable-ssl --enable-cgi --enable-mods-shared=all  --enable-track-vars --enable-rewrite <strong>--with-apr-util=/usr/local/apr-util/ --with-apr=/usr/local/apr --with-pcre=/usr/local/pcre</strong>[root@localhost httpd-2.4.10]# make && make install

3. modify the configuration file and restart the service.

If the service is started, the corresponding User is the default User in the configuration file: deamon or apache. Now modify the configuration file:

[root@localhost httpd-2.4.10]# vim /usr/local/httpd/conf/httpd.conf

Change User and Group to root.
Restart the service:

[Root @ localhost httpd-2.4.10] #/usr/local/httpd/bin/apachectl startAH00558: httpd: cocould not reliably determine the server's fully qualified domain name, using localhost. localdomain. set the 'servername' directive globally to suppress this message: Modify the ServerName in the configuration file

Modify ServerName in the configuration file to: ServerName localhost: 80. Restart the service:

[root@localhost httpd-2.4.10]# /usr/local/httpd/bin/apachectl start[root@localhost httpd-2.4.10]# ps -ef |grep httpdroot      9919     1  0 16:02 ?        00:00:00 /usr/local/httpd/bin/httpd -k startroot      9920  9919  0 16:02 ?        00:00:00 /usr/local/httpd/bin/httpd -k startroot      9921  9919  0 16:02 ?        00:00:00 /usr/local/httpd/bin/httpd -k startroot      9922  9919  0 16:02 ?        00:00:00 /usr/local/httpd/bin/httpd -k startroot     10005 12944  0 16:03 pts/2    00:00:00 grep httpd[root@localhost httpd-2.4.10]#

If an httpd: unrecognized service error occurs during service httpd restart, copy/usr/local/httpd/bin/apachectl to/etc/init. d/httpd.
So far, the permission is successfully modified. Applaud ^

Supplement (possible errors during pcre installation ):

• ./Libtool: line 990: g ++: command not found

  Make [1]: *** [pcrecpp. lo] Error 1

  Make [1]: Leaving directory '/root/software/pcre-8.10'

  Make: *** [all] Error 2

  Solution: yum install gcc + gcc-c ++
• Make & make install errors:

  Libtool: link: unsupported hardcode properties

  Libtool: link: See the libtool documentation for moreinformation.

  Libtool: link: Fatal configuration error.

  Solution: After yum install gcc + gcc-c ++, recompile./configure and then make.
