Apache service, or httpd service, how to boot, how to boot. 2010-04-02 09:59

Operating system environment: Red Hat 5, specific as follows: # uname-a Linux machine1 2.6.18-164.el5xen #1 SMP Tue Aug 15:59:52 EDT 2009 x86_64 x86_64 x86_64 # Cat/etc/redhat-release Red Hat Enterprise Linux Server Release 5.4 (Tikanga) Apache, or httpd, version: #/usr/sbin/httpd-v Server version:apache/2.2.3 Server Built:jul 15 2009 09:02:25 Or #/usr/sbin/apachectl-v Server version:apache/2.2.3 Server Built:jul 15 2009 09:02:25 have been talking about Apache, or httpd; In fact, httpd is a service, Apache is a trademark; Just as pure water is a product, and Wahaha is a brand; But because Apache is so famous, it seems that Apache is talking about httpd service. Therefore, the latter text only says httpd service. /usr/sbin/apachectl is actually a script; /USR/SBIN/HTTPD is the real procedure; The following answers how to start the httpd service. Script Startup: #/usr/sbin/apachectl Start [Root@radius guoq]# Ps-ef|grep Apache Apache 6680 6679 0 09:49? 00:00:00/usr/sbin/httpd-k start Apache 6681 6679 0 09:49? 00:00:00/usr/sbin/httpd-k start Apache 6682 6679 0 09:49? 00:00:00/usr/sbin/httpd-k start Apache 6683 6679 0 09:49? 00:00:00/usr/sbin/httpd-k start Apache 6684 6679 0 09:49? 00:00:00/usr/sbin/httpd-k start Apache 6685 6679 0 09:49? 00:00:00/usr/sbin/httpd-k start Apache 6686 6679 0 09:49? 00:00:00/usr/sbin/httpd-k start Apache 6687 6679 0 09:49? 00:00:00/usr/sbin/httpd-k start Root 6689 5393 0 09:49 pts/1 00:00:00 grep Apache Stop is #/usr/sbin/apachectl stop; you're right. If you read the script/usr/sbin/apachectl, you'll find two little secrets: 1. The script accepts the parameter Start,stop,restart, also has the graceful,graceful-stop; 2. In fact, the script or the parameters passed to the/USR/SBIN/HTTPD; Therefore, we can #/usr/sbin/httpd-k start Start service; #/usr/sbin/httpd-k stop Stop service; The following answers how to boot up. If you look at # Find/-name "httpd" /var/log/httpd /usr/sbin/httpd /usr/lib64/httpd /etc/rc.d/init.d/httpd /etc/logrotate.d/httpd /etc/httpd /etc/sysconfig/httpd /home/guoq/osrc/tcl8.4.19/tests/httpd /opt/soft/httpd-2.2.14/httpd /opt/soft/httpd-2.2.14/.libs/httpd /opt/apache2.2.14/bin/httpd We'll find out that Apache is ready to start the boot script, /etc/rc.d/init.d/httpd You can check if it is in the boot list: # chkconfig--list | grep httpd httpd 0: Off 1: Off 2: Off 3: Off 4: off 5: off 6: Off If you want, you can add it to the boot list: #chkconfig--add httpd Alternatively, remove from the boot list: #chkconfig--del httpd In my system, it is already in the boot list: httpd 0: Off 1: Off 2: Off 3: Off 4: off 5: off 6: Off It's just not allowed to boot automatically. I want it to start automatically at the current level of operation, I'm learning Java, and PHP; # chkconfig--level 5 httpd on # chkconfig--list httpd httpd 0: Off 1: Off 2: Off 3: Off 4: Off 5: Enable 6: Off Wait, how do I know my level of operation. # RunLevel N 5 Complete the full text. I do not know why the above method, in my Ubuntu can not run up, so I went to the internet to find a Find the following method: 1 Add the program script to the/ETC/INIT.D directory sudo cp/home/cnscn/my_servd/etc/init.d/ 2) Add to Startup list sudo update-rc.d my_servd defaults 3) will produce the following connections: Adding system startup For/etc/init.d/my_servd ... /ETC/RC0.D/K20MY_SERVD->. /init.d/my_servd /ETC/RC1.D/K20MY_SERVD->. /init.d/my_servd /ETC/RC6.D/K20MY_SERVD->. /init.d/my_servd /ETC/RC2.D/S20MY_SERVD->. /init.d/my_servd /ETC/RC3.D/S20MY_SERVD->. /init.d/my_servd /ETC/RC4.D/S20MY_SERVD->. /init.d/my_servd /ETC/RC5.D/S20MY_SERVD->. /init.d/my_servd 4 Specifies the startup, shutdown level (20 indicates a level) (note the following.) sudo update-rc.d my_servd start 20 3 4 5. Start at the 3,4,5 level sudo update-rc.d my_servd start 20 0 1 2 6.
