用rpm包安装的apache启动脚本如下,那么用源码安装的apache,我们可以对此脚本进行稍微的修改即可。
[root@localhost httpd]# cat etc/rc.d/init.d/httpd
#!/bin/bash

# httpd Startup script for the Apache HTTP Server

# HTML files and CGI.

if [ -f /etc/sysconfig/httpd ]; then
. /etc/sysconfig/httpd

# Start httpd in the C locale by default.
HTTPD_LANG=${HTTPD_LANG-"C"}
# This will prevent initlog from swallowing up a pass-phrase prompt if
# mod_ssl needs a pass-phrase from the user.
INITLOG_ARGS=""
# Set HTTPD=/usr/sbin/httpd.worker in /etc/sysconfig/httpd to use a server
# with the thread-based "worker" MPM; BE WARNED that some modules may not
# work correctly with a thread-based MPM; notably PHP will refuse to start.

}
# The semantics of these two functions differ from the way apachectl does
# things -- attempting to start while running is a failure, and shutdown

Rpm包执行安装前的作,在源码安装apache之前,需要以下的操作
#rpm -q --scripts httpd
preinstall scriptlet (using /bin/sh):
# Add the "apache" user
/usr/sbin/useradd -c "Apache" -u 48 \
-s /sbin/nologin -r -d /var/www apache 2> /dev/null || :
postinstall scriptlet (using /bin/sh):
# Register the httpd service
/sbin/chkconfig --add httpd
preuninstall scriptlet (using /bin/sh):
if [ $1 = 0 ]; then
/sbin/service httpd stop > /dev/null 2>&1
/sbin/chkconfig --del httpd
Fi
[root@localhost httpd]# cat etc/logrotate.d/httpd
/var/log/httpd/*log {

/sbin/service httpd reload > /dev/null 2>/dev/null || true
endscript
}
