第五章 apache启动脚本
5.1 Apache的启动脚本
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。
# cat etc/rc.d/init.d/httpd
#!/bin/bash
#
# httpd Startup script for the Apache HTTP Server
#
# chkconfig: - 85 15
# description: Apache is a World Wide Web server.It is used to serve \
# HTML files and CGI.
# processname: httpd
# config: /etc/httpd/conf/httpd.conf
# config: /etc/sysconfig/httpd
# pidfile: /var/run/httpd.pid
# Source function library.
. /etc/rc.d/init.d/functions
if [ -f /etc/sysconfig/httpd ]; then
. /etc/sysconfig/httpd
fi
# Start httpd in the C locale by default.
HTTPD_LANG=${HTTPD_LANG-"C"}
# This will prevent initlog from swallowing up a pass-phrase prompt if
# mod_ssl needs a pass-phrase from the user.
INITLOG_ARGS=""
# Set HTTPD=/usr/sbin/httpd.worker in /etc/sysconfig/httpd to use a server
# with the thread-based "worker" MPM; BE WARNED that some modules may not
# work correctly with a thread-based MPM; notably PHP will refuse to start.
# Path to the apachectl script, server binary, and short-form for messages.
apachectl=/usr/sbin/apachectl
httpd=${HTTPD-/usr/sbin/httpd}
prog=httpd
pidfile=${PIDFILE-/var/run/httpd.pid}
lockfile=${LOCKFILE-/var/lock/subsys/httpd}
RETVAL=0
STOP_TIMEOUT=${STOP_TIMEOUT-10}
# check for 1.3 configuration
check13 () {
CONFFILE=/etc/httpd/conf/httpd.conf
GONE="(ServerType|BindAddress|Port|AddModule|ClearModuleList|"
GONE="${GONE}AgentLog|RefererLog|RefererIgnore|FancyIndexing|"
GONE="${GONE}AccessConfig|ResourceConfig)"
if LANG=C grep -Eiq "^[[:space:]]*($GONE)" $CONFFILE; then
echo
echo 1>&2 " Apache 1.3 configuration directives found"
echo 1>&2 " please read /usr/share/doc/httpd-2.2.3/migration.html"
failure "Apache 1.3 config directives test"
echo
exit 1
fi
}
# The semantics of these two functions differ from the way apachectl does
# things -- attempting to start while running is a failure, and shutdown
# when not running is also a failure.So we just do it the way init scripts
# are expected to behave here.
start() {
echo -n $"Starting $prog: "
check13 || exit 1
LANG=$HTTPD_LANG daemon --pidfile=${pidfile} $httpd $OPTIONS
RETVAL=$?
echo
[ $RETVAL = 0 ] && touch ${lockfile}
return $RETVAL
}
# When stopping httpd a delay (of default 10 second) is required
# before SIGKILLing the httpd parent; this gives enough time for the
# httpd parent to SIGKILL any errant children.
stop() {
echo -n $"Stopping $prog: "
killproc -p ${pidfile} -d ${STOP_TIMEOUT} $httpd
RETVAL=$?
echo
[ $RETVAL = 0 ] && rm -f ${lockfile} ${pidfile}
}
reload() {
echo -n $"Reloading $prog: "
if ! LANG=$HTTPD_LANG $httpd $OPTIONS -t >&/dev/null; then
RETVAL=$?
echo $"not reloading due to configuration syntax error"
failure $"not reloading $httpd due to configuration syntax error"
else
killproc -p ${pidfile} $httpd -HUP
RETVAL=$?
fi
echo
}
# See how we were called.
case "$1" in

echo $"Usage: $prog {start|stop|restart|condrestart|reload|status|fullstatus|graceful|help|configtest}"
exit 1
esac
exit $RETVAL
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
5.2用lograte分割apache日志
# cat etc/logrotate.d/httpd
/var/log/httpd/*log {
missingok
notifempty
sharedscripts
postrotate
/sbin/service httpd reload > /dev/null 2>/dev/null || true
endscript
}
