1、解決依賴關(guān)系
httpd-2.4.4需要較新版本的apr和apr-util,因此需要事先對(duì)其進(jìn)行升級(jí)。升級(jí)方式有兩種,一種是通過源代碼編譯安裝,一種是直接升級(jí)rpm包。
(1) 編譯安裝apr
# tar xf apr-1.4.6.tar.bz2
# cd apr-1.4.6
# ./configure --prefix=/usr/local/apr
# make && make install
(2) 編譯安裝apr-util
# tar xf apr-util-1.5.2.tar.bz2
# cd apr-util-1.5.2
# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
# make && make install
/usr/local/apr-1.5.2
(3) httpd-2.4.4編譯過程也要依賴于pcre-devel軟件包,需要事先安裝。此軟件包系統(tǒng)光盤自帶,因此,找到并安裝即可。
2、編譯安裝httpd-2.4.4
到官網(wǎng)下載后執(zhí)行如下命令進(jìn)行編譯安裝過程:
# tar xf httpd-2.4.4.tar.bz2
# cd httpd-2.4.4
# ./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-apr=/usr/local/apr-1.5.2 --with-apr-util=/usr/local/apr-util --enable-modules=most --enable-mpms-shared=all --with-mpm=event
# make && make install
(1)構(gòu)建
在全部平臺(tái)中,MPM都可以構(gòu)建為靜態(tài)模塊。在構(gòu)建時(shí)選擇一種MPM,鏈接到服務(wù)器中。如果要改變MPM,必須重新構(gòu)建。為了使用指定的MPM,請(qǐng)?jiān)趫?zhí)行configure腳本時(shí),使用參數(shù) --with-mpm=NAME。NAME是指定的MPM名稱。編譯完成后,可以使用 ./httpd -l 來確定選擇的MPM。 此命令會(huì)列出編譯到服務(wù)器程序中的所有模塊,包括 MPM。
(2)構(gòu)建 MPM 為動(dòng)態(tài)?塊
在Unix或類似平臺(tái)中,MPM可以構(gòu)建為動(dòng)態(tài)模塊,與其它動(dòng)態(tài)模塊一樣在運(yùn)行時(shí)加載。 構(gòu)建 MPM 為動(dòng)態(tài)模塊允許通過修改LoadModule指令內(nèi)容來改變MPM,而不用重新構(gòu)建服務(wù)器程序。在執(zhí)行configure腳本時(shí),使用--enable-mpms-shared選項(xiàng)即可啟用此特性。當(dāng)給出的參數(shù)為all時(shí),所有此平臺(tái)支持的MPM模塊都會(huì)被安裝。還可以在參數(shù)中給出模塊列表。默認(rèn)MPM,可以自動(dòng)選擇或者在執(zhí)行configure腳本時(shí)通過--with-mpm選項(xiàng)來指定,然后出現(xiàn)在生成的服務(wù)器配置文件中。編輯LoadModule指令內(nèi)容可以選擇不同的MPM。
3、修改httpd的主配置文件,設(shè)置其Pid文件的路徑
編輯/etc/httpd/httpd.conf,添加如下行即可:
PidFile "/var/run/httpd.pid"
4、提供SysV服務(wù)腳本/etc/rc.d/init.d/httpd,內(nèi)容如下:
#!/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=${HTTPD_LANG-"C"}
# This will prevent initlog from swallowing up a pass-phrase prompt if
# mod_ssl needs a pass-phrase from the user.
INITLOG_ARGS=""
# Set HTTPD=/usr/sbin/httpd.worker in /etc/sysconfig/httpd to use a server
# with the thread-based "worker" MPM; BE WARNED that some modules may not
# work correctly with a thread-based MPM; notably PHP will refuse to start.
# Path to the apachectl script, server binary, and short-form for messages.
apachectl=/usr/local/apache/bin/apachectl
httpd=${HTTPD-/usr/local/apache/bin/httpd}
prog=httpd
pidfile=${PIDFILE-/var/run/httpd.pid}
lockfile=${LOCKFILE-/var/lock/subsys/httpd}
RETVAL=0
start() {
echo -n $"Starting $prog: "
LANG=$HTTPD_LANG daemon --pidfile=${pidfile} $httpd $OPTIONS
RETVAL=$?
echo
[ $RETVAL = 0 ] && touch ${lockfile}
return $RETVAL
}
stop() {
echo -n $"Stopping $prog: "
killproc -p ${pidfile} -d 10 $httpd
RETVAL=$?
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
start)

status -p ${pidfile} $httpd
RETVAL=$?

start

condrestart)
if [ -f ${pidfile} ] ; then

$apachectl $@
RETVAL=$?
;;
*)
echo $"Usage: $prog {start|stop|restart|condrestart|reload|status|fullstatus|graceful|help|configtest}"
exit 1
esac
exit $RETVAL
而后為此腳本賦予執(zhí)行權(quán)限:
# chmod +x /etc/rc.d/init.d/httpd
加入服務(wù)列表:
# chkconfig --add httpd
