编译安装Apache(httpd
httpd有rpm和源码编译的方法，下面介绍一下源码编译安装的方法：操作系统版本：
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.5 (Santiago)
软件版本：httpd-2.4.18.tar.bz2 下载地址：http://apache.fayea.com/httpd/
因为2.4版本的http的依赖apr-util、apr和pcre，所以还需要分别安装
软件版本：apr-1.5.2.tar.gz，apr-util-1.5.4.tar.bz2 下载地址：http://apache.fayea.com/apr/
软件版本：pcre-8.37.tar.bz2下载地址 http://pcre.org/进入下地址ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/
1、安装apr
# tar xvf apr-1.5.2.tar.gz
# cd apr-1.5.2
# ./configure --prefix=/usr/local/apr &&make && make install
2、安装apr-util
# tar xvf apr-util-1.5.4.tar.bz2
# cd apr-util-1.5.4
# ./configure --prefix=/usr/local/apr-util--with-apr=/usr/local/apr && make && make install
3、安装pcre
# tar xvf pcre-8.37.tar.bz2
# cd pcre-8.37
# ./configure --prefix=/usr/local/pcre && make && make install
4、安装httpd
# tar xvfhttpd-2.4.18.tar.bz2
# cd httpd-2.4.18
# ./configure --help #查看编译参数
# ./configure --prefix=/usr/local/apache--enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre=/usr/local/pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-mpms-shared=all--with-mpm=event--enable-proxy --enable-proxy-http --enable-proxy-ajp --enable-proxy-balancer --enable-lbmethod-heartbeat --enable-heartbeat--enable-slotmem-shm--enable-slotmem-plain--enable-watchdog
--enable-modules=MODULE-LIST#--enable-modules=most ，大多数模块都会启用
Space-separated list of modules to enable | "all" |
"most" | "few" | "none" | "reallyall"
--sysconfdir=/etc/httpd#可以将配置文件放在/etc/httpd下面
如果安装有RPM版本的httpd，可以先卸载 ，卸载RPM版本的httpd的方法：
rpm -e httpd-2.2.15 --nodeps
rm /etc/httpd/ -rf
# make install
5、添加PATH环境变量
# cat /etc/profile.d/apache.sh
# export PATH=$PATH:/usr/local/apache/bin
# . /etc/profile.d/apache.sh
6、编辑配置httpd.conf配置文件
# cp /usr/local/apache/conf/httpd.conf/usr/local/apache/conf/httpd.conf.orig
# vim /usr/local/apache/conf/httpd.conf
LoadModule slotmem_shm_module modules/mod_slotmem_shm.so #取消注释，否则启动会报下面的错误
tailf /usr/local/apache/logs/error_log
AH01177: Failed to lookup provider 'shm' for 'slotmem': is mod_slotmem_shm loaded??
[:emerg] AH00020: Configuration Failed, exiting
# apachectl configtest
Syntax OK
# apachectl start
# lsof -i:80
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
httpd 61998 root 4uIPv6 180028 0t0TCP *:http (LISTEN)
httpd 61999 daemon 4uIPv6 180028 0t0TCP *:http (LISTEN)
httpd 62000 daemon 4uIPv6 180028 0t0TCP *:http (LISTEN)
httpd 62001 daemon 4uIPv6 180028 0t0TCP *:http (LISTEN)
# tailf /usr/local/apache/logs/error_log
AH02282: No slotmem from mod_heartmonitor
AH00489: Apache/2.4.18 (Unix) configured -- resuming normal operations
AH00094: Command line: '/usr/local/apache/bin/httpd'
上面的 AH02282: No slotmem from mod_heartmonitor的警告暂时不用管，当加了mod-jk配置文件或者mod_proxy配置文件之后会消失
# apachectl stop
7、编写启动脚本，方便开机自启动
#!/bin/bash
#
# httpd Startup script for the Apache HTTP Server
#
# chkconfig: - 85 15
# description: Apache is a World Wide Web server.It is used to serve \
# HTML files and CGI.
# processname: httpd
# config: /etc/httpd/conf/httpd.conf
# config: /etc/sysconfig/httpd
# pidfile: /var/run/httpd.pid
# Source function library.
. /etc/rc.d/init.d/functions
if [ -f /etc/sysconfig/httpd ]; then
. /etc/sysconfig/httpd
fi
# Start httpd in the C locale by default.
HTTPD_LANG=${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} $httpd
RETVAL=$?

if [ -f ${pidfile} ] ; then

$apachectl $@
RETVAL=$?
;;
*)
echo $"Usage: $prog {start|stop|restart|condrestart|reload|status|fullstatus|graceful|help|configtest}"
exit 1
esac
exit $RETVAL
因为自启动脚本中httpd的pid配置在/var/run/httpd.pid下面，所以还需要修改httpd.conf的配置文件
vim /usr/local/apache/conf/httpd.conf
PidFile "/var/run/httpd.pid"
# apachectl configtest
Syntax OK
# /etc/init.d/httpd start
Starting httpd:
# /etc/init.d/httpd stop
Stopping httpd:
# httpd -D DUMP_MODULES#查看http的支持的模块

Apache模块的目录：
# ls /usr/local/apache/modules/
至此：用两种方式都可以启动
# lsof -i:80 # httpd没有启动
# apachectl start
# lsof -i:80
