Linux下Apache的安装与配置

一、编译安装
1、解决依赖关系

安装httpd 2.4.4时首先需要解决依赖关系,httpd 2.4.4需要较新版本的apr和apr-util。升级方式有两种,一种是通过源代码编译安装,一种是直接升级rpm包。本文选择第一种方法来进行升级。在这里我们下载 apr-1.4.6.tar.bz2与apr-util-1.5.2.tar.bz2版本。为了以后不必要的麻烦,在这里一定要保证系统时间正确,不正确的(data自行修改)。
apr和apr-util的下载路径为:http://archive.apache.org/dist/apr/ 
(1)首先根据惯例剪切apr与apr-util到/usr/local/src下,然后进行解压操作
mv  apr-1.4.6.tar.bz2  /usr/local/src
mv  apr-util-1.5.2.tar.bz2  /usr/local/src
tar -xjvf apr-1.4.6.tar.bz2
tar -xjvf apr-util-1.5.2.tar.bz2
(2)编译安装apr
cd apr-1.4.6
./configure --prefix=/usr/local/apr      #安装在/usr/local/下 命名为apr
make
make install
(3)编译安装apr-util
cd apr-util-1.5.2
 ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
make
make install
(4) httpd-2.4.4编译过程也要依赖于pcre-devel软件包,需要事先安装。此软件包系统光盘自带,因此,找到并安装即可。
yum -y install pcre-devel
到此为止基本上解决了依赖关系。
2、编译安装httpd-2.4.4
下载httpd-2.4.4.tar.bz2下载地址为https://archive.apache.org/dist/httpd/
(1)首先根据惯例剪切httpd-2.4.4.tar.bz2到/usr/local/src下,然后进行解压操作
mv httpd-2.4.4.tar.bz2  /usr/local/src
tar -xjvf  httpd-2.4.4.tar.bz2
(2)编译安装httpd
cd httpd-2.4.4
./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --enable-so --enable-rewirte --enable-ssl --enable-cgi --enable-cgid --enable-modules=most --enable-mods-shared=most --enable-mpms-shared=all --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util
解释:
--enable-so:支持动态共享模块,如果支持php将不能与apache一起工作。必须要有
--enable-ssl:启用ssl功能,如果不启用将无法使用https
--enable-mpms-shared=all:prefork、worker、event
--with-mpm=event:event为默认
 --enable-rewrite:支持URL重写
--enable-cgi :支持cgi
--enable-cgid:httpd使用event或者worker得启用被线程方式访问
--enable-modules=most :启用大多数模块
--enable-mods-shared=most:启用大多数共享模块
(3)setenforce 0 关掉selinux。(临时关闭)
永久关闭 vim /etc/selinux/config

二、后续操作
1、启动httpd
两种方法:第一种、/usr/local/apache/bin/apachectl start
第二种方法:先修改http.pid文件位置打开配置文件增加一行
vim /etc/httpd/httpd.conf    增加PidFile “/var/run/httpd.pid”

Linux下Apache的安装与配置

为了启动httpd更加方便,
#!/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)
start
;;
  stop)
stop
;;
  status)
        status -p ${pidfile} $httpd
RETVAL=$?
;;
  restart)
stop
start
;;
  condrestart)
if [ -f ${pidfile} ] ; then
stop
start
fi
;;
  reload)
        reload
;;
  graceful|help|configtest|fullstatus)
$apachectl $@
RETVAL=$?
;;
  *)
echo $"Usage: $prog {start|stop|restart|condrestart|reload|status|fullstatus|graceful|help|configtest}"
exit 1
esac


exit $RETVAL
将以上代码加入到vim /etc/init.d/httpd中
而后为此脚本赋予执行权限:
 chmod +x /etc/rc.d/init.d/httpd
加入服务列表:
 chkconfig --add httpd
给3,5启动
chkconfig --level  3,5 httpd on
最后加路径
将 export PATH=$PATH:/usr/local/apache/bin
vim /etc/profile.d/httpd.sh完成后重新登录就可以了。推荐使用第二种方法
