LAMP平台的的构建、加速及压力测试

准备工作
环境:
RedHat 5.8 (我这里用的是redhat5.8的版本,可以根据自己的情况灵活进行选择其它的发行版,但是编译环境和依赖的库一定要具备)

软件:

一、编译安装apache
1、解决依赖关系
(1) 编译安装apr
# tar xf apr-1.4.6.tar.bz2
# cd apr-1.4.6
# ./configure --prefix=/usr/local/apr
# make && make install

(2) 编译安装apr-util
# tar xf 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) 编译安装pcre
# tar xf pcre-8.33.tar.gz
# cd pcre-8.33
# ./configure --prefix=/usr/local/pcre
# make && make install

2、编译安装httpd-2.4.12
(1) 首先下载httpd-2.4.12到本地,然后进行如下操作
# tar xf httpd-2.4.12tar.bz2
# cd httpd-2.4.12
#./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --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-modules=most --enable-mpms-shared=most--with-mpm=event
#make && make install

(2)修改httpd的主配置文件,设置其Pid文件的路径
编辑/etc/httpd/httpd.conf,添加如下行即可:
PidFile  "/var/run/httpd.pid"

注意:如果缺少这一步,则后面的SysV风格的脚本无法正常工作!
(3) 提供SysV服务脚本/etc/rc.d/init.d/httpd,内容如下
#!/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)
    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

这个脚本的主要功能就是可以实现像
#service httpd {start|restart|stop|status|reload}

之类的功能
 
而后为此脚本赋予执行权限:
# chmod+x /etc/rc.d/init.d/httpd

注意:必须给这个脚本执行权限,否则服务无法正常执行!
加入服务列表:
#chkconfig --add httpd
#chkconfig --level 35 httpd on

接下来就可以启动服务进行测试了。
