    4.编译并安装

    [root@nginx nginx-1.4.2]# make && make install

    5.为nginx提供SysV init脚本

    [root@nginx ~]# cat /etc/init.d/nginx #!/bin/sh # # nginx - this script starts and stops the nginx daemon # # chkconfig:  - 85 15 # description: Nginx is an HTTP(S) server, HTTP(S) reverse \ #        proxy and IMAP/POP3 proxy server # processname: nginx # config:   /etc/nginx/nginx.conf # config:   /etc/sysconfig/nginx # pidfile:   /var/run/nginx.pid # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ "$NETWORKING" = "no" ] && exit 0 nginx="/usr/sbin/nginx" prog=$(basename $nginx) NGINX_CONF_FILE="/etc/nginx/nginx.conf" [ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx lockfile=/var/lock/subsys/nginx make_dirs() {   # make required directories   user=`nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`   options=`$nginx -V 2>&1 | grep 'configure arguments:'`   for opt in $options; do     if [ `echo $opt | grep '.*-temp-path'` ]; then       value=`echo $opt | cut -d "=" -f 2`       if [ ! -d "$value" ]; then         # echo "creating" $value         mkdir -p $value && chown -R $user $value       fi     fi   done } start() {   [ -x $nginx ] || exit 5   [ -f $NGINX_CONF_FILE ] || exit 6   make_dirs   echo -n $"Starting $prog: "   daemon $nginx -c $NGINX_CONF_FILE   retval=$?   echo   [ $retval -eq 0 ] && touch $lockfile   return $retval } stop() {   echo -n $"Stopping $prog: "   killproc $prog -QUIT   retval=$?   echo   [ $retval -eq 0 ] && rm -f $lockfile   return $retval } restart() {   configtest || return $?   stop   sleep 1   start } reload() {   configtest || return $?   echo -n $"Reloading $prog: "   killproc $nginx -HUP   RETVAL=$?   echo } force_reload() {   restart } configtest() {  $nginx -t -c $NGINX_CONF_FILE } rh_status() {   status $prog } rh_status_q() {   rh_status >/dev/null 2>&1 } case "$1" in   start)     rh_status_q && exit 0     $1     ;;   stop)     rh_status_q || exit 0     $1     ;;   restart|configtest)     $1     ;;   reload)     rh_status_q || exit 7     $1     ;;   force-reload)     force_reload     ;;   status)     rh_status     ;;   condrestart|try-restart)     rh_status_q || exit 0       ;;   *)     echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"     exit 2 esac

    6.为此脚本赋予执行权限

    [root@nginx ~]# chmod +x /etc/init.d/nginx

    7.添加至服务管理列表,并让其开机自动启动

    [root@nginx ~]# chkconfig --add nginx [root@nginx ~]# chkconfig nginx on [root@nginx ~]# chkconfig nginx --list nginx       0:关闭  1:关闭  2:启用  3:启用  4:启用  5:启用  6:关闭

    8.启动nginx

    [root@nginx ~]# service nginx start 正在启动 nginx:                      [确定]

    9.查看一下端口

    [root@nginx ~]# netstat -ntlp | grep :80 tcp    0   0 0.0.0.0:80         0.0.0.0:*          LISTEN   3889/nginx
