在添加nginx服务之后，大家会希望开机伴随启动nginx，避免手动路径输入启动；
nginx官方提供了启动脚本:https://www.nginx.com/resources/wiki/start/topics/examples/redhatnginxinit/
nginx 安装可以参考【Web】Nginx下载与安装
配置步骤
1、添加nginx服务，进入/etc/init.d/目录，新添加nginx脚本文件，内容就是官方起启动脚本（/etc/init.d/nginx），如下：
?1 #!/bin/sh ?2 # ?3 # nginx - this script starts and stops the nginx daemon ?4 # ?5 # chkconfig: ??- 85 15 ?6 # description: ?NGINX is an HTTP(S) server, HTTP(S) reverse \ ?7 # ??????????????proxy and IMAP/POP3 proxy server ?8 # processname: nginx ?9 # config: ?????/etc/nginx/nginx.conf 10 # config: ?????/etc/sysconfig/nginx 11 # pidfile: ????/var/run/nginx.pid 12 ?13 # Source function library. 14 . /etc/rc.d/init.d/functions 15 ?16 # Source networking configuration. 17 . /etc/sysconfig/network 18 ?19 # Check that networking is up. 20 [ "$NETWORKING" = "no" ] && exit 0 21 ?22 nginx="/usr/sbin/nginx" 23 prog=$(basename $nginx) 24 ?25 NGINX_CONF_FILE="/etc/nginx/nginx.conf" 26 ?27 [ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx 28 ?29 lockfile=/var/lock/subsys/nginx 30 ?31 make_dirs() { 32 ???# make required directories 33 ???user=`$nginx -V 2>&1 | grep "configure arguments:.*--user=" | sed ‘s/[^*]*--user=\([^ ]*\).*/\1/g‘ -` 34 ???if [ -n "$user" ]; then 35 ??????if [ -z "`grep $user /etc/passwd`" ]; then 36 ?????????useradd -M -s /bin/nologin $user 37 ??????fi 38 ??????options=`$nginx -V 2>&1 | grep ‘configure arguments:‘` 39 ??????for opt in $options; do 40 ??????????if [ `echo $opt | grep ‘.*-temp-path‘` ]; then 41 ??????????????value=`echo $opt | cut -d "=" -f 2` 42 ??????????????if [ ! -d "$value" ]; then 43 ??????????????????# echo "creating" $value 44 ??????????????????mkdir -p $value && chown -R $user $value 45 ??????????????fi 46 ??????????fi 47 ???????done 48 ????fi 49 } 50 ?51 start() { 52 ????[ -x $nginx ] || exit 5 53 ????[ -f $NGINX_CONF_FILE ] || exit 6 54 ????make_dirs 55 ????echo -n $"Starting $prog: " 56 ????daemon $nginx -c $NGINX_CONF_FILE 57 ????retval=$? 58 ????echo 59 ????[ $retval -eq 0 ] && touch $lockfile 60 ????return $retval 61 } 62 ?63 stop() { 64 ????echo -n $"Stopping $prog: " 65 ????killproc $prog -QUIT 66 ????retval=$? 67 ????echo 68 ????[ $retval -eq 0 ] && rm -f $lockfile 69 ????return $retval 70 } 71 ?72 restart() { 73 ????configtest || return $? 74 ????stop 75 ????sleep 1 76 ????start 77 } 78 ?79 reload() { 80 ????configtest || return $? 81 ????echo -n $"Reloading $prog: " 82 ????killproc $nginx -HUP 83 ????RETVAL=$? 84 ????echo 85 } 86 ?87 force_reload() { 88 ????restart 89 } 90 ?91 configtest() { 92 ??$nginx -t -c $NGINX_CONF_FILE 93 } 94 ?95 rh_status() { 96 ????status $prog 97 } 98 ?99 rh_status_q() {100 ????rh_status >/dev/null 2>&1101 }102 103 case "$1" in104 ????start)105 ????????rh_status_q && exit 0106 ????????$1107 ????????;;108 ????stop)109 ????????rh_status_q || exit 0110 ????????$1111 ????????;;112 ????restart|configtest)113 ????????$1114 ????????;;115 ????reload)116 ????????rh_status_q || exit 7117 ????????$1118 ????????;;119 ????force-reload)120 ????????force_reload121 ????????;;122 ????status)123 ????????rh_status124 ????????;;125 ????condrestart|try-restart)126 ????????rh_status_q || exit 0127 ????????????;;128 ????*)129 ????????echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"130 ????????exit 2131 esac2、修改脚本内容
a、在脚本中11行，新增pid文件位置，可以在nginx运行时查看，命令：find / -name nginx.pid
1 pidfile="/data/soft/nginx/logs/nginx.pid"
b、在脚本中22行（nginx="/usr/sbin/nginx"）修改nginx脚本文件位置
1 nginx="/data/soft/nginx/sbin/nginx"
c、在脚本中25行（NGINX_CONF_FILE="/etc/nginx/nginx.conf"）修改nginx配置文件位置
1 NGINX_CONF_FILE="/data/soft/nginx/conf/nginx.conf"
3、给脚本增加可执行权限，命令：chmod a+x /etc/init.d/nginx
到这一步服务已经添加好了
a、服务启动：service nginx start
b、服务停止：service nginx stop
c、服务重新加载：service nginx reload
4、添加开机启动项
a、添加命令：chkconfig --add /etc/init.d/nginx
b、查看启动项，命令：chkconfig --list
nginx启动项状态：nginx 0:off 1:off 2:off 3:off 4:off 5:off 6:off
c、需要设置nginx启动命令：chkconfig nginx on
nginx启动项状态：nginx 0:off 1:off 2:on 3:on 4:on 5:on 6:off
d、关闭命令为：chkconfig nginx on
e、删除命令为：chkconfig --del nginx
5、执行命令reboot，重启服务器即可验证nginx开机启动
