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>&1
101 }
102
103 case "$1" in
104 start)
105 rh_status_q && exit 0
106 $1
107 ;;
108 stop)
109 rh_status_q || exit 0
110 $1
111 ;;
112 restart|configtest)
113 $1
114 ;;
115 reload)
116 rh_status_q || exit 7
117 $1
118 ;;
119 force-reload)
120 force_reload
121 ;;
122 status)
123 rh_status
124 ;;
125 condrestart|try-restart)
126 rh_status_q || exit 0
127 ;;
128 *)
129 echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
130 exit 2
131 esac
2、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
