nginx：为识别的服务

Linux运维专家群 QQ：419858299 技术成就梦想，欢迎小伙伴加入

当安装完nginx后，我们要使用service nginx start来启动nginx服务，输入命令之后我们发现会出现如下错误 nginx:未被识别的服务

这个报错的意思就是nginx的启动项没有放到/etc/init.d/（类似与windows中的注册表）中。如下就是解决的办法：

1. vim /etc/init.d/nginx #创建nginx的启动，停止，重启的脚本，需要添加如下内容。

#!/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

start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
echo -n $"Starting $prog: "

echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}

stop() {
echo -n $"Stopping $prog: "
killproc $prog -TERM
retval=$?
if [ $retval -eq 0 ]; then
if [ "$CONSOLETYPE" != "serial" ]; then
echo -en "\\033[16G"
fi
while rh_status_q
do
sleep 1
echo -n $"."
done
rm -f $lockfile
fi
echo
return $retval
}

restart() {
configtest || return $?
stop
start
}

reload() {
configtest || return $?
echo -n $"Reloading $prog: "
killproc $nginx -HUP
sleep 1
RETVAL=$?
echo
}

configtest() {
$nginx -t -c $NGINX_CONF_FILE
}

rh_status() {
status $prog
}

rh_status_q() {
rh_status >/dev/null 2>&1
}

# Upgrade the binary with no downtime.
upgrade() {
local pidfile="/var/run/${prog}.pid"
local oldbin_pidfile="${pidfile}.oldbin"

configtest || return $?
echo -n $"Staring new master $prog: "
killproc $nginx -USR2

killproc -p ${oldbin_pidfile} -TERM
sleep 1

echo
return 0
else
echo $"Something bad happened, manual intervention required, maybe restart?"
return 1
fi
}

case "$1" in

rh_status_q && exit 0

echo $"Usage: $0 {start|stop|reload|configtest|status|force-reload|upgrade|restart}"
exit 2
esac

保存并退出

2. chmod +x /etc/init.d/nginx #给予相关的权限

3. /sbin/chkconfig nginx on #添加到开机启动

4. /sbin/chkconfig --list nginx 查看开机启动菜单

5. 如上操作之后就可以使用service nginx start,service nginx stop,service nginx restart等命令、

如上就是解决nginx：未被识别的服务的错误。。。
