centos/rhel下实现nginx自启动脚本实例
投稿：shichen2014
这篇文章主要介绍了centos/rhel下实现nginx自启动脚本,需要的朋友可以参考下
通常在centos、rhel的OS下，我们大多是通过chkconfig来管理服务，比如开机自动启动服务之类。
这里给大家介绍一个很好用的nginx启动脚本。以及简单的使用，如下：
1. 执行如下命令：
vim /etc/init.d/nginxd
2.输入如下内容：
注意：该文件中的如下几个变量，都需要根据你实际的目录来改写。
nginx="/usr/local/nginx/sbin/nginx" ##nginx的可执行文件路径
lockfile="/var/nginx/nginx.lock" ##需要先创建/var/nginx目录
NGINX_CONF_FILE="/etc/nginx/nginx.conf" ##需要先创建该配置文件
#!/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
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
sysconfig="/etc/sysconfig/$prog"
lockfile="/var/nginx/nginx.lock"
pidfile="/var/nginx/${prog}.pid"
NGINX_CONF_FILE="/etc/nginx/nginx.conf"
[ -f $sysconfig ] && . $sysconfig
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
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 -p $pidfile $prog
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}
restart() {
configtest_q || return 6
stop
start
}
reload() {
configtest_q || return 6
echo -n $"Reloading $prog: "
killproc -p $pidfile $prog -HUP
echo
}
configtest() {
$nginx -t -c $NGINX_CONF_FILE
}
configtest_q() {
$nginx -t -q -c $NGINX_CONF_FILE
}
rh_status() {
status $prog
}
rh_status_q() {
rh_status >/dev/null 2>&1
}
# Upgrade the binary with no downtime.
upgrade() {
local oldbin_pidfile="${pidfile}.oldbin"
configtest_q || return 6
echo -n $"Upgrading $prog: "
killproc -p $pidfile $prog -USR2
retval=$?
sleep 1
if [[ -f ${oldbin_pidfile} && -f ${pidfile} ]]; then
killproc -p $oldbin_pidfile $prog -QUIT
success $"$prog online upgrade"
echo
return 0
else
failure $"$prog online upgrade"
echo
return 1
fi
}
# Tell nginx to reopen logs
reopen_logs() {
configtest_q || return 6
echo -n $"Reopening $prog logs: "
killproc -p $pidfile $prog -USR1
retval=$?
echo
return $retval
}
case "$1" in
start)
rh_status_q && exit 0
$1
;;
stop)
rh_status_q || exit 0
$1
;;
restart|configtest|reopen_logs)
$1
;;

rh_status_q || exit 7

*)
echo $"Usage: $0 {start|stop|reload|configtest|status|force-reload|upgrade|restart|reopen_logs}"
exit 2
esac
保存完毕之后，可以执行以下命令来启动nginx
chmod 777 /etc/init.d/nginxd /etc/init.d/nginxd start
3. 配置开机启动
执行以下命令：
chkconfig nginxd on
可以以下命令查看是否成功
chkconfig --list | grep nginxd
