一、方法一（推荐）
1、创建脚本
1）centos
vim /usr/lib/systemd/system/nginx.service
[Unit] Description=The nginx HTTP and reverse proxy server After=network.target remote-fs.target nss-lookup.target [Service] Type=forking PIDFile=/run/nginx.pid # Nginx will fail to start if /run/nginx.pid already exists but has the wrong # SELinux context. This might happen when running `nginx -t` from the cmdline. # https://bugzilla.redhat.com/show_bug.cgi?id=1268621 ExecStartPre=/usr/bin/rm -f /run/nginx.pid ExecStartPre=/usr/local/sbin/nginx -t ExecStart=/usr/local/sbin/nginx ExecReload=/bin/kill -s HUP $MAINPID KillSignal=SIGQUIT TimeoutStopSec=5 KillMode=process PrivateTmp=true [Install] WantedBy=multi-user.target
根据nginx编译情况修改下面三项配置
ExecStartPre=/usr/bin/rm -f /run/nginx.pid ExecStartPre=/usr/local/sbin/nginx -t ExecStart=/usr/local/sbin/nginx
2）ubuntu
vim /lib/systemd/system/nginx.service
[Unit] Description=The nginx HTTP and reverse proxy server After=network.target remote-fs.target nss-lookup.target [Service] Type=forking PIDFile=/run/nginx.pid # Nginx will fail to start if /run/nginx.pid already exists but has the wrong # SELinux context. This might happen when running `nginx -t` from the cmdline. # https://bugzilla.redhat.com/show_bug.cgi?id=1268621 ExecStartPre=/bin/rm -f /run/nginx.pid ExecStartPre=/usr/local/sbin/nginx -t ExecStart=/usr/local/sbin/nginx ExecReload=/bin/kill -s HUP $MAINPID KillSignal=SIGQUIT TimeoutStopSec=5 KillMode=process PrivateTmp=true [Install] WantedBy=multi-user.target
根据nginx编译情况修改下面三项配置
ExecStartPre=/bin/rm -f /run/nginx.pid ExecStartPre=/usr/local/sbin/nginx -t ExecStart=/usr/local/sbin/nginx
2、修改权限
1）centos
sudo chmod +x /usr/lib/systemd/system/nginx.service
2）ubuntu
sudo chmod +x /lib/systemd/system/nginx.service
3、开机启动
sudo systemctl enable nginx.service
4、更多控制命令
systemctl start nginx.service #启动nginx服务 systemctl enable nginx.service #设置开机自启动 systemctl disable nginx.service #停止开机自启动 systemctl status nginx.service #查看服务当前状态 systemctl restart nginx.service #重新启动服务 systemctl list-units --type=service #查看所有已启动的服务
二、方法二
1、关闭nginx
2、创建启动脚本
vim /etc/init.d/nginx
3、写入以下代码
#!/bin/sh
# Name:nginx service
# nginx - this script starts and stops the nginx daemon
#
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /usr/local/nginx/conf/nginx.conf
# pidfile: /usr/local/nginx/logs/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
NGINX_DAEMON_PATH="/usr/local/sbin/nginx"
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
NGINX_LOCK_FILE="/var/lock/subsys/nginx"
prog=$(basename $NGINX_DAEMON_PATH)
start() {
[ -x $NGINX_DAEMON_PATH ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
echo -n $"Starting $prog: "
daemon $NGINX_DAEMON_PATH -c $NGINX_CONF_FILE
retval=$?
echo
[ $retval -eq 0 ] && touch $NGINX_LOCK_FILE
return $retval
}
stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $NGINX_LOCK_FILE
return $retval
}
restart() {
configtest || return $?
stop
start
}
reload() {
configtest || return $?
echo -n $"Reloading $prog: "
killproc $NGINX_DAEMON_PATH -HUP
RETVAL=$?
echo
}
force_reload() {
restart
}
configtest() {
$NGINX_DAEMON_PATH -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
esac4、给启动脚本增加执行权限
chmod +x /etc/init.d/nginx
