Nginx 是一个很强大的高性能Web和反向代理服务器。虽然使用命令行可以对nginx进行各种操作,比如启动等,但是还是根据不太方便。下面介绍在CentOS下安装后,如何设置开机自启动。
首先,在linux系统的/etc/init.d/目录下创建nginx文件,使用如下命令:
vim /etc/init.d/nginx
在脚本中添加如下命令:
#!/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.
[ "$NETWORKING" = "no" ] && exit 0
#Nginx命令路径
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
#Nginx配置文件路径
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
# make required directories
user=`$nginx -V 2>&1 | grep "configure arguments:.*--user=" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
if [ -n "$user" ]; then
if [ -z "`grep $user /etc/passwd`" ]; then
useradd -M -s /bin/nologin $user
fi
options=`$nginx -V 2>&1 | grep 'configure arguments:'`
for opt in $options; do
if [ `echo $opt | grep '.*-temp-path'` ]; then
value=`echo $opt | cut -d "=" -f 2`
if [ ! -d "$value" ]; then
# echo "creating" $value
mkdir -p $value && chown -R $user $value
fi
fi
done
fi
}
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
make_dirs
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 $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}
restart() {
configtest || return $?
stop
sleep 1
start
}
reload() {
configtest || return $?
echo -n $"Reloading $prog: "
killproc $nginx -HUP
RETVAL=$?
echo
}
force_reload() {
restart
}
configtest() {
$nginx -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
esac
保存脚本文件后设置文件的执行权限:
chmod a+x /etc/init.d/nginx
然后,就可以通过该脚本对nginx服务进行管理了:
/etc/init.d/nginx start
/etc/init.d/nginx stop
使用chkconfig进行管理
上面的方法完成了用脚本管理nginx服务的功能,但是还是不太方便,比如要设置nginx开机启动等。这时可以使用chkconfig来设置。
先将nginx服务加入chkconfig管理列表:
chkconfig --add /etc/init.d/nginx
加完这个之后,就可以使用service对nginx进行启动,重启等操作了。
service nginx start
service nginx stop
设置终端模式开机启动:
chkconfig nginx on
如果服务启动时,提示以下内容:
May 22 17:48:57 gongxm systemd[1]: Starting SYSV: NGINX is an HTTP(S) serve.....
May 22 17:48:57 gongxm systemd[1]: PID file /var/run/nginx.pid not readable...t.
May 22 17:48:57 gongxm systemd[1]: Failed to start SYSV: NGINX is an HTTP(S...r.
May 22 17:48:57 gongxm systemd[1]: Unit nginx.service entered failed state.
May 22 17:48:57 gongxm systemd[1]: nginx.service failed.
解决方案:
1. 修改nginx的配置文件: nginx.conf
把 "pid logs/nginx.pid;" 这句前面的#去掉
2.执行以下命令
systemctl daemon-reload
3.再次尝试启动服务
