linux 安装 nginx，并且注册成一个服务

* 一键安装四个依赖

yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel

* 安装 nginx【如果报：-bash: wget: command not found，先安装 wget：yum -y install wget】

$ cd /usr/local/
$ wget http://nginx.org/download/nginx-1.10.3.tar.gz
$ tar -zxvf nginx-1.10.3.tar.gz
$ cd nginx-1.10.3 
$ ./configure
$ make && make install

* 启动 nginx

/usr/local/nginx/sbin/nginx

* 查看是否启动：

ps aux | grep nginx   //能看到 nginx 进程表示启动成功

或者直接访问：

curl 127.0.0.1:80

看到 nginx 欢迎页的 html 代码表示成功

* nginx 的启动停止重启操作：

启动：/usr/local/nginx/sbin/nginx
停止：/usr/local/nginx/sbin/nginx -s stop
重启：/usr/local/nginx/sbin/nginx -s reload

* 设置 nginx 开机自启

vi /etc/rc.local
底部加：
/usr/local/nginx/sbin/nginx

* 把 nginx 配置成一个服务：

vi /etc/init.d/nginx

* 服务脚本：

复制代码

#!/bin/sh
#chkconfig: - 85 15
 
PATH=/usr/local/nginx/sbin
DESC="nginx daemon"
NAME=nginx
DAEMON=/usr/local/nginx/sbin/$NAME
CONFIGFILE=/usr/local/nginx/conf/$NAME.conf
PIDFILE=/usr/local/nginx/logs/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
 
set -e
[ -x "$DAEMON" ] || exit 0
 
do_start() {
$DAEMON -c $CONFIGFILE || echo -n "nginx already running"
}
 
do_stop() {
$DAEMON -s stop || echo -n "nginx not running"
}
 
do_reload() {
$DAEMON -s reload || echo -n "nginx can't reload"
}
 
case "$1" in
start)
echo -n "Starting $DESC: $NAME"
do_start
echo "."
;;
stop)
echo -n "Stopping $DESC: $NAME"
do_stop
echo "."
;;
reload|graceful)
echo -n "Reloading $DESC configuration..."
do_reload
echo "."
;;
restart)
echo -n "Restarting $DESC: $NAME"
do_stop
do_start
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2
exit 3
;;
esac
exit 0

复制代码​

保存后赋予权限：

chmod 777 nginx

添加服务：

chkconfig --add nginx

重开一下终端窗口，然后再测试：（有时候要等一会才生效，具体原因不明）

启动：systemctl start nginx.service
停止：systemctl stop nginx.service
重启：systemctl restart nginx.service
