是一个高性能的 Web 和反向代理服务器等许多优越的特性。
- 作为 Web 服务器：相比 Apache，Nginx 使用更少的资源，支持更多的并发连接，体现更高的效率，这点使 Nginx 尤其受到虚拟主机提供商的欢迎。能够支持高达 50,000 个并发连接数的响应，感谢 Nginx 为我们选择了 epoll and kqueue 作为开发模型.
- 作为负载均衡服务器：Nginx 既可以在内部直接支持 Rails 和 PHP，也可以支持作为 HTTP代理服务器 对外进行服务。Nginx 用 C 编写, 不论是系统资源开销还是 CPU 使用效率都比 Perlbal 要好的多。
- 作为邮件代理服务器: Nginx 同时也是一个非常优秀的邮件代理服务器（最早开发这个产品的目的之一也是作为邮件代理服务器），Last.fm 描述了成功并且美妙的使用经验。
- Nginx 安装非常的简单，配置文件 非常简洁（还能够支持perl语法），Bugs非常少的服务器: Nginx 启动特别容易，并且几乎可以做到7*24不间断运行，即使运行数个月也不需要重新启动。你还能够在 不间断服务的情况下进行软件版本的升级。
负载均衡配置
以下是http和https Nginx负载均衡的配置。仅限后台接口使用。不包含静态文件的访问。

Suse下开机启动脚本
#! /bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
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() {
kill -INT `cat $PIDFILE` || echo -n "nginx not running"
}
do_reload() {
kill -HUP `cat $PIDFILE` || 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
操作步骤：
拷贝以上脚本信息，在suse linux的etc/init.d/目录下使用以下命令。
vi nginx #添加nginx启动脚本，将以上内容拷贝进去。
添加nginx服务
chkconfig --add nginx
设置启动等级
chkconfig -level 2345 nginx on
验证:
service nginx start
nginx already running
表示添加服务成功。
