安装：
依赖的软件包：
gcc gcc-c++ autoconf automakezlib zlib-devel openssl opensll-devel pcre pcre-devel
到官方网站上下载nginx包：
解压:
tar -zxf nginx-x.x.tar.gz
安装三步走：./configure------- make------make install
./configure --prefix=/usr/local/nginx --sbin-path=/usr/local/nginx/sbin/nginx \--error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx/nginx.pid \--lock-path=/var/lock/nginx.lock --user=nginx --group=nginx --with-http_ssl_module \--with-http_gzip_static_module --with-http_ssl_module --http-log-path=/var/log/nginx/access.log \--http-client-body-temp-path=/var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/\ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \
[root@localhost ~]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf 启动nginx
查看nginx是否启动：

/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf #检查配置文件的正确性。
nginx.conf 配置文件定义：

kill -QUIT nginx主进程号kill -QUIT 7802 或者 kill -QUIT `cat /var/run/nginx/nginx.pid`
2.快速停止nginx：
kill -TERM ngixID 或者 kill -INT nginxID nginxID-----主进程号[root@localhost ~]# kill -TERM 7886[root@localhost ~]# [root@localhost ~]# ps -ef | grep nginxroot 7900 3696 0 10:04 pts/3 00:00:00 grep nginx
3.强制停止nginx：
pkill -9 nginx
4.平滑启动nginx：
kill -HUP nginxID
Nginx信号控制说明：
TERM,INT 快速关闭nginxQUIT 从容关闭；HUP 平滑启动；USR1 重新打开日志文件（日志切割很有用）USR2 平滑升级可执行程序。WINCH 从容关闭工作。升级新版本关闭旧版本时用WINCH。
检查nginx配置文件的正确与否：
/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf[root@localhost ~]# /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.confthe configuration file /usr/local/nginx/conf/nginx.conf syntax is okconfiguration file /usr/local/nginx/conf/nginx.conf test is successful[root@localhost ~]#
