获取nginx的性能状态信息

在编译nginx过程中需启用–with-http_stub_status_module参数

查看当前安装Nginx的版本与配置信息

[root@localhost conf]# export PATH=/usr/local/nginx/sbin/:$PATH
[root@localhost conf]# nginx -V
nginx version: nginx/1.4.0
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC)
TLS SNI support enabled
configure arguments: –prefix=/usr/local/nginx –with-http_stub_status_module
–with-http_ssl_module –with-pcre=../pcre-8.32/
–with-zlib=../zlib-1.2.8 –with-openssl=../openssl-1.0.1e
[root@localhost conf]#

添加

location /status {
stub_status on;
access_log  off;
allow 192.168.244.0/24;
deny all;
}

服务器文件列表
[root@localhost conf]# pwd
/usr/local/nginx/conf
[root@localhost conf]# mkdir ../html/pub
[root@localhost conf]# touch ../html/pub/hello.txt

location /pub   {
autoindex on;
autoindex_exact_size on;
autoindex_localtime off;
}

检测配置文件正确性

[root@localhost conf]# nginx -t -c /usr/local/nginx/conf/nginx.conf
nginx: [emerg] unexpected end of file, expecting “}” in /usr/local/nginx/conf/nginx.conf:131
