Tornado的确很给力，知乎、Facebook一直在用。不过Tornado也有自己的局限性，比如它就没有实现完整的HTTP协议，甚至一些REST方法都不支持。不过这也难为它了，本来就是一个Web Framework顺便兼职干一点Web Server的事情而已，有就不错了。好在Tornado现在有了好伙伴Nginx，像HTTPS，负载均衡，静态文件这种破事都可以交给Nginx去处理了。
下载
从源代码编译安装Nginx需要处理一些依赖Nginx官网PCRE官网ZLib官网 下载好之后解压至同一根目录下。
编译
$ ./configure --sbin-path=/usr/local/nginx/nginx --conf-path=/usr/local/nginx/nginx.conf --pid-path=/usr/local/nginx/nginx.pid --with-http_ssl_module --with-pcre=../pcre-8.38 --with-zlib=../zlib-1.2.8 --with-openssl=../openssl-1.0.2g#上面只是为了好看....$ ./configure --sbin-path=/usr/local/nginx/nginx --conf-path=/usr/local/nginx/nginx.conf --pid-path=/usr/local/nginx/nginx.pid --with-http_ssl_module --with-pcre=../pcre-8.38 --with-zlib=../zlib-1.2.8 --with-openssl=../openssl-1.0.2g$ make -j8 && sudo make install
需要注意的是，Mac下和Linux下默认生成的目录是不一样的。 nginx运行一般要求root权限。 nginx命令行参数相当简单，因为功夫全在配置文件里了……。
#启动Nginx实例$ nginx#使用指定的配置文件启动nginx$ nginx -c <conf_file>#向Nginx发出信号$ nginx -s [stop| quit| reopen| reload]
