## 安装Nginx
## 为优化性能，可以安装 google 的 tcmalloc ，之前己经安装过了
## 所以我们编译 Nginx 时，加上参数 --with-google_perftools_module
## 然后在启动nginx前需要设置环境变量 export LD_PRELOAD=/usr/local/lib/libtcmalloc.so
## 加上 -O2 参数也能优化一些性能
##
## 默认的Nginx编译选项里居然是用 debug模式的(-g参数)，在 auto/cc/gcc 文件最底下，去掉那个 -g 参数
## 就是将  CFLAGS="$CFLAGS -g"  修改为   CFLAGS="$CFLAGS"   或者直接删除这一行
