mongols

mongols 是一个 C++ 库。

依赖：

• linux

• pcre-devel

• hiredis-devel

• zlib-devel

• openssl-devel

• curl-devel

sudo yum install pcre-devel zlib-devel openssl-devel hiredis-devel libcurl-devel

或者：

sudo apt-get install libpcre3-dev zlib1g-dev libssl-dev libhiredis-dev libcurl4-openssl-dev

特性：

epoll or epoll + multi-threading

• tcp sever

• http server

• websocket server

• web server

• leveldb server

• lua server

• sqlite server

• utils

安装：

make clean && make -j2 && sudo make install && sudo ldconfig

使用：

pkg-config --libs --cflags mongols
