c++11实现简易muduo网络库
根目录的build.sh和example的Makefile中把项目路径修改为自己当前项目的路径，然后执行如下代码生成动态链接库
sudo ./build.sh
cd examle
make
./EchoServer
如果执行./EchoServer报如下错误，表示找不到动态链接库
./EchoServer: error while loading shared libraries: libmymuduo.so: cannot open shared object file: No such file or directory
则需要执行下面代码临时指定动态链接库的目录
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:你项目的目录/lib
