本人在centos下安装zeromq
1.下载最新版的zeromq
http://download.zeromq.org/
2 解压
tar -xvf zeromq-3.1.0-beta.tar.gz
3 运行configure
./configure --prefix=/data/zeromq (prefix 指定安装目录)
出现问题：
configure: error: Package requirements (libsodium >= 0.0.0) were not met 参考：http://www.cnblogs.com/jim-hwg/p/4952349.html
这里最好使用
libsodium-1.0.3 小于等于版本。
4. make
5. make install
