libevent安装
libevent安装
libevent是个程序库，它将Linux的epoll、BSD类操作系统的kqueue等事件处理功能封装成统一的
接口。即使对服务器的连接数增加，也能发挥O(1)的性能。memcached使用这个libevent库。在安装libevent之前，
先检查系统中是否已经安装过libevent，如果卸载请使用
命令：rpm -e libevent版本 --nodeps
1、下载
使用wget命令获取libevent安装包。或者直接下载源码包（本人直接下载的，使用wget命令的url请自己查询）。
2、将下载的.tar.gz格式的包上传到linux系统下。我放在了root目录下。执行如下命令。
# tar zxvf libevent-2.0.16-stable.tar.gz
# cd libevent-2.0.16-stable/
# ./configure –prefix=/usr
# make
# make install
3.测试libevent是否安装成功：
# ls -al /usr/lib | grep libevent
