Debian/Ubuntu: apt-get install libevent-dev Redhat/Centos: yum install libevent-devel 。
经实践，它本质上是使用了这个libevent，并不是libevent-devel,但编译时应该需要这个libevent-devel库,libevent-devel在用yum安装时会把libevent库给以依赖的形式下载下来，于是运行正常。
# rpm -q libevent-devel --requires     /usr/bin/env   libevent = 1.4.13-4.el6 libevent-1.4.so.2()(64bit)   libevent-doc = 1.4.13-4.el6 libevent-headers = 1.4.13-4.el6 libevent_core-1.4.so.2()(64bit)   libevent_extra-1.4.so.2()(64bit)   rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(FileDigests) <= 4.6.0-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 rpmlib(PayloadIsXz) <= 5.2-1 # rpm -qf /usr/lib64/libevent-1.4.so.2 libevent-1.4.13-4.el6.x86_64 # ldd /usr/local/memcached/bin/memcached         linux-vdso.so.1 =>  (0x00007ffd5b31c000)         libhugetlbfs.so => /usr/lib64/libhugetlbfs.so (0x00007f49105d1000)         libevent-1.4.so.2 => /usr/lib64/libevent-1.4.so.2 (0x00007f49103b6000)         librt.so.1 => /lib64/librt.so.1 (0x0000003772000000)         libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003771800000)         libc.so.6 => /lib64/libc.so.6 (0x0000003771400000)         libdl.so.2 => /lib64/libdl.so.2 (0x0000003771c00000)         libnsl.so.1 => /lib64/libnsl.so.1 (0x0000003eabe00000)         libresolv.so.2 => /lib64/libresolv.so.2 (0x0000003775000000)         /lib64/ld-linux-x86-64.so.2 (0x0000003771000000)

验证libevent-devel是和libevent包是有yum有依赖的：
