libz.so.1: cannot open shared object file: No such file or directory
还是之前那个问题，yum安装的时候报错
yum -y install net-snmp net-snmp-devel curl-devel java-1.8.0-openjdk java-1.8.0-openjdk-devel OpenIPMI-devel libssh2-devel
报错信息是

rpm -qa|grep zlib的时候有两个版本，卸载旧的版本之后，出现如题报错，我就纳闷了，不是有这个包吗
再次查看
# rpm -qa|grep zlib zlib-1.2.7-15.el7.i686 zlib-devel-1.2.7-17.el7.x86_64
版本也在，按照网上说的重新安装是不可能了，查找这个文件
# find / -name libz.so.1 /usr/lib/libz.so.1 /usr/local/lib/libz.so.1
libz.so.1文件还在，我之前编译安装过zlib
所以做个软链接就好了
ln -s /usr/local/lib/libz.so.1 /lib64/libz.so.1
