 2.解決方案

升級zlib動態庫

 3.解決步驟

1.查看當前動態庫版本
strings /lib64/libz.so.1 |grep "ZLIB*"
ZLIB_1.2.0
ZLIB_1.2.0.2
ZLIB_1.2.0.8
ZLIB_1.2.2
ZLIB_1.2.2.3
ZLIB_1.2.2.4
ZLIB_1.2.3.3
ZLIB_1.2.3.4
ZLIB_1.2.3.5
ZLIB_1.2.5.1
ZLIB_1.2.5.2
發現最高版本只有1.2.5，沒有1.2.9的。

2.下載對應的zlib包並編譯
wget http://www.zlib.net/fossils/zlib-1.2.9.tar.gz  
tar xf zlib-1.2.9.tar.gz
cd zlib-1.2.9/
./configure
make && make install

3.創建新的鏈接
cp libz.so.1.2.9 /usr/lib64/
cd /usr/lib64/
rm -f libz.so.1
ln -s  libz.so.1.2.9 libz.so.1

4.確認新版本是否存在
strings /lib64/libz.so.1 |grep "ZLIB*"
