报错内容

Caused by: java.lang.UnsatisfiedLinkError: /tmp/snappy-1.1.7-4a4b576a-c34c-481e-b6ac-9b4abacb112e-libsnappyjava.so:

描述

因为项目中使用了org.xerial.snappy.Snappy这个类，在正常的centos系统环境下，没有问题；在微服务容器（openjdk:8-jdk-alpine）测试的时候发现有一个功能不正常，爬出了以上重要的日志java

发现org.xerial.snappy.Snappy这个类没法初始化，日志往上查发现了真实的状况，即java.lang.UnsatisfiedLinkError: /tmp/snappy-1.1.7-4a4b576a-c34c-481e-b6ac-9b4abacb112e-libsnappyjava.so: Error loading shared library ld-linux-x86-64.so.2: No such file or directory (needed by /tmp/snappy-1.1.7-4a4b576a-c34c-481e-b6ac-9b4abacb112e-libsnappyjava.solinux

经过这个信息能够定位出是未找到ld-linux-x86-64.so库git

解决方式

因为openjdk:8-jdk-alpine容器使用的是Alpine Linux，经多方查找，能够使用如下方式解决github

建立软链接，若是/lib目录下有linux-x86-64.so.2能够不用执行后边的操做，没有则须要继续安装
ln -s /lib /lib64web

并安装多个库
apk add --no-cache bash tini libc6-compat linux-pam krb5 krb5-libsspring

bash不是必须的，只是用起来方便apache

最后添加到Dockerfile中以下
centos
