Apache Cassandra 3.11.2 无法启动 Centos 7

我试图在 Centos 7 上启动 Apache Cassandra 3.11.2，但出现错误异常：

我该如何解决 ？

    考虑升级到 3.11.14。Apache Cassandra 3.11.2 已经快 5 岁了，我很确定 JNA 库包含在其中。这本身可能会解决这个问题。

    否则，您应该能够清除/tmp/jna*文件并重新启动。

    也可能是 Cassandra 用户对目录没有足够的权限/tmp，因此您可以尝试通过将此行添加到 cassandra-env.sh 文件的末尾来重定向它。

    JVM_OPTS="$JVM_OPTS -Djava.io.tmpdir=$CASSANDRA_HOME/tmp"

  2. 发生这种UnsatisfiedLinkError情况是因为 Cassandra 没有执行/tmp目录中共享库的权限（使用noexec选项安装）。

    作为解决方法，您可以通过在 Cassandra 的文件中添加以下行来映射 JNA 临时目录conf/jvm.options：

    -Djna.tmpdir=/path/to/jna/tmp_directory

    请注意，Cassandra 进程必须对该目录具有读、写和执行权限。干杯!
