我正在托管 RHEL8 实例上部署 Apache Cassandra。如果我在没有 noexec 标志的情况下重新挂载 /tmp，我可以成功安装并启动 Cassandra。一夜之间，公司安全策略恢复了 noexec 标志。
如果存在 noexec 标志，Cassandra 无法启动并出现错误
ERROR [main] 2024-06-24 10:19:18,156 NativeLibraryLinux.java:65 - Failed to link the C library against JNA. Native methods will be unavailable.
java.lang.UnsatisfiedLinkError: /tmp/jna8661137960014770832.tmp: /tmp/jna8661137960014770832.tmp: failed to map segment from shared object
解决方案应该是更改 Cassandra 的 tmp 目录。我在 cassandra-env.sh 中设置了以下内容：
JVM_OPTS="$JVM_OPTS -Djna.tmpdir=/var/lib/cassandra/tmp"
JVM_OPTS="$JVM_OPTS -Djava.io.tmpdir=/var/lib/cassandra/tmp"`
我在 Cassandra 启动的早期阶段遇到了另一个错误：
# A fatal error has been detected by the Java Runtime Environment:
#

# Problematic frame:

从上面可以看到，致命错误发生在jna库中。
检查错误报告文件，看起来像是链接错误：

我正在使用 Apache Cassandra 4.1.5-1 中捆绑的 jna JAR（jna JAR：jna-5.9.0.jar）。
我尝试卸载并重新安装 Cassandra 和 Java。 安装的Java版本是yum确定的依赖： java-1.8.0-openjdk-headless.x86_64 1:1.8.0.412.b08-2.el8 @rhel-8-for-x86_64-appstream-rpms
这看起来与此处描述的问题相同：https://issues.apache.org/jira/browse/CASSANDRA-19565
尝试升级到4.1.6。
