netty - jar netty-tcnative-openssl-static 似乎动态链接到机器上的 OpenSsl 库，这是正确的吗？

问题描述

我已经从源代码构建了工件 netty-tcnative-openssl-static-2.0.20.Final-linux-x86_64.jar。但是我注意到 libnetty_tcnative.so 是动态链接到 openssl 而不是静态链接：

    [root@omega 2018-12-14--00-24-20 sb are you NRUSSEL? #]ldd META-INF/native/libnetty_tcnative.so

    libselinux.so.1 => /lib64/libselinux.so.1 (0x00007febf611b000)

这是正确的还是我的构建过程有问题？

解决方案

是的，不知道你在做什么，但我只是用 netty-tcnative 的当前主分支尝试过它，它就可以工作：

./mvnw -pl openssl-static clean package

完成此操作后，您可以看到一切都符合预期：

[root@d7724df14184 code]# ldd openssl-static/target/native-lib-only/META-INF/native/linux64/libnetty_tcnative.so
ldd: warning: you do not have execution permission for `openssl-static/target/native-lib-only/META-INF/native/linux64/libnetty_tcnative.so'
    linux-vdso.so.1 =>  (0x00007ffcbadb5000)
    librt.so.1 => /lib64/librt.so.1 (0x00007faccd3b1000)
    libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00007faccd17a000)
    libpthread.so.0 => /lib64/libpthread.so.0 (0x00007facccf5d000)
    libdl.so.2 => /lib64/libdl.so.2 (0x00007facccd59000)
    libc.so.6 => /lib64/libc.so.6 (0x00007faccc9c5000)
    /lib64/ld-linux-x86-64.so.2 (0x00007faccdae9000)
    libfreebl3.so => /lib64/libfreebl3.so (0x00007faccc7c2000)

例如，您可以使用 centos 的 docker-compose 文件来确保您拥有正确的 env 环境设置：

netty-tcnative git:(master) docker-compose -f docker/docker-compose.centos.yaml -f docker/docker-compose.centos-6.18.yaml run shell
