本文档提供了在安装JBoss Enterprise Application Platform (EAP) 5.0之前，如何验证系统是否已正确安装Java及C运行时环境的方法。通过在命令行中输入特定命令，用户可以检查Java是否在系统路径中，以及对于Linux环境，如何确认glibc的存在。

环境

JBoss Enterprise Application Platform (EAP) 5.0
Red Hat Enterprise Linux

问题

Documentation on the Installation Guide states "you must have a working installation of Java and a C runtime."
How do I verify that I have a working installation of Java and a C runtime prior to installation?

决议

Java

Open up a command shell and type the following to see if java is in the PATH:

Raw

java -version

C runtime

For JBoss EAP on Linux, verfiy that glibc is installed.
For other applications, Run ldd on the application

诊断步骤

Use ldd on Linux to determine shared object library dependencies. For example, the following shows glibc dependencies:

Raw


2] Run ldd on the application, say utility is 'ls' command 

ldd `which ps`
    linux-vdso.so.1 =>  (0x00007ffe97d35000)
    libprocps.so.4 => /lib64/libprocps.so.4 (0x00007ffabd8b0000)
    libsystemd-login.so.0 => /lib64/libsystemd-login.so.0 (0x00007ffabd8a3000)
    libdl.so.2 => /lib64/libdl.so.2 (0x00007ffabd69e000)
    libc.so.6 => /lib64/libc.so.6 (0x00007ffabd2db000)
    librt.so.1 => /lib64/librt.so.1 (0x00007ffabd0d3000)
    libcap.so.2 => /lib64/libcap.so.2 (0x00007ffabcecd000)
    libm.so.6 => /lib64/libm.so.6 (0x00007ffabcbcb000)
    libdw.so.1 => /lib64/libdw.so.1 (0x00007ffabc984000)
    libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007ffabc76d000)
    libpthread.so.0 => /lib64/libpthread.so.0 (0x00007ffabc551000)
    /lib64/ld-linux-x86-64.so.2 (0x00007ffabdaf2000)
    libattr.so.1 => /lib64/libattr.so.1 (0x00007ffabc34c000)
    libelf.so.1 => /lib64/libelf.so.1 (0x00007ffabc133000)
    libz.so.1 => /lib64/libz.so.1 (0x00007ffabbf1d000)
    liblzma.so.5 => /lib64/liblzma.so.5 (0x00007ffabbcf7000)
    libbz2.so.1 => /lib64/libbz2.so.1 (0x00007ffabbae6000)

3] Now you can run rpm -qf for each listed library and compile the list of required packages.

#rpm -qf /lib64/libprocps.so.4
procps-ng-3.3.10-3.el7.x86_64

#rpm -qf /lib64/libsystemd-login.so.0
systemd-libs-219-30.el7_3.9.x86_64
