参照《深入理解Java虚拟机第三版》1.6节与[https://github.com/AdoptOpenJDK/openjdk-jdk12u/blob/master/doc/building.md][https_github.com_AdoptOpenJDK_openjdk-jdk12u_blob_master_doc_building.md]，步骤如下：

获取openjdk12的源码，书中给出的地址实在是太慢了，我在github上找了个[镜像][Link 1]，点击下载，获得zip压缩包，解压缩。

sudo yum install java-11-openjdk*

chmod +x configure
    sudo ./configure --enable-debug --with-jvm-variants=server

注意此步可能因缺少依赖而报失败，根据提示安装即可，我先后进行下列安装后此步成功了：

sudo yum install autoconf
    sudo yum install libXtst-devel libXt-devel libXrender-devel libXrandr-devel libXi-devel
    sudo yum install cups-devel
    sudo yum install alsa-lib-devel

我得到的成功提示：

====================================================
    A new configuration has been successfully created in
    /root/openjdk12/build/linux-x86_64-server-fastdebug
    using configure arguments '--enable-debug --with-jvm-variants=server'.
    
    Configuration summary:
    * Debug level:    fastdebug
    * HS debug level: fastdebug
    * JVM variants:   server
    * JVM features:   server: 'aot cds cmsgc compiler1 compiler2 dtrace epsilongc g1gc graal jfr jni-check jvmci jvmti management nmt parallelgc serialgc services shenandoahgc vm-structs zgc' 
    * OpenJDK target: OS: linux, CPU architecture: x86, address length: 64
    * Version string: 12.0.2-internal+0-adhoc.root.openjdk12 (12.0.2-internal)
    
    Tools summary:
    * Boot JDK:       openjdk version "11.0.10" 2021-01-19 LTS OpenJDK Runtime Environment 18.9 (build 11.0.10+9-LTS) OpenJDK 64-Bit Server VM 18.9 (build 11.0.10+9-LTS, mixed mode, sharing)  (at /usr/lib/jvm/java-11-openjdk-11.0.10.0.9-0.el7_9.x86_64)

    Build performance summary:
    * Cores to use:   1
    * Memory limit:   1819 MB

然后`make images`，要运行一段时间

Verify the newly built JDK: `./build/*/images/jdk/bin/java -version`

Run basic tests: `make run-test-tier1`
