环境
- idea 2022.1.3
- jdk17
- macos 10.14.6
- gradle 7.4.2(代码自动下载)
前置准备
idea设置JDK17idea设置gradle JVM为Project JVMgradle设置aliyun加速（可选）,有时设置了不如不设置更好
开始导入
- 导入项目 使用
ideaopen项目下的build.gradle，等待编译结束 - 编译
8.1版本的发行包 这一步会下载所需的依赖jdk，如果报错可以多尝试几次，或者切换网络，执行该命令时， 注意终端jdk环境
./gradlew localDistro
- 复制发行包到项目根目录同级目录新建
home文件夹下，文件结构如下

- 启动 找到
Elasticsearch.java运行main方法 - 报错1：
ERROR: the system property [es.path.conf] must be set
-Des.path.conf=/cxt/codework/github/elasticsearch/8.1/home/config
- 报错2：
path.home is not configured
-Des.path.home=/cxt/codework/github/elasticsearch/8.1/home
- 报错3：
main ERROR Could not register mbeans java.security.AccessControlException: access denied ("javax.management.MBeanTrustPermission" "register") - 创建一个
java.policy,内容如下(完整内容在末尾获取)
grant { permission javax.management.MBeanTrustPermission "register"; };
运行时指定
-Djava.security.policy=/cxt/codework/github/elasticsearch/8.1/home/config/java.policy
- 报错4：
access denied ("java.lang.RuntimePermission" "createClassLoader")刚才的java.policy文件中增加如下(完整内容在末尾获取)
permission java.lang.RuntimePermission "createClassLoader";
- 报错5：
java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "setContextClassLoader")刚才的java.policy文件中增加如下(完整内容在末尾获取)
permission java.lang.RuntimePermission "setContextClassLoader";
- 报错6：
access denied ("org.elasticsearch.secure_sm.ThreadPermission" "modifyArbitraryThreadGroup")刚才的java.policy文件中增加如下(完整内容在末尾获取)
permission org.elasticsearch.secure_sm.ThreadPermission "modifyArbitraryThreadGroup";
- 报错7：报错如下(完整内容在末尾获取)
Caused by: java.lang.IllegalArgumentException: Unknown codebases [codebase.elasticsearch-plugin-classloader, codebase.elasticsearch, codebase.elasticsearch-secure-sm] in policy file [file:/cxt/codework/github/elasticsearch/8.1/elasticsearch/server/out/production/resources/org/elasticsearch/bootstrap/security.policy]
解决如下，找到 server/src/main/resources/org/elasticsearch/bootstrap/security.policy，注释掉一下三个 [codebase.elasticsearch-plugin-classloader, codebase.elasticsearch, codebase.elasticsearch-secure-sm]
//grant codeBase "${codebase.elasticsearch-plugin-classloader}" { // needed to create the classloader which allows plugins to extend other plugins //permission java.lang.RuntimePermission "createClassLoader"; //}; //grant codeBase "${codebase.elasticsearch-secure-sm}" { // permission java.security.AllPermission; //}; Elasticsearch core: These are only allowed inside the server jar, not in plugins //grant codeBase "${codebase.elasticsearch}" { // needed for loading plugins which may expect the context class loader to be set // permission java.lang.RuntimePermission "setContextClassLoader"; //};
总结
- 完整的启动参数设置如下
-Des.path.conf=/cxt/codework/github/elasticsearch/8.1/home/config -Des.path.home=/cxt/codework/github/elasticsearch/8.1/home -Djava.security.policy=/cxt/codework/github/elasticsearch/8.1/home/config/java.policy -Dlog4j2.disable.jmx=true
也可以在Elasticsearch.main方法执行前通过代码的形式指定环境变量(可选)
System.setProperty("es.path.conf","/cxt/codework/github/elasticsearch/8.1/home/config"); System.setProperty("es.path.home", "/cxt/codework/github/elasticsearch/8.1/home"); System.setProperty("log4j2.disable.jmx", "true"); System.setProperty("java.security.policy","/cxt/codework/github/elasticsearch/8.1/home/config/java.policy");
- 完整的
java.policy文件如下
grant { permission javax.management.MBeanTrustPermission "register"; permission java.lang.RuntimePermission "createClassLoader"; permission java.lang.RuntimePermission "setContextClassLoader"; permission org.elasticsearch.secure_sm.ThreadPermission "modifyArbitraryThreadGroup"; };
