Nacos server 配置 SSL 之后，Dubbo 服务启动失败

[doufum]

我们的目的就是对 nacos 开放的所有端口，加上 TLS/SSL 证书配置。

于是，对于 Nacos server 进行了 SSL 的配置：

1. 打开了 rpc 端口的 TLS 配置，dubbo 服务可以正常注册成功，9848 、9849端口配置 SSL 证书成功；

nacos.remote.server.rpc.tls.enableTls=true
nacos.remote.server.rpc.tls.certChainFile=file:/certs/ca/test-server-cert.pem
nacos.remote.server.rpc.tls.certPrivateKey=file:/certs/ca/test-server-key.pem

2. 在此基础上，再开启了 nacos 主端口 8848 的 SSL 配置后，dubbo 服务开始报错

server.ssl.key-alias=nacos_server
server.ssl.key-store=file:/certs/nacos/nacos_server.jks
server.ssl.key-store-type=JKS
server.ssl.key-store-password=123456

报错信息

caused by:
java. lang. RuntimeException: publish nacos metadata failed
at org.apache.dubbo.metadata.store.nacos.NacosMetadataReport.storeMetadata (NacosMetadataReport. java:194)

DubboConfig配置如下：

@Bean
@Primary
public MetadataReportConfig metadataReportConfig() {
    MetadataReportConfig metadataReportConfig = new MetadataReportConfig();
    String nacosAddr = env.getProperty(NACOS_ADDR);
    String nacosUsername = env.getProperty(NACOS_USERNAME);
    String nacosPassword = decodeCipher(env.getProperty(NACOS_CIPHER));
    String addr = "nacos://" + nacosAddr;
    metadataReportConfig.setAddress(addr);
    metadataReportConfig.setUsername(nacosUsername);
    metadataReportConfig.setPassword(nacosPassword);
    return metadataReportConfig;
}

@Bean
@Primary
public RegistryConfig registryConfig() {
    RegistryConfig registryConfig = new RegistryConfig();
    String nacosAddr = env.getProperty(NACOS_ADDR);
    String nacosUsername = env.getProperty(NACOS_USERNAME);
    String nacosPassword = decodeCipher(env.getProperty(NACOS_CIPHER));
    String cacheFile = env.getProperty(NACOS_CACHE_FILE);
    String addr = "nacos://" + nacosAddr + "?username=" + nacosUsername + "&password=" + nacosPassword;
    registryConfig.setAddress(addr);
    registryConfig.setFile(cacheFile);
    registryConfig.setCheck(false);
    registryConfig.setSimplified(true);
    registryConfig.setExtraKeys("ssl-enabled");
    registryConfig.setUsername(nacosUsername);
    registryConfig.setPassword(nacosPassword);

    return registryConfig;
}

@Bean
public SslConfig sslConfig() {
    SslConfig sslConfig = new SslConfig();
    // 是否开启ssl，false为不开启
    if (!BooleanUtil.toBoolean(env.getProperty(SSL_ENABLE))) {
        return sslConfig;
    }

    // 信任证书
    String collectionCert = env.getProperty(SSL_CERT_COLLECTION);
    // 证书
    String cert = env.getProperty(SSL_CERT);
    // 私钥
    String priKey = env.getProperty(SSL_KEY);
    // 私钥密码
    String password = env.getProperty(SSL_CERT_CIPHER);
    if(!StrUtil.isEmpty(password)){
        if(isEncrypted(password)){
            password=decrypt(password);
        }
    }

    // server
    // 服务端信任证书
    sslConfig.setServerTrustCertCollectionPath(collectionCert);
    // 服务端证书
    sslConfig.setServerKeyCertChainPath(cert);
    // 服务端私钥
    sslConfig.setServerPrivateKeyPath(priKey);

    // consumer
    // 客户端信任证书
    sslConfig.setClientTrustCertCollectionPath(collectionCert);
    // 客户端证书
    sslConfig.setClientKeyCertChainPath(cert);
    // 客户端私钥
    sslConfig.setClientPrivateKeyPath(priKey);

    if (StrUtil.isNotEmpty(password)) {
        // 服务端私钥密码
        sslConfig.setServerKeyPassword(password);
        // 客户端私钥密码
        sslConfig.setClientKeyPassword(password);
    }

    // 支持协议TLSv1.2
    sslConfig.setProtocols(PROTOCOLS);

    // 支持密码格式
    sslConfig.setCiphers(CIPHERS);

    return sslConfig;
}

看了一下 nacos 里面的日志，有错误的日志有：

请问一下，这个问题可以怎么排查？
