Ranger Admin安装MySQL初始化问题解决

个人博客地址：Ranger Admin安装MySQL初始化问题解决 | 一张假钞的真实世界

告警信息及如何解决见我的另外一篇博客：MySQL JDBC连接异常：javax.net.ssl.SSLException: closing inbound before receiving peer’s close_notify

但是Ranger的安装配置install.properties中未启用ssl，配置信息如下：

#SSL config
db_ssl_enabled=false
db_ssl_required=false
db_ssl_verifyServerCertificate=false
#db_ssl_auth_type=1-way|2-way, where 1-way represents standard one way ssl authentication and 2-way represents mutual ssl authentication
db_ssl_auth_type=2-way
javax_net_ssl_keyStore=
javax_net_ssl_keyStorePassword=
javax_net_ssl_trustStore=
javax_net_ssl_trustStorePassword=

跟踪源代码发现安装过程只处理了启用ssl的情况，但是新版本的mysql默认是需要启用ssl的。修改Ranger安装源代码（apache-ranger-1.2.0/security-admin/scripts/db_setup.py）增加下面代码中的221、222行，如下：

210    def get_jisql_cmd(self, user, password ,db_name):
211        path = RANGER_ADMIN_HOME
212        db_ssl_param=''
213        db_ssl_cert_param=''
214        if self.db_ssl_enabled == 'true':
215            db_ssl_param="?useSSL=%s&requireSSL=%s&verifyServerCertificate=%s" %(self.db_ssl_enabled,self.db_ssl_required,self.db_ssl_verifyServerCertificate)
216            if self.db_ssl_verifyServerCertificate == 'true':
217                if self.db_ssl_auth_type == '1-way':
218                    db_ssl_cert_param=" -Djavax.net.ssl.trustStore=%s -Djavax.net.ssl.trustStorePassword=%s " %(self.javax_net_ssl_trustStore,self.javax_net_ssl_trustStorePassword)
219                else:
220                    db_ssl_cert_param=" -Djavax.net.ssl.keyStore=%s -Djavax.net.ssl.keyStorePassword=%s -Djavax.net.ssl.trustStore=%s -Djavax.net.ssl.trustStorePassword=%s " %(self.javax_net_ssl_keyStore,self.javax_net_ssl_keyStorePassword,self.javax_net_ssl_trustStore,self.javax_net_ssl_trustStorePassword)
221        else:
222            db_ssl_param='?useSSL=false'
