SonarQube升级

1.阅读SonarQube更新日志：

http://docs.codehaus.org/display/SONAR/Upgrading#Upgrading-ReleaseUpgradeNotes

2.停止SonarQube服务：

bin/<SYSTEM>/sonar stop

3.下载新版本号的SonarQube及SonarQube Runner，并解压至新的文件夹NEW_SONARQUBE_HOME

http://www.sonarqube.org/downloads/

4.更新NEW_SONARQUBE_HOME/conf下sonar.properties与wrapper.conf文件中的内容，文件内容參照OLD_SONARQUBE_HOME/conf下对应配置文件的内容，但切记千万不要直接将原来的配置文件拷贝覆盖，由于新的sonar.properties与wrapper.conf文件还包括新版本号的一些配置项。

5.拷贝OLD_SONARQUBE_HOME/extensions/plugins中的插件至NEW_SONARQUBE_HOME/extensions/plugins

6.假设使用的是自己定义的JDBC驱动。将其拷贝至NEW_SONARQUBE_HOME/extensions/jdbc-driver/<dialect>

7.备份数据库：MySQL:

/usr/local/mysql# mysqldump -u sonar -p sonar>sonar.sql

8.启动SonarQube:

bin/<SYSTEM>/sonar stop

9.用浏览器訪问http://localhost:9000/setup （注意：不再是直接訪问localhost:9000），依据提示升级

10.依据实际情况改动系统中或持续集成中全部涉及SONAR_HOME和SONAR_RUNNER_HOME环境变量

11.使用新版SonarQube Runner分析项目

可能遇到的问题：

一、分析项目时报插件兼容性错误

解决：登录http://localhost:9000 WEB中配置——更新中心，将plugins都更新至最新版本号

注：更新Java Plugin时将会有个警告。

• Version 2.4 moves Java from being an "ecosystem" of multiple plugins to a single, stand-along plugin that encompasses most of the functionality formerly contained in the ecosystem. Unfortunately, SonarQube's update center cannot
  handle the switch gracefully. You may use the update center to download the new version of the plugin. However,you must manually remove the Surefire, JaCoCo, and Squid for Java plugins from $SONARQUBE_HOME/extensions/plugins.

因此。在更新中心中下载新版本号Java Plugin后，须要将$SONARQUBE_HOME/extensions/plugins下老的Surefire,
JaCoCo, and Squid插件jar包删除，并重新启动服务

二、Impossible to upgrade database

Migration failed: An error has occurred, all later migrations canceled: ActiveRecord::JDBCError: Specified key was too long; max key length is 1000 bytes: CREATE UNIQUE INDEX `rules_repo_key`
ON `rules` (`plugin_name`, `plugin_rule_key`) .

Please check logs.

原因：Sonar在MySQL中对表建立索引时。key的长度超过1000 bytes了。因为MySQL使用MyISAM engine时会有key长度的限制。若MySQL使用的是MyISAM engine的话将会出现这个问题

解决：将MySQL的默认engine改动为INNODB

1.检查当前的引擎 

mysql> show engines; 

2.确认确实使用的是MyISAM后，将默认engine改动为INNODB。并重新启动MySQL服务

改动my.cnf配置文件：

/etc/mysql/my.cnf

default-storage-engine=INNODB
# Uncomment the following if you are using InnoDB tables
innodb_data_home_dir = /usr/local/var
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = /usr/local/var
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
innodb_buffer_pool_size = 256M
innodb_additional_mem_pool_size = 20M
# Set .._log_file_size to 25 % of buffer pool size
innodb_log_file_size = 64M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50

3.查看是否支持动态载入

mysql>show variables like "have_%";

查看have_dynamic_loading这行，假设是YES。则继续 

4.安装插件

mysql>INSTALL PLUGIN INNODB SONAME 'ha_innodb_plugin.so';
mysql>INSTALL PLUGIN INNODB_TRX SONAME 'ha_innodb_plugin.so';
mysql>INSTALL PLUGIN INNODB_LOCKS SONAME 'ha_innodb_plugin.so';
mysql>INSTALL PLUGIN INNODB_LOCK_WAITS SONAME 'ha_innodb_plugin.so';
mysql>INSTALL PLUGIN INNODB_CMP SONAME 'ha_innodb_plugin.so';
mysql>INSTALL PLUGIN INNODB_CMP_RESET SONAME 'ha_innodb_plugin.so';
mysql>INSTALL PLUGIN INNODB_CMPMEM SONAME 'ha_innodb_plugin.so';
mysql>INSTALL PLUGIN INNODB_CMPMEM_RESET SONAME 'ha_innodb_plugin.so' 

5.再次查看当前的引擎

mysql> show engines;

6.查看sonar库中有哪些表是使用的MyISAM engine（注：这里TABLE_SCHEMA中的‘sonar’为安装sonar建库时数据库的名称，需改成自身建库时的名称）

SELECT TABLE_NAME, ENGINE   FROM information_schema.TABLES   WHERE TABLE_SCHEMA = 'sonar';

7.将对应的表更新为INNODB

ALTER TABLE sonar.widgets ENGINE=INNODB;
ALTER TABLE sonar.user_roles ENGINE=INNODB;
ALTER TABLE sonar.users ENGINE=INNODB;
ALTER TABLE sonar.snapshot_sources ENGINE=INNODB;

三、服务端分析项目时或Eclipse本地分析时报

Caused by: org.sonar.api.utils.SonarException: The plugin findbugs
is not supported with Java 1.6.0_**

因为最新版本号的findbugs插件须要JDK1.7及以上的支持，因此须要安装JDK1.7以上

对于Eclipse。若不想改变系统的JAVA环境，而仅仅改变Eclipse中的JAVA环境，则可在eclipse.ini文件里添加

-vm

%JAVA1.7_HOME%/bin/javaw.exe
