6.2. 在 Karaf 上升级 Fuse Standalone

先决条件

• 在升级前，确保您已在 Apache Karaf 安装上进行 Fuse 的完整备份。
• 启动容器（如果尚未运行）。

• 通过调用 patch:add 命令将升级安装程序文件添加到容器环境中。例如，要添加 fuse-karaf-7.9.0.fuse-790071-redhat-00001.zip 升级安装程序文件：

  patch:add file:///path/to/fuse-karaf-7.9.0.fuse-790071-redhat-00001.zip

  注意

  patch:find 命令只能用于查找和添加容器环境的最新热修复补丁 ; 它不能被应用完整的升级补丁。

  流程

  1. 运行 patch:update 命令。不需要重启容器。

     karaf@root()> patch:update
     Current patch mechanism version: 7.1.0.fuse-710023-redhat-00001
     New patch mechanism version detected: 7.2.0.fuse-720035-redhat-00001
     Uninstalling patch features in version 7.1.0.fuse-710023-redhat-00001
     Installing patch features in version 7.2.0.fuse-720035-redhat-00001

  2. 调用 patch:list 命令来显示升级安装程序列表。在此列表中，[name] 标题下的条目是升级 ID。例如：

     karaf@root()> patch:list
     [name]                                    [installed] [rollup] [description]
     fuse-karaf-7.2.0.fuse-720035-redhat-00001 false       true     fuse-karaf-7.2.0.fuse-720035-redhat-00001

  3. 通过调用 patch:simulate 命令并为您要应用的升级指定升级 ID 来模拟升级，如下所示：

     karaf@root()> patch:simulate fuse-karaf-7.2.0.fuse-720035-redhat-00001
     INFO : org.jboss.fuse.modules.patch.patch-management (226): Installing rollup patch "fuse-karaf-7.2.0.fuse-720035-redhat-00001"

     aries-blueprint                4.2.0.fuse-710024-redhat-00002    4.2.0.fuse-720061-redhat-00001

     com.fasterxml.jackson.core.jackson-annotations                 2.8.11                            mvn:com.fasterxml.jackson.core/jackson-annotations/2.8.11
     ...
     Simulation only - no files and runtime data will be modified.
     karaf@root()>

     这会生成执行升级时将对容器进行的更改日志，但不会对容器进行任何更改。检查模拟日志，以了解要对容器进行的更改。

  4. 通过调用 patch:install 命令并为您要应用的升级指定升级 ID 来升级容器。例如：

     karaf@root()> patch:install fuse-karaf-7.9.0.fuse-790071-redhat-00001

  5. 通过搜索其中一个升级工件来验证升级。例如，如果您刚刚将 Fuse 7.1.0 升级到 Fuse 7.2.0，您可以搜索构建号 790071 的捆绑包，如下所示：

     karaf@root()> bundle:list -l | grep 790071
      22 │ Active │  80 │ 7.9.0.fuse-790071-redhat-00001  │ mvn:org.jboss.fuse.modules/fuse-pax-transx-tm-narayana/7.9.0.fuse-790071-redhat-00001
     188 │ Active │  80 │ 7.9.0.fuse-790071-redhat-00001  │ mvn:org.jboss.fuse.modules.patch/patch-commands/7.9.0.fuse-790071-redhat-00001
