记录一个ik分词器安装bug

以后就专门准备一个bug分类来记录遇到的bug

安装ik分词器的时候, 明明已经安装成功了, 但是却没有生效

那么来一步步的排查问题

docker exec -it elasticsearch /bin/bash进入容器内部

cd /bin进入bin目录

elasticsearch-plugin list显示插件列表

这个时候发现突然就报错了

java.lang.IllegalStateException: Could not load plugin descriptor for plugin directory [elasticsearch-analysis-ik-7.6.2]

大概意思就是缺少了这个plugin-descriptor.properties文件 , 我tm从官网下载的文件还能不保真???

搞了半天. , 反反复复重新创建了很多个容器, 还有修改文件权限(chmod -R 777 /elasticsearch, 我都777了总不可能是文件权限的问题了吧)

然后反手就是一个docker restart elasticsearch , 这个时候明明也是跟正常的启动时一样的, (控制台显示containername)

这不是启动成功了吗 ??

然后docker ps 发现找不到容器

???再来!

我反手就是熟练的敲出 docker ps -a docker ps docker start elasticsearch

结果不出所料, 还是不管用. 然后我灵机一动 docker logs elasticsearch查看日志

发现还是之前的那个报错 , 这个时候就感觉到有点不对劲了, 我官网下载的代码还真能是假的???

然后我在win上面打开了下载的压缩包

。。。。。

然后我又对比了一下zip格式的压缩包

倒腾了半天原来是下载错压缩包了 , 不得不说真的很难绷得住

由于已经下载好了两个压缩包 , 但是我又突然想不起来zip 的解压命令了 , 这个时候耍了个小聪明吧zip在win解压然后又压缩成tar格式

然后反手就是一个熟练的tar -zxvf elasticsearch-analysis-ik-7.6.2.tar

结果他叕叕叕叕出问题了

[root@192 plugins]# tar -zxvf elasticsearch-analysis-ik-7.6.2.tar 

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

果然是祸不单行 , 然后在Stack Overflow上面找到了类似的问题

linux - gzip: stdin: not in gzip format tar: Child returned status 1 tar: Error is not recoverable: exiting now - Stack Overflow

这意味着该文件实际上不是一个gzip tar文件——或者任何类型的gzip文件——尽管命名类似于一个。

大概就是我在win里面压缩的tar格式的压缩包, 知识后缀相同, 实际上不是linux里面的tar格式的压缩包

那还是乖乖的用zip来解压吧

(顺便复习一下unzip命令 )

注意不能直接unzip elasticsearch-analysis-ik-7.6.2.zip

因为这样会会提取 zip 文件中所有的内容到现在的文件夹, 也就是这样。。。。

真的是一点点的踩坑啊有木有

正确的做法是 unzip -d

也就是 unzip elasticsearch-analysis-ik-7.6.2.zip -d elasticsearch-analysis-ik-7.6.2

接着启动docker start elasticsearch

[root@192 plugins]# docker ps
CONTAINER ID   IMAGE                 COMMAND                  CREATED              STATUS          PORTS                                                                                  NAMES

[root@192 plugins]#

然后我们进入容器内部docker exec -it elasticsearch /bin/bash

接着查看分词器是否安装成功

可以看到已经成功安装上了ik分词器

贴一个docker run elasticsearch

docker run --name elasticsearch -p 9200:9200 -p 9300:9300 \
-e  "discovery.type=single-node" \
-e ES_JAVA_OPTS="-Xms64m -Xmx512m" \
-v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
-v /mydata/elasticsearch/data:/usr/share/elasticsearch/data \
-v  /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
-d elasticsearch:7.6.2

再贴一个完整的安装过程

快速方法

打开官网地址 , 找到对应版本的压缩包
直接下载.zip文件
进入与docker容器挂载的目录
将下载的压缩包传输的虚拟机中
unzip ****.zip -d ****解压
- ****代表文件的名称
chmod -R ** 改变文件的执行权限

接着我们可以进入到容器内部再次确认是否安装成功

[root@192 plugins]# docker exec -it elasticsearch /bin/bash
[root@2845cb5b4e57 elasticsearch]# cd bin
[root@2845cb5b4e57 bin]# elasticsearch-plugin list
elasticsearch-analysis-ik-7.6.2
[root@2845cb5b4e57 bin]# exit    
exit
[root@192 plugins]# docker exec -it elasticsearch /bin/bash
