# nextcloud16 es7.3 全文检索 #

## nextcloud 安装3个app 插件 ##

Full text search  
Full text search - Elasticsearch Platform  
Full text search - Files

## 设置插件 ##

设置->全文检索->Servelet地址:[http://localhost:9200/][http_localhost_9200]  
设置->全文检索->\[高级\] 分析器tokenizer: ik\_smart

## 安装ES插件 ##

# ingest-attachment
    /usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-attachment
    
    #安装IK分词
    /usr/share/elasticsearch/bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.3.0/elasticsearch-analysis-ik-7.3.0.zip

## 初始化索引 ##

cd /var/www
    sudo -u nginx ./occ fulltextsearch:index

## 创建并启动服务 ##

由于全文索引需要不停的进行（因为有新的文件进来），做成centos服务

vi /etc/systemd/system/nextcloud-fulltext-elasticsearch-worker.service
    修改目录 user group 内容 
    
    [Unit]
    Description=Elasticsearch Worker for Nextcloud Fulltext Search
    After=network.target
    
    [Service]
    User=nginx
    Group=nginx
    WorkingDirectory=/var/www
    ExecStart=/usr/bin/php /var/www/occ fulltextsearch:live -q
    ExecStop=/usr/bin/php /var/www/occ fulltextsearch:stop
    Nice=19
    Restart=always
    
    [Install]
    WantedBy=multi-user.target

#开机启动
    systemctl enable nextcloud-fulltext-elasticsearch-worker
    systemctl start nextcloud-fulltext-elasticsearch-worker

## 问题 ##

### pipeline with id \[attachment\] does not exist ###

│ Error:      2/2
    │ Index: files:478
    │ Exception: Elasticsearch\Common\Exceptions\BadRequest400Exception
    │ Message: pipeline with id [attachment] does not exist
    
    重建索引
    cd /var/www
    sudo -u nginx ./occ fulltextsearch:reset
    sudo -u nginx ./occ fulltextsearch:index

### Search platform (Elasticsearch) down ? ###

启动ES `systemctl start elasticsearch` ，当然你需要稍微等一下他启动

### In IndexService.php line 253: please add ingest-attachment plugin to elasticsearch ###

In IndexService.php line 253:
      please add ingest-attachment plugin to elasticsearch 
    
    安装插件
    /usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-attachment

### The current PHP memory limit is below the recommended value of 512MB ###

编辑php.ini
    memory_limit = 512M

### php The posix extensions are required ###

yum install php-process -y
