docker images
查看本地镜像
docker ps
查看运行中的docker容器
docker ps -a 查看所有容器，包括退出的。
查看某镜像启动日志
docker logs 镜像id
docker search tomcat
从镜像仓库搜索镜像
pull镜像
docker pull tomcat
启动/关闭/重启容器
docker start/stop/restart 容器id
运行容器-tomcat
docker run -d -p 8080:8080 tomcat
-d: 后台启动
-p: 端口映射
-P: 随机端口映射。docker run -d -P tomcat
进入容器
docker run -d -p 8080:8080 tomcat => 启动tomcat容器后，并没有进入容器。
- docker attach 容器id => 退出后会关闭容器(不推荐)
- docker exec -it 容器id bash
-i: interactive 交互的
-t: terminal 伪终端
bash: 这个参数必须带，或者写成/bin/bash也行
退出容器
exit
删除容器
docker rm 容器id1 容器id2
如果容器运行中，可以加-f强制删除：force
docker容器中没有vi/vim等命令
apt-get update
apt-get install vim
容器重命名
docker rename 原容器名 新容器名
本地复制文件到docker容器内
docker cp xxx containerId:/usr/share/elasticsearch/plugins
docker容器内复制文件到本地
docker cp containerId:/usr/share/elasticsearch/plugins/a.txt /root
elasticsearch踩坑
给/usr/share/elasticsearch/plugins下复制了一个ik分词器文件进去，然后elasticsearch容器重启失败，而不进入容器又不能做文件删除(但可以从里边cp文件到本地)。
docker貌似不提供：在不启动容器的情况下对容器内文件的删除操作。
于是本地全局搜索：find / -name xxx => 删除文件后elasticsearch正常启动。

ik分词器
ik分词器的版本号要跟es完全一致[小版本号也要一致]
如果找不到对应版本号的ik分词器，可以修改plugin-descriptor.properties的版本号，这样能够正常启动es。
对于ik分词器建议是索引时使用ik_max_word将搜索内容进行细粒度分词，搜索时使用ik_smart提高搜索精确性
输入：
{
"analyzer": "ik_max_word", -- 最多分词数量
"text": "我是中国人"
}
输出：
{
"tokens": [
{
"token": "我",
"start_offset": 0,
"end_offset": 1,
"type": "CN_CHAR",
"position": 0
},
{
"token": "是",
"start_offset": 1,
"end_offset": 2,
"type": "CN_CHAR",
"position": 1
},
{
"token": "中国人",
"start_offset": 2,
"end_offset": 5,
"type": "CN_WORD",
"position": 2
},
{
"token": "中国",
"start_offset": 2,
"end_offset": 4,
"type": "CN_WORD",
"position": 3
},
{
"token": "国人",
"start_offset": 3,
"end_offset": 5,
"type": "CN_WORD",
"position": 4
}
]
}
======================
输入：
{
"analyzer": "ik_smart", -- 聪明的分词(比较精准，比较少)
"text": "我是中国人"
}
输出：
{
"tokens": [
{
"token": "我",
"start_offset": 0,
"end_offset": 1,
"type": "CN_CHAR",
"position": 0
},
{
"token": "是",
"start_offset": 1,
"end_offset": 2,
"type": "CN_CHAR",
"position": 1
},
{
"token": "中国人",
"start_offset": 2,
"end_offset": 5,
"type": "CN_WORD",
"position": 2
}
]
}
docker启动MySQL
docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 id
docker exec -it id bash
bash-4.2$ mysql -h 127.0.0.1 -u root
Enter password:123456
