Rancher添加集群及部署常见应用

xw大约 6 分钟运维其他

添加Agent

创建项目集群

进入到选择集群的类型，这里选择自定义就可以

进入到添加集群-Custom页面

点击下一步

添加Linux主机节点

需要安装Docker,命令如下

  # 1.先安装yml
  yum install -y yum-utils device-mapper-persistent-data lvm2
  
  # 2.设置阿里云镜像
  sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
  
  #3. 安装docker
  yum -y install docker-ce-20.10.10-3.el7
  
  #4. 查看docker版本
  docker -v
  
  #5. 启动docker
  systemctl start docker
  
  #6. 查看docker 启动状态
  systemctl status docker

终端中运行复制下来的命令
稍等一会儿，可查看添加的集群状态

常见应用部署

Mysql

镜像：mysql:8.0
环境变量：
MYSQL_ROOT_PASSWORD=123456

路径映射
/home/data/mysql/data
/var/lib/mysql:rw
/etc/localtime
/etc/localtime:ro

在创建 Docker 容器时，加上 “-v /etc/localtime:/etc/localtime:ro” 参数
让容器使用宿主机的时间，容器时间与宿主机时间同步,:ro 指定该 volume 为只读

Nacos

镜像：nacos/nacos-server:2.0.2
端口：8848：8848

环境变量：
JVM_XMN=128m
JVM_XMS=128m
JVM_XMX=128m
MODE=standalone
MYSQL_SERVICE_DB_NAME=nacos_config
MYSQL_SERVICE_DB_PARAM=characterEncoding=utf8&connectTimeout=10000&socketTimeout=30000&autoReconnect=true&useSSL=false
MYSQL_SERVICE_HOST=112.74.107.230
MYSQL_SERVICE_PASSWORD=xdclass.net168
MYSQL_SERVICE_PORT=3306
MYSQL_SERVICE_USER=root
NACOS_AUTH_ENABLE=true
SPRING_DATASOURCE_PLATFORM=mysql

挂载目录：
宿主机：/home/data/nacos/logs  容器：/home/nacos/logs

-Xms:初始堆大小
-Xmx:最大堆大小
-Xmn:新生代大小

xxl-job

镜像：xuxueli/xxl-job-admin:2.2.0
端口：8080：8080
环境变量：
PARAMS=--spring.datasource.url=jdbc:mysql://118.195.246.204:30006/xxl_job?Unicode=true&characterEncoding=UTF-8&autoReconnect=true&serverTimezone=Asia/Shanghai \
--spring.datasource.username=root \
--spring.datasource.password=123456 \
--xxl.job.accessToken=xdclass.net

Redis

镜像：redis:6.2.4
端口：6379：6379

数据卷：
/mydata/redis/data
/data

入口命令
redis-server --requirepass 123456

ClickHouse

镜像：clickhouse/clickhouse-server:22.1.4.30
端口：8123:8123 9000:9000 9009:9009

## 环境变量
nofile=262144
privileged=true
ulimit=262144


1.log卷
clickhouse-log
/mydata/docker/clickhouse/log
/var/log/clickhouse-server

2.data卷
clickhouse-data
/mydata/docker/clickhouse/data
/var/lib/clickhouse

Zookeeper

镜像：wurstmeister/zookeeper
端口：2181：2181

Kafka

镜像：wurstmeister/kafka:2.13-2.7.0
端口：9092：9092

环境变量：
KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://120.25.217.15:9092
KAFKA_BROKER_ID=0
KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092
KAFKA_ZOOKEEPER_CONNECT=172.31.101.8:2181
KAFKA_PORT=9092

ElasticSearch7.x

在rancher主界面->资源->映射配置

elasticsearch.yml

cluster.name: "docker-cluster"
network.host: 0.0.0.0
## 开启认证
xpack.security.enabled: true
xpack.license.self_generated.type: basic
xpack.security.transport.ssl.enabled: true

* 重新配置文件，默认为空，需要重新配置

  ![](./img/20220905152330.png)

* 配置主机调度

  * 并到主机下的mydata给es文件夹添加777权限

  ```
  chmod 777 -R /mydata/es
  ```

* 配置账号密码

  * 命令行进入

  ```shell
  bin/elasticsearch-setup-passwords interactive
  ```

  * 按回车输入y，回车一直输入密码elastic即可
