基于docker-compose部署skywalking

前提

安装好docker和docker-compose

修改系统参数

$ vi /etc/sysctl.conf
vm.max_map_count=262144
$ sysctl -p

$ vi/etc/systemd/system.conf
DefaultLimitNOFILE=65536
DefaultLimitNPROC=32000
DefaultLimitMEMLOCK=infinity
$ systemctl daemon-reload

$ vi /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc 4096
* hard nproc 4096
* hard memlock unlimited
* soft memlock unlimited

创建目录

$ mkdir -p /data/elasticsearch/data
$ chmod -R 777 /data/elasticsearch/data
$ cd /data/elasticsearch/

编写docker-compose.yml文件

version: '3.3'
services:
  es7:
    image: elasticsearch:7.10.1
    container_name: es7
    ports:
      - 9200:9200
      - 9300:9300
    environment:
      - discovery.type=single-node #单例模式
      - bootstrap.memory_lock=true #锁定物理内存地址，防止es内存被交换出去，也就是避免es使用swap交换分区，频繁的交换，会导致IOPS变高
      - "ES_JAVA_OPTS=-Xms1048m -Xmx1048m" #堆内存大小
      - TZ=Asia/Shanghai
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - /data/elasticsearch/data:/usr/share/elasticsearch/data

  skywalking-oap:
    image: apache/skywalking-oap-server:8.3.0-es7
    container_name: skywalking-oap
    restart: always
    depends_on:
      - es7
    links:
      - es7
    ports:
      - 11800:11800
      - 12800:12800
    environment:
      TZ: Asia/Shanghai
      SW_STORAGE: elasticsearch7
      SW_STORAGE_ES_CLUSTER_NODES: es7:9200

  skywalking-ui:
    image: apache/skywalking-ui:8.3.0
    container_name: skywalking-ui
    restart: always
    depends_on:
      - skywalking-oap
    links:
      - skywalking-oap
    ports:
      - 8080:8080
    environment:
      TZ: Asia/Shanghai
      SW_OAP_ADDRESS: skywalking-oap:12800

启动

docker-compose up -d
