基于docker-compose搭建 Skywalking

调整系统参数

$ vi /etc/sysctl.conf
# 调整参数
vm.max_map_count=262144
# 刷新参数

sysctl -p

编辑写docker-compose.yml文件

docker-compose.yml文件

创建用于持久化的目录

mkdir -p /docker/elasticsearch

先预先启动elasticsearch，并从elasticsearch容器中拷贝数出来的主机目录，用于持久化

# 不用挂载任何目录，快速启动es
docker run -d --name=es7 \
-p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" elasticsearch:7.5.1

# 重容器中，拷贝数据出来
mkdir -p /data/elasticsearch
docker cp es7:/usr/share/elasticsearch/data /docker/elasticsearch/
docker cp es7:/usr/share/elasticsearch/logs /docker/elasticsearch/
docker rm -f es7

开始启动 elasticsearch、oap、ui

$ docker-compose up -d

# 查看启动情况
