docker-compose部署SkyWalking

1.基本環境

操作系統

# cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)


# uname -srm
Linux 3.10.0-693.el7.x86_64 x86_64

依賴環境

# docker -v
Docker version 20.10.10, build b485636

# docker-compose -v
docker-compose version 1.29.2, build 5becea4c

2.系統參數調整

sysctl.conf 參數調整

#vi /etc/sysctl.conf
##開啓內核轉發
net.ipv4.ip_forward = 1
##ES參數
vm.max_map_count=262144

# sysctl -p

system.conf 參數調整

# vi /etc/systemd/system.conf
DefaultLimitNOFILE=65536
DefaultLimitNPROC=32000
DefaultLimitMEMLOCK=infinity

# systemctl daemon-reexec

limits.conf 參數調整

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

3.文件準備

說明：操作目錄位置 /data/sdv1/SkyWalking 全局變量文件準備

# cd /data/sdv1/SkyWalking
# cat .env
ES_VERSION=7.4.2
OAP_IMAGE=172.27.18.160/library/apache/skywalking-oap-server:8.7.0-es7
UI_IMAGE=172.27.18.160/library/apache/skywalking-ui:8.7.0

docker-compose.yml 文件準備

# cd /data/sdv1/SkyWalking
# cat docker-compose.yml
version: '3.8'

驗證變量是否獲取成功

# docker-compose config

鏡像 pull

# docker-compose pull

4.服務啓動及驗證

啓動服務

# docker-compose up -d

訪問驗證（elasticsearch）

# curl http://$IP:9200/
