虚拟机上运行UBUNTU18.04系统，分配的内存16G,磁盘60G,内核8个。
#安装docker
apt-get install -y docker.io
systemctl start docker
systemctl enable docker
拉取镜像
docker pull oceanbase/oceanbase-ce
启动一个空的oceanbase实例
docker stop oceanbase
docker rm oceanbase
docker run -d --name oceanbase -p 3306:2881 -e MODE=SLIM oceanbase/oceanbase-ce
timeout 300s bash -c ‘until docker logs oceanbase 2>&1 | tail -n1 | grep -q “^boot success!$”; do sleep 1; done’ && echo “成功” || echo “超时”
启动成功后，把docker实例文件拷贝到宿主机中，这样就保证了数据库的持久化
docker cp oceanbase:/root/demo/. /home/zxjc/oceanbase/obdata
chmod -R 777 /home/zxjc/oceanbase
用指定的宿主机上的文件,来启动实例，实例启动成功
docker stop oceanbase
docker rm oceanbase
docker run -d --name oceanbase -p 3306:2881 -e MODE=SLIM -e EXIT_WHILE_ERROR=false -e TZ=Asia/Shanghai --ulimit stack=-1:-1 -v /home/zxjc/oceanbase/obdata:/root/demo -v /home/zxjc/oceanbase/jczd:/root/jczd Quay
timeout 300s bash -c ‘until docker logs oceanbase 2>&1 | tail -n1 | grep -q “^boot success!$”; do sleep 1; done’ && echo “成功” || echo “超时”
重新启动，测试其是否能正常运行
docker restart oceanbase
timeout 300s bash -c ‘until docker logs oceanbase 2>&1 | tail -n1 | grep -q “^boot success!$”; do sleep 1; done’ && echo “成功” || echo “超时”
docker logs oceanbase,输出如下错误：
