- 设置chrony服务器
ocp：
sh -c 'echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6'
# local clock
server 127.127.1.0
fudge 127.127.1.0 stratum 10
启动时钟服务器 Systemctl start chronyc
更新最新时钟 chronyc sources
- 建立用户，挂载文件系统（略）
- 修改limits限制、内核参数、关闭防火墙
- 网卡配置
cd /etc/sysconfig/network-scripts
cat ifcfg-enp1s0
- 配置ssh免密
ocp-ob-obp-odc-antman_20220506_arm/common/ssh/
vi address.txt 编辑IP、用户名、密码、hostname
./step1_init.sh
./step2_testlogin.sh
./step3_sethostname.sh
./step4_obssh.sh
- 下载对应版本 t-oceanbase-antman和oceanbase-all-in-one
-
-
- 安装ocp
-
-
1、安装t-oceanbase-antman
2、创建admin用户
/root/t-oceanbase-antman/clonescripts/clone.sh -u
3、配置内核参数（/etc/sysctl.conf）
/root/t-oceanbase-antman/clonescripts/clone.sh -c -r ocp
4、安装依赖包
/root/t-oceanbase-antman/clonescripts/clone.sh -m -r ocp
5、安装docker
/root/t-oceanbase-antman/clonescripts/clone.sh -i
6、上传docker镜像
docker load -i ocp323.arm.tar.gz
7、配置obcluster.conf文件
/root/t-oceanbase-antman/init_obcluster_conf.sh 选1
8、安装部署前预检查
/root/t-oceanbase-antman/clonescripts/precheck.sh -m ocp
9、安装
sh install.sh -i 1-8
