1、关闭防火墙，或者添加白名单

systemctl status firewalld
systemctl stop firewalld
systemctl disable firewalld
iptables -L 列出防火墙规则
iptables -F 清空防火墙规则

查询指定端口是否已开: firewall-cmd --query-port=5236/tcp
添加对外开放端口 firewall-cmd --add-port=6379/tcp --permanent
防火墙添加端口
vi /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport 5236 -j ACCEPT
永久生效
查询指定端口是否开放: netstat -apn |grep 6379
service iptables save
service iptables restart
vi /etc/sysconfig/selinux 添加ip

关闭selinux，重启生效
vi /etc/selinux/config
修改 SELINUX=disabled

2、配置用户权限
vi /etc/security/limits.conf

root soft as unlimited
root hard as unlimited
root soft fsize unlimited
root hard fsize unlimited
root soft nproc 10240
root hard nproc 10240
root soft nofile 65536
root hard nofile 65536
root soft core unlimited
root hard core unlimited
root soft data unlimited
root hard data unlimited

3、操作系统分配策略overcommit_memory设置为0

vi /etc/sysctl.conf
vm.overcommit_memory=0

是配置文件生效
sysctl -p
查看是否修改成功
cat /proc/sys/vm/overcommit_memory

4、64位

getconf LONG_BIT
glibc 3以上版本
find / -name libssl.so.10
将libcrypto.so.10 和 libssl.so.10复制到/usr/lib64

5、root安装部署，默认在/opt下，指定安装到/data下

rpm -ivh cdm-V1.0-20241213.x86_64.rpm --relocate /opt=/data
或者rpm -ivh cdm-V1.0-20241213.x86_64.rpm --prefix=/data

卸载rpm -e cdm-V1.0-20241213_c8d8c6a6

6、注册服务

cd /data/dmncdb/cdm/bin/scripts
./cdm_service_installer.sh -n 6379 -p 6379
–服务路径
/usr/lib/systemd/system/CDMService6379.service
/data/dmncdb/cdm/bin/services
–启动服务
systemctl start CDMService6379.service
或者
cd /data/dmncdb/cdm/bin/services/
./CDMService6379 start

–连接数据库
cd /data/dmncdb/cdm/thirdparty
./redis-cli -p 6379

6、替换授权

达梦新云缓存数据库实例关闭
systemctlstart CDMService6380

备份授权
cd /data/dmncdb/cdm/bin
替换原有的 cdm_server.key

启动服务后，redis-cli连接到cdm_server 执行info license 命令，核对授权信息是否更新
