2 安装部署dmncdm

（清理之前部署的环境）

2.1 196部署cdm环境

[root@localhost home]# ls
cdm-V1.0-20241213.x86_64.rpm  dmdba  mnt
[root@localhost home]# rpm -ivh cdm-V1.0-20241213.x86_64.rpm

rpm包已安装至/opt/dmncdb/cdm目录下！
[root@localhost home]#

2.2 197部署cdm环境

[root@localhost home]# ls
cdm-V1.0-20241213.x86_64.rpm  dmdba
[root@localhost home]# rpm -ivh cdm-V1.0-20241213.x86_64.rpm

3 主备集群/主从集群配置

主从配置文件修改

[root@localhost conf]# vi /opt/dmncdb/cdm/conf/hosts
[root@localhost bin]# cat /opt/dmncdb/cdm/conf/hosts
# 根据主备的部署规划信息，配置 CDM 各服务节点 IP、PORT 以及对应服务器系统中用户名和密码。

# CDM_MS 主备部署节点信息
#
# 主节点数量只有一个，部署信息为第一条 Master 的信息；
# 备节点个数不限，每添加一个服务节点的部署，都需要增加一条 "Slave" 记录。
# 其中：
# (1) IP 表示运行 CDM_MS 服务的机器 ip 地址；
# (2) PORT 表示运行 CDM_MS 服务的端口号，端口号默认使用 6379；
# (3) USER 表示运行 CDM_MS 服务的机器系统用户，非 root 用户需要部署前配置好该用户的 sudo 免密权限；
# (4) PWD 表示运行 CDM_MS 服务的机器系统用户的密码。
#
# 例如，部署 CDM_MS 的1主2备节点信息：
# Master: "ip=192.168.1.10", "port=6379", "user=root", "password=123456"
# Slave: "ip=192.168.1.20", "port=6379", "user=root", "password=123456"
# Slave: "ip=192.168.1.30", "port=6379", "user=root", "password=123456"
#
[CDM_MS]
Master: "ip=192.168.100.196", "port=6330", "user=root", "password=DAMENG@123"
Slave: "ip=192.168.100.197", "port=6330", "user=root", "password=DAMENG@123"

# CDM_Monitor 监听部署节点信息
#
# 节点个数不限（建议部署奇数个节点），每添加一个节点的部署，都需要增加一条 "Monitor" 记录，其中：
# (1) MONITOR_IP 表示运行 CDM_Monitor 服务的机器 ip 地址；
# (2) MONITOR_PORT 表示运行 CDM_Monitor 服务的端口号，端口号默认使用 26379；
# (3) MONITOR_USER 表示运行 CDM_Monitor 服务的机器系统用户，非 root 用户需要部署前配置好该用户的 sudo 免密权限；
# (4) MONITOR_PWD 表示运行 CDM_Monitor 服务的机器系统用户的密码。
#
# 例如，部署包括3个 CDM_Monitor 节点信息：
# Monitor: "ip=192.168.1.10", "port=26379", "user=root", "password=123456"
# Monitor: "ip=192.168.1.20", "port=26379", "user=root", "password=123456"
# Monitor: "ip=192.168.1.30", "port=26379", "user=root", "password=123456"
#
[CDM_Monitor]
Monitor: "ip=192.168.100.190", "port=26330", "user=root", "password=DAMENG@123"

# 其他参数
#
# 数据文件目录
#
# 请确保数据文件存放的路径有足够大的磁盘空间
# 默认为空，使用服务默认路径
# 例如：data_dir="/data/cdm_ms"
data_dir=""

# 服务是否进行绑定节点 ip， yes/no
# 默认是 no，不进行绑定
bind=no
[root@localhost bin]#

4 部署主备集群/主从集群

[root@localhost bin]# cd /opt/dmncdb/cdm/bin
[root@localhost bin]# ls
cdm_encrypt_tool  cdm_monitor  cdm_ms_install.sh  cdm_ms_uninstall.sh  cdm_server  cdm_server.key  data  log  scripts  services
[root@localhost bin]# ./cdm_ms_install.sh

5 部署日志

[root@localhost bin]# ./cdm_ms_install.sh
