安装前准备

修改资源限制（root用户下）

# 查看最大用户线程数
ulimit -u

# 执行如下命令使最大用户线程数临时生效，重启后无效
ulimit -u 65536

# 执行执行如下命令将最大用户线程数写入/etc/security/limits.conf文件，重启后参数永久生效
echo "
* soft nproc 65536
* hard nproc 65536
" >> /etc/security/limits.conf

开放端口

ymp安装的默认端口如下：

YMP监听 数据库监听 主机间通信 yasom yasagent
8090 8091 8092 8093 8094

方式一：关闭防火墙（测试环境，可以考虑关闭）

# 查看是否关闭
[root@dba236 mnt]# systemctl status firewalld.service
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled)
   Active: active (running) since Wed 2024-04-10 10:25:50 EDT; 1 weeks 5 days ago
     Docs: man:firewalld(1)
 Main PID: 871 (firewalld)
   CGroup: /system.slice/firewalld.service
           └─871 /usr/bin/python2 -Es /usr/sbin/firewalld --nofork --nopid

Apr 10 10:25:49 dba236 systemd[1]: Starting firewalld - dynamic firewall daemon...
Apr 10 10:25:50 dba236 systemd[1]: Started firewalld - dynamic firewall daemon.
[root@dba236 mnt]# firewall-cmd --add-port=1688/tcp --permanent
success
[root@dba236 mnt]# firewall-cmd --reload
success


# 关闭防火墙
systemctl stop firewalld 

# 关闭开机自启
systemctl disable firewalld

方式二：添加防火墙白名单（建议生产环境，按需开启，安全有放心）

# 查看防火墙已开放端口
firewall-cmd --zone=public --list-ports

# 添加端口到防火墙（以8090为例）
firewall-cmd --zone=public --add-port=8090/tcp --permanent

# 重新加载防火墙策略
firewall-cmd --reload

# 若需删除白名单中的端口，执行
firewall-cmd --zone=public --remove-port=8090/tcp --permanent

用户准备

创建一个用户用于安装YMP，以YMP为例，在用户创建和授权后，后续所有安装步骤均在该用户下操作。

# 新建YMP用户
# useradd -d /home/ymp -m ymp
# passwd ymp

上传YMP安装包至/home/ymp目录下然后解压：

# 切换至YMP安装目录
$ cd /home/ymp/
$ unzip yashan-migrate-platform-v23.2.1.3-linux-x86-64.zip

OCI环境设置（oracle迁移到yashanDB必备）

PS: ymp仅支持OCI 19.19.0.0及以上版本

$ cd /home/ymp/
[ymp@yashan ~]$ unzip instantclient-basic-linux.x64-19.19.0.0.0dbru.el9.zip
修改安装包及目录
chown -R ymp:ymp instantclient_19_19

进入安装目录

$ cd /home/ymp/yashan-migrate-platform/
\# 执行安装命令，这里--db指定的是内置数据库 -- 这里db后面需要指定数据库的安装包，如果是迁移oracle，则需要指定OCI路径

2.2. 卸载YMP

$ cd /home/ymp/yashan-migrate-platform/
 $ sh bin/ymp.sh uninstall
 
 # 使用uninstall功能时可携带-f参数，强制清理环境
 $ sh bin/ymp.sh uninstall -f
  
 # 验证
 $ ps -ef | grep yas
 ymp       20840  6322  0 10:02 pts/14   00:00:00 grep --color=auto yas

从Oracle 迁移数据到YashanDB

登录

登录YMP平台，地址IP:PORT,默认端口8090，默认账号密码admin/admin

修改密码：（Asdf123.）

【数据源管理】-> 添加数据源

image-20241114150711604

PS： 配置完后，顺手做下“测试连接”，确定连通性

1、源端配置（配置连接、端口、账号密码信息）

YAS-00402 failed to connect socket, errno 111, error message "Connection refused"
在打开yasql / as sysdba时候报错，我是重新安装数据库解决的，网上没有找到好的办法。
-- [yashan@yashan install]$ ./bin/yasboot package install -t hosts.toml -i yashandb-personal-23.2.3.100-linux-x86_64.tar.gz

-- [yashan@yashan instance]$ yasboot cluster password set -n yasdb_123 -c yashandb

#yanshandb上面新建用户并授权。
