目录规划
/yashandb/install：安装目录
/yashandb/data：数据目录
mkdir -p /yashandb/{install,data}
解压安装介质
上传yashandb-personal-23.1.1.100-linux-x86_64.tar.gz至/opt
--解压
cd /opt
tar -xvf yashandb-personal-23.1.1.100-linux-x86_64.tar.gz -C /yashandb/install
--赋予权限
chown -R yashan:yashan /yashandb
chmod -R 755 /yashandb
安装步骤
数据库安装过程中将实例自动切换成OPEN阶段，并创建名为yashandb的数据库。

问题处理
cpu和memory config check failed
问题描述
安装数据库时提示cpu和memory检测失败，查看官方文档最低配置为：cpu:2C memory:4G
[yashan@localhost bin]$ yasboot package install -t hosts.toml -i yashandb-personal-23.1.1.100-linux-x86_64.tar.gz
192.168.40.152
ip: cpu cores is less than 2
ip: memroy is less than 4096MB
config check failed
处理办法
升级硬件配置，cpu:2C,内存5G
hosts.toml is not exist
问题描述
安装数据库时提示hosts.toml参数文件不存在
[yashan@localhost conf]$ yasboot package install -t hosts.toml -i yashandb-personal-23.1.1.100-linux-x86_64.tar.gz
hosts.toml is not exist
处理办法
未切换到配置文件目录，切换到hosts.toml文件所在目录重新安装成功
YASPW-00002 password complexity failed
问题描述
重置sys密码文件时提示密码复杂度失败
[yashan@localhost instance]$ yaspwd file=yasdb.pwd password=yashan
YASPW-00002 password complexity failed for SYS user : password must contain at least 8 characters
解决办法
密码复杂度不够，增加密码复杂度解决
yaspwd file=yasdb.pwd password=Admin@2023
YAS-00404 address 2023 is an invalid IPV4
问题描述
sys用户登录时提示YAS-00404 address 2023 is an invalid IPV4

YashanDB SQL Personal Edition Release 23.1.1.100 x86_64
YAS-00404 address 2023 is an invalid IPV4 URL/Ip address/hostname
解决办法
由于密码中含有@特殊字符，和Oracle一样需特殊处理。其他字符则不受影响
