##创建配置grid,oracle用户

/usr/sbin/groupadd -g 54323 oper
/usr/sbin/useradd -u 54321 -g oinstall -G dba,oper oracle
echo "SIGasmlib"|passwd --stdin oracle
id oracle
添加oracle用户环境变量

#创建安装目录
mkdir -p /u01/app/oracle/product/19.0.0/db_1
mkdir -p /u01/install
chown -R oracle.oinstall /u01
chmod -R 775 /u01
注意：从18C 开始 database同grid为简单安装模式
解压 zip包至 oracle $ORACLE_HOME中
unzip LINUX.X64_193000_db_home.zip -d $ORACLE_HOME
oracle用户
cd $ORACLE_HOME
./runInstaller
数据库软件安装
执行脚本后点击OK
数据库dbca建库
单实例模式
先不配置后面手动netca配置
根据安装需求进行配置
netca创建监听
netmgr 配置静态监听
