通过图形界面安装oracle 19c client

1. 服务器配置检查

1) 检查/tmp目录，至少需要400MB空间
2) 检查swap分区
	256 MB: 3 times the size of RAM
	Between 256 MB and 512 MB: 2 times the size of RAM
	Between 512 MB and 2 GB: 1.5 times the size of RAM
	Between 2 GB and 16 GB: Equal to the size of RAM
	More than 16 GB: 16 GB
3) oinstall用户组和oraInventory目录
	sudo groupadd oinstall
	sudo groupadd dba
	sudo usermod -g oinstall -G dba oracle
	mkdir -p /u01/app/oracle/product/19.0.0/client_1
	mkdir -p /u01/app/oraInventory
	chown -R oracle.oinstall /u01/app
4) 用户和组
	/usr/sbin/useradd -u 54321 -g oinstall -G dba oracle
5) 确认有root权限或者root跳转权限
6) 修改oracle用户环境变量
	export ORACLE_HOME=/u01/app/oracle/product/19.0.0/client_1
	export LD_LIBRARY_PATH=$ORACLE_HOME/lib
	export PATH=$ORACLE_HOME/bin:$PATH
	export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
	export ORACLE_BASE=/u01/app/oracle

2. 检查服务器硬件配置

1) 确保远程弹框可以使用
	# xhost + RemoteHost
2) 检查硬件和内存配置
检查RAM(至少256M）
	# grep MemTotal /proc/meminfo

	检查SWAP
	# grep SwapTotal /proc/meminfo

	检查tmp
	# df -h /tmp

	#查看内存和架构
	# free
	# uname -m

	确认共享内存(/dev/shm)挂载合理并且大小足够
	df -h /dev/shm

3. 配置操作系统

1) 安装基础依赖包
	yum install -y bc binutils elfutils-libelf elfutils-libelf-devel
	yum install -y fontconfig-devel
	yum install -y glibc
	yum install -y glibc-devel
	yum install -y ksh
	yum install -y libaio
	yum install -y libaio-devel
	yum install -y libXrender
	yum install -y libX11
	yum install -y libXau
	yum install -y libXi
	yum install -y libXtst
	yum install -y libgcc
	yum install -y libnsl
	yum install -y librdmacm
	yum install -y libstdc++
	yum install -y libstdc++-devel
	yum install -y libxcb
	yum install -y libibverbs
	yum install -y make
	yum install -y policycoreutils
	yum install -y policycoreutils-python-utils
	yum install -y smartmontools
	yum install -y sysstat
2) 安装图形依赖包
	yum -y isntall xdpyinfo  xauth  xhost

4. 安装客户端

1) 如果是redhat 8.0版本，执行下面的命令，否则会报supportedOSCheck相关错误
	su - oracle
	export CV_ASSUME_DISTID=RHEL7.6

	Export  CV_ASSUME_DISTID=OEL7.8
2) 设置变量
	Su - oracle
	Exprot DISPLAY=*.*.*.*:0.0
	Xhost +
3) 安装
	./runInstaller
4) 用root用户执行脚本
 /u01/app/oraInventory/orainstRoot.sh

5. 配置oracle用户环境变量

export ORACLE_BASE=/u01/app/oracle
export INVENTORY_LOCATION=/u01/app/oraInventory
export ORACLE_HOME=/u01/app/oracle/product/19.0.0/client_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$PATH
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK  #根据需要选择
umask 022

6. 发送环境变量信息给用户
