2.  验证需要的rpm包

rpm -q binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXext libXtst libX11 libXau libxcb libXi make sysstat

查询结果

binutils-2.27-27.base.el7.x86_64compat-libcap1-1.10-7.el7.x86_64package compat-libstdc++-33 is not installedgcc-4.8.5-28.el7.x86_64gcc-c++-4.8.5-28.el7.x86_64glibc-2.17-222.el7.x86_64glibc-devel-2.17-222.el7.x86_64package ksh is not installedlibaio-0.3.109-13.el7.x86_64package libaio-devel is not installedlibgcc-4.8.5-28.el7.x86_64libstdc++-4.8.5-28.el7.x86_64libstdc++-devel-4.8.5-28.el7.x86_64libXext-1.3.3-3.el7.x86_64libXtst-1.2.3-1.el7.x86_64libX11-1.6.5-1.el7.x86_64libXau-1.0.8-2.1.el7.x86_64libxcb-1.12-1.el7.x86_64libXi-1.7.9-1.el7.x86_64make-3.82-23.el7.x86_64sysstat-10.1.5-13.el7.x86_64

安装没有安装的仨个包

yum install -y compat-libstdc++-33yum install -y libaio-devel
yum install -y ksh

3. 修改 系统配置

vi /etc/sysctl.conf 添加或修改下面参数kernel.shmmax = 68719476736kernel.shmall = 106029312kernel.shmmni = 4096kernel.sem =250 32000 100 128net.core.rmem_default = 262144net.core.rmem_max = 4194304net.core.wmem_default = 262144net.core.wmem_max = 1262144net.ipv4.ip_local_port_range =9000 65500fs.file-max=7065536fs.aio-max-nr=1048576

修改

/etc/security/limits.conf

内容中添加如下配置。

oracle soft nproc 2047oracle hard nproc 16384oracle soft nofile 1024oracle hard nofile 65536oracle soft stack 10240oracle hard stack 10240

关闭防火墙 关闭selinux

添加用户

groupadd oinstallgroupadd dbauseradd -g oinstall -G dba oracle修改密码passwd oracle创建oracle主目录mkdir -p /u01/oracle修改目录权限chown -R oracle:oinstall /u01/oraclechmod -R 775 /u01/oracle

修改环境变量. 在/etc/profile.d目录下新增一个oracle.sh 增加内容为

ORACLE_BASE=/u01/oracle; export ORACLE_BASEORACLE_HOME=$ORACLE_BASE/product/18.3.0/db_1; export ORACLE_HOMEORACLE_SID=ora18c; export ORACLE_SIDORACLE_TERM=xterm; export ORACLE_TERMPATH=/usr/sbin:$PATH; export PATHPATH=$ORACLE_HOME/bin:$PATH; export PATHLD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATHCLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATHif [ $USER = "oracle" ]; thenif [ $SHELL = "/bin/ksh" ]; thenulimit -p 16384ulimit -n 65536elseulimit -u 16384 -n 65536fifi

重新登录 验证 环境变量正常

echo $ORACLE_HOMEecho $ORACLE_SID

4. 上传linux 的安装包文件

xftp或者其他方式

解压缩 修改 安装权限

5. 进入 GUI 图形化安装

6. dbca 建库
