[root@k8s03 ~]#

2.安装依赖包
[root@k8s03 ~]# yum -y install binutils compat-libcap1 compat-libstdc++-33 compat-libstdc++-33*.i686 elfutils-libelf-devel gcc gcc-c++ glibc*.i686 glibc glibc-devel glibc-devel*.i686 ksh libgcc*.i686 libgcc libstdc++ libstdc++*.i686 libstdc++

[root@k8s03 ~]#

3.修改内核参数
[root@k8s03 ~]# vim /etc/sysctl.conf
kernel.shmall = 2097152
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
fs.file-max = 6815744
fs.aio-max-nr = 1048576
[root@k8s03 ~]# sysctl -p
[root@k8s03 ~]# vim /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 10240
[root@k8s03 ~]# vim /etc/pam.d/login
session required pam_limits.so
[root@k8s03 ~]#

4.创建用户和添加环境变量
[root@k8s03 ~]# groupadd oinstall
[root@k8s03 ~]# groupadd dba
[root@k8s03 ~]# useradd -g oinstall -G dba oracle
[root@k8s03 ~]# passwd oracle
Changing password for user oracle.
New password:
BAD PASSWORD: The password fails the dictionary check - it is based on a dictionary word
Retype new password:
passwd: all authentication tokens updated successfully.
[root@k8s03 ~]# mkdir /u01/app/oracle/product/11.2.0.1/db_1 -p
[root@k8s03 ~]# chown -R oracle:oinstall /u01/
[root@k8s03 ~]# vim /etc/profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0.1/db_1
export ORACLE_SID=orcl
export PATH=$PATH:$ORACLE_HOME/bin
[root@k8s03 ~]# . /etc/profile

5.在windows机器安装Xmanager - Passive（图形化界面）

6.在linux使用Xmanager - Passive图形化界面
[root@k8s03 ~]# xhost +
xhost: unable to open display ""
[root@k8s03 ~]# su - oracle
[oracle@k8s03 ~]$ export DISPLAY=windows机器IP地址:0.0
[oracle@k8s03 ~]$ unzip linuxx64_12201_database.zip
