redhat7.6安装oracle11g

1. 系统重启后登录oracle用户，启用vncserver

[root@cbhsdb217 ~]# su - oracle
[oracle@cbhsdb217:/home/oracle]$vncserver

2. 启动vnc客户端

3. 修改database安装包775的权限
   
4. 在database目录下运行安装程序（redhat7下装11g有BUG必须执行下面的命令）

[oracle@cbhsdb217 database]$ ./runInstaller -jreLoc /etc/alternatives/jre_1.8.0

5. 安装oracle11g
   
   
   
   
   
   
   
   
   
   
   

[root@cbhsdb217 ~]# /tmp/CVU_11.2.0.4.0_oracle/runfixup.sh 

[root@cbhsdb217 backup]# rpm -ivh compat-libstdc-33-3.2.3-72.el7.x86_64.rpm

~~[root@cbhsdb217 backup]# rpm -ivh pdksh-5.2.14-30.x86_64.rpm~~    -----不能安装，使用下面强制安装
[root@cbhsdb217 backup]# rpm -ivh --force --nodeps pdksh-5.2.14-30.x86_64.rpm 

swap分区不足，本次我选择了忽略！

[root@cbhsdb217 backup]# su - oracle
[oracle@cbhsdb217:/home/oracle]$cd $ORACLE_HOME
[oracle@cbhsdb217:/oracle/app/oracle/product/11.2.0/db_1]$cd sysman/lib 
[oracle@cbhsdb217:/oracle/app/oracle/product/11.2.0/db_1/sysman/lib]$cp ins_emagent.mk ins_emagent.mk.bak   ---备份一份
[oracle@cbhsdb217:/oracle/app/oracle/product/11.2.0/db_1/sysman/lib]$vi ins_emagent.mk

root用户下执行脚本

[root@cbhsdb217 ~]# /oracle/app/oraInventory/orainstRoot.sh 
[root@cbhsdb217 ~]# /oracle//app/oracle/product/11.2.0/db_1/root.sh 

配置监听

[oracle@cbhsdb217:/home/oracle]$netca

创建数据库

[oracle@cbhsdb217:/home/oracle]$dbca

[root@cbhsdb217 ~]# vi /etc/sysctl.conf
[root@cbhsdb217 ~]# sysctl -p     ---生效
