redhat7.6安裝oracle11g

1. 系統重啓後登錄oracle用戶，啓用vncserver

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

2. 啓動vnc客戶端

3. 修改database安裝包775的權限
   
4. 在database目錄下運行安裝程序（redhat7下裝11g有BUG必須執行下面的命令）

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

5. 安裝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~~    -----不能安裝，使用下面強制安裝
[root@cbhsdb217 backup]# rpm -ivh --force --nodeps pdksh-5.2.14-30.x86_64.rpm 

swap分區不足，本次我選擇了忽略！

[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]$cp ins_emagent.mk ins_emagent.mk.bak   ---備份一份
[oracle@cbhsdb217:/oracle/app/oracle/product/11.2.0/db_1/sysman/lib]$vi ins_emagent.mk

root用戶下執行腳本

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

配置監聽

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

創建數據庫

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

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