在Redhat 7.2上安裝Oracle 12c
環境：
OS: 帶有圖形界面的Red Hat Enterprise Linux Server release 7.2 (Maipo)
Oracle:12c Enterprise Edition Release 12.2.0.1.0
主機名：node01
步驟：
[root@node01 ~]# groupadd oinstall
[root@node01 ~]# groupadd dba
[root@node01 ~]# groupadd oper
[root@node01 ~]# useradd -g oinstall -G dba,oper oracle
[root@node01 ~]# passwd oracle
增加以下內容, node01為hostname
127.0.0.1 node01
切換到oracle用戶（這裡要進入oracle用戶的圖形界面），解壓安裝包，並運行runInstaller程序
[oracle@node01 ~]$ unzip linuxx64_12201_database.zip
[oracle@node01 ~]$ cd database/
[oracle@node01 database]$ ls
install response rpm runInstaller sshsetup stage welcome.html
[oracle@node01 database]$ export DISPLAY=:0.0
[oracle@node01 database]$ xhost +
access control disabled, clients can connect from any host
[oracle@node01 database]$ ./runInstaller

之後自動進入圖形界面：
運行到這一步時，有很多要求不符合，可以嘗試點擊Fix & Check Again，會出現如下界面，需要開一個新的終端，使用root用戶執行腳本：
執行完成之後，有一些不符要求的地方已經被修復，剩餘的直接勾選Ignore All即可：
上面這一步，在運行到Execute Root Scripts時，會出現如下界面，只需要使用root用戶執行裡面提到的兩個腳本即可：
另個，如果遇到如下的報錯，直接關掉，再點擊Retry就能過去：
修改home目錄下的.bash_profile文件，增加以下內容
export ORACLE_HOME=/home/oracle/app/oracle/product/12.2.0/dbhome_1
export ORACLE_SID=orcl
export LD_LIBRARY_PATY=/usr/lib:$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$PATH
並使之立即生效
[oracle@node01 ~]$ source .bash_profile
[oracle@node01 ~]$ sqlplus / as sysdba
