最近需要安裝oracle，然后網上查了一下教程，在centos7.7上安裝成功，運行正常。這里記錄一下。

環境：

硬件4核/8G RAM/100G 存儲

centos7.7（64bit）

oracle11g（官網下載的）

步驟（轉載）：

第一個腳本preinstalloracle.sh，以root用戶運行。執行完后需要重啟電腦，需要注意看一下hostname是否修改好了

 #!/bin/bash#以root用戶運行#注意修改第三行的ip為自己的ip地址echo "172.16.1.110 orcl orcl" >> /etc/hostscat >> /etc/sysconfig/network <<EOFnetwork=yeshostname=orclEOF

第二個腳本secinstalloracle.sh，以root用戶運行

第三個腳本thiinstalloracle.sh，以oracle用戶運行，su - oracle
