在上一篇文章中，我寫了使用VAGRANT 快速安裝ORACLE DATABASE 18C 。在這篇文章中，我們將學習如何使用Vagrant訪問Oracle 18c資料庫。首先我們需要檢查VM的狀態。使用上篇文章用到的Vagrant global-status命令。

PS G:\VM DATA\vagrant-boxes\OracleDatabase\18.3.0> vagrant global-status
idnameproviderstatedirectory
----------------------------------------------------------------------------------------------
b1be299oracle-18c-vagrant virtualbox running G:/VM DATA/vagrant-boxes/OracleDatabase/18.3.0

The above shows information about all known Vagrant environments
on this machine. This data is cached and may not be completely
up-to-date (use "vagrant global-status --prune" to prune invalid
entries). To interact with any of the machines, you can go to that
directory and run Vagrant, or you can use the ID directly with
Vagrant commands from any directory. For example:
"vagrant destroy 1a2b3c4d"

接下來我們可以開啟Virtual Box虛擬機器看一下狀態。通過上一篇文章我們的作業系統自動建立了一個叫oracle-18c-vagrant的虛擬機器。

然後我們可以使用vagrant ssh命令登陸進主機。

PS G:\VM DATA\vagrant-boxes\OracleDatabase\18.3.0> vagrant ssh

切換到Oracle使用者之後，我們就可以執行一系列的命令來玩Oracle 18c了。

[oracle@oracle-18c-vagrant ~]$ ps -ef | grep pmon
oracle800410 23:20 ?00:00:00 ora_pmon_ORCLCDB

我們安裝VM，預設在oracle使用者的home目錄下。有個setPassword.sh的指令碼。這個指令碼是給sys,system,pdb_admin設定密碼的。

[oracle@oracle-18c-vagrant ~]$ ls -lrt
total 4
-rwxr-xr-x. 1 root root 784 Oct1 23:21 setPassword.sh
[oracle@oracle-18c-vagrant ~]$ more setPassword.sh

ORACLE_PWD=$1
ORACLE_SID="`grep $ORACLE_HOME /etc/oratab | cut -d: -f1`"
ORACLE_PDB="`ls -dl $ORACLE_BASE/oradata/$ORACLE_SID/*/ | grep -v pdbseed | awk '{print $9}' | cut -d/ -f6`"
ORAENV_ASK=NO
source oraenv

sqlplus / as sysdba << EOF
ALTER USER SYS IDENTIFIED BY "$ORACLE_PWD";
ALTER USER SYSTEM IDENTIFIED BY "$ORACLE_PWD";
ALTER SESSION SET CONTAINER=$ORACLE_PDB;
ALTER USER PDBADMIN IDENTIFIED BY "$ORACLE_PWD";
exit;
EOF

要想從虛擬機器中退出來，輸入exit就行了。

[oracle@oracle-18c-vagrant ~]$ exit
logout
[vagrant@oracle-18c-vagrant ~]$ exit
logout
Connection to 127.0.0.1 closed.

輸入vagrant halt就關閉虛擬機器了，如果你要刪除整個虛擬機器，執行vagrant destroy命令。

PS G:\VM DATA\vagrant-boxes\OracleDatabase\18.3.0> vagrant halt
==> oracle-18c-vagrant: Attempting graceful shutdown of VM...

當然我們還能執行一些命令檢視配置情況，例如vagrant port可以檢視埠情況，vagrant ssh-config可以檢視ssh配置資訊。

PS G:\VM DATA\vagrant-boxes\OracleDatabase\18.3.0> vagrant port
The forwarded ports for the machine are listed below. Please note that
these values may differ from values configured in the Vagrantfile if the
provider supports automatic port collision detection and resolution.

1521 (guest) => 1521 (host)
5500 (guest) => 5500 (host)
PS G:\VM DATA\vagrant-boxes\OracleDatabase\18.3.0> vagrant ssh-config
