此时需要慢慢等待······
当出现以下画面时,请照做
要执行配置脚本,请执行以下操作:
1.打开一个终端窗口
2.以"root"身份登陆
3.运行脚本
/opt/inventory/orainstRoot.sh
/opt/oracle/product/11.2.0/db_1/root.sh
4.返回此窗口并按"Enter"键继续
编辑监听配置文件 /opt/src/database/response/netca.rsp
修改以下参数
INSTALL_TYPE=""custom"" # 安装的类型
LISTENER_NUMBER=1 # 监听器数量
LISTENER_NAMES={
"LISTENER"} # 监听器的名称列表
LISTENER_PROTOCOLS={
"TCP;1521"} # 监听器使用的通讯协议列表
LISTENER_START=""LISTENER"" # 监听器启动的名称
执行命令:
$ /opt/oracle/product/11.2.0/db_1/bin/netca /silent /responseFile /opt/src/database/response/netca.rsp
查看监听程序是否运行
$ netstat -tnulp | grep 1521
开启监听:
/opt/oracle/product/11.2.0/db_1/bin/lsnrctl start
关闭监听:
/opt/oracle/product/11.2.0/db_1/bin/lsnrctl stop
编辑数据库实例文件 /opt/src/database/response/dbca.rsp
修改以下参数
RESPONSEFILE_VERSION ="11.2.0" // 不要变哦
OPERATION_TYPE ="createdatabase" // 操作为创建实例
GDBNAME ="orcl" // 数据库实例名
SID ="orcl" // 实例名字
TEMPLATENAME = "General_Purpose.dbc" // 建库用的模板文件
SYSPASSWORD = "oracle" // SYS管理员密码
SYSTEMPASSWORD = "oracle" // SYSTEM管理员密码
SYSMANPASSWORD= "oracle"
DBSNMPPASSWORD= "oracle"
optFILEDESTINATION =/opt/oracle/oraopt // 数据文件存放目录
RECOVERYAREADESTINATION=/opt/oracle/flash_recovery_area // 恢复数据存放目录
CHARACTERSET ="AL32UTF8" // 字符集
NATIONALCHARACTERSET= "AL16UTF16" // 字符集
TOTALMEMORY ="1638" // 1638MB,物理内存2G*80%。
执行命令:
$ /opt/oracle/product/11.2.0/db_1/bin/dbca -silent -responseFile /opt/src/database/response/dbca.rsp
$ ps -ef | grep ora_ | grep -v grep
修改启动和关闭实例的程序
修改文件: /opt/oracle/product/11.2.0/db_1/bin/dbstart
/opt/oracle/product/11.2.0/db_1/bin/dbshut
将
ORACLE_HOME_LISTNER=$1
修改为
ORACLE_HOME_LISTNER=/opt/oracle/product/11.2.0/db_1
修改文件: /etc/oratab
将
orcl:/opt/oracle/product/11.2.0:N
修改为
orcl:/opt/oracle/product/11.2.0:Y
启动或者关闭实例
启动实例:
/opt/oracle/product/11.2.0/db_1/bin/dbstart
关闭实例:
/opt/oracle/product/11.2.0/db_1/bin/dbshut
Root用户模式下:
# chmod +x /etc/rc.d/rc.local
修改文件 /etc/rc.d/rc.local
在文件最后追加以下内容:
su oracle -lc "/opt/oracle/product/11.2.0/db_1/bin/lsnrctl start"
su oracle -lc "/opt/oracle/product/11.2.0/db_1/bin/dbstart"
先登录下数据库
# su - oracle
$ sqlplus / as sysdba
