修改完后,启用新的配置:
# sysctl -p
# yum -y install binutils* compat-libcap1* compat-libstdc++* gcc* gcc-c++* glibc* glibc-devel* ksh* libaio* libaio-devel* libgcc* libstdc++* libstdc++-devel* libXi* libXtst* make* sysstat* elfutils* unixODBC* unzip lrzsz net-tools
# groupadd oinstall #创建安装oracle程序用户组 # groupadd dba #创建DBA用户组 # useradd -g dba -m oracle #创建用户oracle 并加入到dba组 # usermod -a -G oinstall oracle #将用户oracle加入到oinstall组 # passwd oracle #修改用户oracle的密码
# id oracle #查看用户oracle的信息
# mkdir -p /opt/oracle #创建oracle主目录 # mkdir -p /opt/inventory #创建oralce配置目录 # mkdir -p /opt/src #创建oracle压缩包解压目录 # chown -R oracle:oinstall /opt/oracle #修改目录权限 # chown -R oracle:oinstall /opt/inventory # chown -R oracle:oinstall /opt/src # ll /opt #查看目录权限

export PATH export ORACLE_BASE=/opt/oracle export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 export ORACLE_SID=orcl export ORACLE_UNQNAME=orcl export PATH=$ORACLE_HOME/bin:/usr/sbin:$PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib export LANG=C export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
修改完后立即启用:
# source /home/oracle/.bashrc
# unzip linux.x64_11gR2_database_1of2.zip -d /opt/src/ # unzip linux.x64_11gR2_database_2of2.zip -d /opt/src/ # chown -R oracle:oinstall /opt/src/ # ll /opt/src/

# reboot
进入Oracle用户
# su oracle
oracle.install.option=INSTALL_DB_SWONLY # 安装类型 ORACLE_HOSTNAME=oracle.server # 主机名称 UNIX_GROUP_NAME=oinstall # 安装组 INVENTORY_LOCATION=/opt/inventory # INVENTORY目录 SELECTED_LANGUAGES=en,zh_CN # 选择语言 ORACLE_HOME=/opt/oracle/product/11.2.0/db_1 # oracle_home ORACLE_BASE=/opt/oracle # oracle_base oracle.install.db.InstallEdition=EE # oracle版本 oracle.install.db.DBA_GROUP=dba # dba用户组 oracle.install.db.OPER_GROUP=oinstall # oper用户组 oracle.install.db.config.starterdb.type=GENERAL_PURPOSE # 数据库类型 oracle.install.db.config.starterdb.globalDBName=orcl # globalDBName oracle.install.db.config.starterdb.SID=orcl # SID oracle.install.db.config.starterdb.characterSet=AL32UTF8 # 默认数据库编码 oracle.install.db.config.starterdb.memoryLimit=800 # 自动管理内存的最小内存(M)oracle.install.db.config.starterdb.password.ALL=oracle # 设定所有数据库用户使用同一个密码 DECLINE_SECURITY_UPDATES=true
安装oracle
$ /opt/src/database/runInstaller -silent -responseFile /opt/src/database/response/db_install.rsp -ignorePrereq
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
关于监听的开机和关闭
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" DATAFILEDESTINATION =/opt/oracle/oradata // 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
查看实例是否运行
$ 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 SQL> select * from v$version;BANNER--------------------------------------------------------------------------------Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production PL/SQL Release 11.2.0.1.0 - Production CORE 11.2.0.1.0 Production TNS for Linux: Version 11.2.0.1.0 - Production NLSRTL Version 11.2.0.1.0 - Production
