- 一、检查服务器硬件和内存配置：
1．使用以下命令确定服务器上的物理RAM大小：
grep MemTotal /proc/meminfo
2．确定配置的交换空间的大小：
grep SwapTotal /proc/meminfo
3．确定/tmp目录中可用的空间量：
df -h /tmp
4．确定系统上的可用RAM和磁盘交换空间量：
free
5．确定系统体系结构是否可以运行该软件：
uname -m
验证处理器体系结构是否与要安装的Oracle软件版本匹配。例如，对于x86-64位系统，您应该看到以下内容：
x86_64
如果您没有看到预期的输出，则无法在此系统上安装该软件。
6.验证共享内存（/dev/shm）是否已正确安装且大小足够：
df -h /dev/shm
二、依赖包安装：
yum install -y binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc glibc-common glibc-devel libaio libaio-devel libgcc libstdc++ libstdc++-devel make sysstat ld-linux.so.2
- 三、创建组和用户
groupadd oinstall
useradd oracle -g oinstall
passwd oracle
- 四、创建目录
mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/app/
mkdir /opt/oracle(客户端安装介质解压目录)
mkdir /u01/app/oracle/11.2/client(客户端的安装目录)
- 五、安装
配置文件所在位置：/opt/oracle/client/response/client_install.rsp

静默安装客户端
./runInstaller -silent -responseFile /opt/oracle/client/response/client_install.rsp -ignoreSysPrereqs
• -silent 以静默方式运行安装程序。
• -noconfig 禁止在安装期间运行配置助手，而是执行纯软件安装。
注意：
必须要用oracle用户启动
不要指定响应文件的相对路径。如果指定相对路径，则安装程序将失败。
- 六、root用户执行脚本
/u01/app/oracle/11.2/client/root.sh
- 七、配置环境变量
vim .bash_profile
export ORACLE_HOME =/u01/app/oracle/11.2/client
export NLS_LANG（根据情况)
export NLS_DATE_FORMAT ="YYYY-MM-DD HH24:Mi:SS"
export LD_LIBRARY_PATH= $ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$PATH
生效环境变量
source .bash_profile
- 八、登陆sqlplus
sqlplus / nolog
- 九、客户端连接数据库
- 十、常见问题
问题：
尝试使用system/sys用户登录服务器的数据库，始终显示无效的用户名/密码。
ERROR:
ORA-01017: invalid username/password; logon denied
解决方法：
1.执行命令sqlplus / as sysdba登录
2.执行select username from dba_users查看所有用户
3.解锁账户并设置密码
解锁用户命令格式为：ALTER USER 用户名 UNLOCK
SQL> alter user system account unlock;
设置新密码命令格式为：ALTER USER 用户名 IDENTIFIED BY 新密码
SQL> alter user system identified by 123456;
