安装环境： redhat5.5   VirtualBox4.3.12  oracle10g

在虚拟机环境下，直接安装的是带图形界面redhat5.5-server，便于后来方面安装oracle

一 安装部分

1. 安装前的包检查

采用iso光盘挂载作为 yum源安装

[rhel-server]
name=local server
baseurl=file:///mnt/cdrom/Server   //挂载光盘文件为yum源
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

安装如下的包，注意版本号和包依赖

binutils-2*   elfutils-libelf-0*  elfutils-libelf-devel-0*  elfutils-libelf-devel-static-0*  setarch-2*
make-3*  glibc-2*  glibc-devel-2*  glibc-common-2*  glibc-header-*
libaio-0* libaio-devel-0*  compat-libstdc++-33-3*   kernel-headers-*  ksh-*  compat-gcc-34-3*
compat-gcc-34-c++-3*  libgcc-4*  libstdc++-4*   libstdc++-devel-4*   libgomp-4*
gcc-4*  gcc-c++-4*   libXp-1*  libXt  openmotif22-*  compat-db-4*   sysstat-7*
unixODBC-2*  unixODBC-devel-2*
rpm -q binutils elfutils-libelf elfutils-libelf-devel elfutils-libelf-devel-static setarch make glibc glibc-devel glibc-common glibc-headers libaio libaio-devel compat-libstdc++-33 kernel-headers ksh compat-gcc-34 compat-gcc-34-c++ libgcc libstdc++ libstdc++-devel libgomp gcc gcc-c++ libXp libXt openmotif compat-db sysstat unixODBC unixODBC-devel

2.修改系统参数

内核参数  /etc/sysctl.conf

 kernel.shmall = 2097152kernel.shmmax = 2147483648kernel.shmmni = 4096kernel.sem = 250 32000 100 128fs.file-max = 65536net.ipv4.ip_local_port_range = 1024 65000net.core.rmem_default=262144net.core.rmem_max=262144net.core.wmem_default=262144net.core.wmem_max=262144

sysctl -p 使参数生效

关闭seLinux        /etc/selinux/config

SELINUX=disabled

设置oracle用户的shell limit   /etc/security/limits.conf

oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

oracle10g 只支持到了redhat-4， 修改/etc/redhat-release

redhat-4

3. 创建Oracle用户组 及目录

 groupadd -g 500 dbagroupadd -g 501 oinstalluseradd -g oinstall -G dba -s /bin/bash -u 501 oraclepasswd oraclemkdir -p /oracle/app/oracle/product/10.2/db_1chown -R oracle:oinstall /oraclechmod -R 775 /oracle

4. 修改oracle用户 .bash_profile

export ORACLE_BASE=/oracle/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2/db_1
export ORACLE_SID=bi4db
export PATH=$PATH:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export CLASSPATH

5.解压安装

unzip 10201_database_linux64.zip
./runInstaller  // 遇到没有执行权限文件 chmod +x xxx

二、进程启动

1.oracle监听器listener

lsnrctl start
lsnrctl stop
/oracle/app/oracle/product/10.2/db_1/bin/tnslsnr LISTENER -inherit

2.oracle OEM启动

emctl start dbconsole
emctl stop dbconsole
http://192.168.30.6:1158/em  sys/pwd sysdba登陆

3.isql*plus的启动

isqlplusctl start
isqlplusctl stop

4. 数据库启动停止

[oracle@dbtest 10201_database_linux64]$ sqlplus

三、测试scott/tiger

解锁scott用户，登陆测试

SQL> conn scott;
Enter password:
ERROR:
ORA-28000: the account is locked
SQL> conn system;
Enter password:
Connected.
SQL>
SQL> alter user scott account unlock;
User altered.
SQL> show user;
USER is "SCOTT"
