Redhat Enterprise Edition 5安装Oracle 11g
Redhat Enterprise Edition 5安装Oracle 11g
系统安装:
选择尽量多的开发软件,X Windows为必需。
一.创建必要的用户,组和目录
#mkdir -p /u01/Oracle
#groupadd dba
#groupadd oinstall
#useradd -g oinstall -G dba /u01/oracle oracle
#passwd oracle bobo365
#chown -R oracle:oinstall /u01 把u01目录赋予oracle用户oinstall组
#ls -l 查看命令是否生效
二.安装前准备
(1)用rpm -qa|grep * 查看是否已安装如下软件包,如没安装则安装之。
binutils-2.15.92.0.2-18
compat-libstdc++-33.2.3-47.3
elfutils-libelf-0.97-5
elfutils-libelf-devel-0.97-5
glibc-2.3.9.4-2.19
glibc-common-2.3.9.4-2.19
glibc-devel-2.3.9.4-2.19
gcc-3.4.5-2
gcc-c++-3.4.5-2
libaio-devel-0.3.105-2
libaio-0.3.105-2
libgcc-3.4.5
libstdc++-3.4.5-2
libstdc++-devel-3.4.5-2
make-3.80-5
sysstat-5.0.5
unixODBC-2.2.11
unixODBC-devel-2.2.11
(2)修改/etc/sysctl.conf文件,设置linux内核,在最后加入以下内容:
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144
结束后#sbin/sysctl -p 使系统生效
(3) 修改 /etc/security/limits.conf文件,加入如下内容:
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
(4)修改/etc/profile文件,加入如下内容:
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
三.进入oracle用户设置oracle的环境变量
#su oracle
打开 v .bash_profile 加入
ORACLE_BASE=/u01
ORACLE_HOME=$ORACLE_BASE/oracle
ORACLE_SID=cache(数据库名字)
PATH=$ORACLE_HOME/bin:$PATH
export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH
四.开始安装
在系统图形界面下,使用root用户,,#xhost + localhost
#xhost +
关闭访问限制,允许任何访问。oracle安装完用xhost - 关闭。
将数据库安装文件database移动到/u01目录下
#mv database /u01
#chown -R oracle:oinstall /u01/database
su oracle 在database目录下$./runInstaller
选择高级安装,进行自定义安装
在安装中,假如出现一个关于oraInventory目录的警告 ,点击OK继续,在随后的窗口中
将/oraInventory修改为/u01/oraInventory即可.
随后参数都是默认,在安装中会弹出一个要求执行u01/oraInventory/oraInstRoot.sh和/u01/oracle
/root.sh的提示框,可在secureCRT中,以ROOT用户执行这两个文件 ,一定要注意大小写,其入进行End of
installtion窗口,安装结束.
进入/u01/app/oracle/product/11.2.0/dbhome_2/bin,输入
./netca & 命令进行侦听配置.其中参数一律默认即可.可以用ps -ef 查看该服务是否已启用.
输入./dbca命令,进行数据库的创建.
选择gernel purpose,在SID和全局名称中,选择你在.bash_profile中创建的SID.
在Character Sets字符集选项中选择第2项AL32UTF8.
完成.
存在的问题,将在第二稿中解决。
1、无法使用sqlplus、netmr等命令;
2、无法启动emctl start dbconsole,无法使用web方式进行数据库管理;
3、SSH远程连接工具下如何启用X Windows工具进行管理。
