使用Xmanager在CentOs5.5 安装oracle11g r2

先决条件：要有图形化界面，如果系统没有图形化界面，则进行安装图形化界面

1、 yum grouplist  

2、yum groupinstall "X Window System"

3、yum groupinstall "GNOME Desktop Environment"；注： yum groupremove "GNOME Desktop Environment"

使用Xmanager：

    配置CentOs: vim /etc/inittab

                id:3:initdefault

                把3改为5   --linux启动时为图形界面

                vim /etc/gdm/custom.conf,修改为：          

                            [security]

                            AllowRemoteRoot=true #允许root登陆

                            [xdmcp]

                            Enable=true #开启xdcmp服务

                            Port=177 #指定服务端口

                然后重启服务器:init 6

   配置Xmanager: 

使用Xbrowser登陆

安装oracle:

1、将压缩包使用ftp传上去后，使用unzip来进行解压

2、在根目录下创建oracle的组与和用户

   mkdir u01

   groupadd oinstall

   groupadd dba

   useradd -g oinstall -G dba -d /u01/oracle oracle

   passwd oracle oracle

3、进入u01把database目录剪切到该目录

   cd /u01

  mv /root/database/ .

4、更改u01r的权限让oracle和oinstall有权限操作u01

  chown oracle:oinstall -R /u01

5、切换到oracle用户，并设置该用户的环境变量

   su - oracle

   vim .bash_profile,在其末尾添加

        ORACLE_SID=test   

        ORACLE_BASE=/u01

        ORACLE_HOME=$ORACLE_BASE/oracle 

        LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH

        PATH=$ORACLE_HOME/bin:$PATH

            export ORACLE_SID ORACLE_BASE ORACLE_HOME LD_LIBRARY_PATH PATH

6、 安装oracle 11gR2 依赖的组件包(切换到root用户)

     #需要以下组件：

7、调整内核参数

    vim /etc/security/limits.conf, 在其末尾添加

        oracle              soft    nproc  2047

        oracle              hard    nproc  16384

        oracle              soft    nofile 1024

        oracle              hard    nofile 65536

        oracle              soft    stack  10240

    vim /etc/sysctl.conf,在其末尾添加

        fs.aio-max-nr = 1048576

        fs.file-max = 6815744

        kernel.shmall = 2097152

        kernel.shmmax = 4294967295

        kernel.shmmni = 4096

        kernel.sem = 250 32000 100 128

        net.ipv4.ip_local_port_range = 9000 65500

        net.core.rmem_default = 262144

        net.core.rmem_max = 4194304

        net.core.wmem_default = 262144

        net.core.wmem_max = 1048576

    最后让其生效：sysctl -p

7、修改login文件

     vim /etc/pam.d/login,在其末尾添加

        session    required     /lib/security/pam_limits.so

        session    required     pam.limits.so

8、运行Xmanager

    如果Xmanager连接不上centos，则先用root用户执行iptables -F

     打开终端运行：xhost +

     切换oracle用户：su - oracle

     再运行：xhost local:oracle

    进入/u01/database

    运行./runInstaller

    按照界面提示，一步一步执行

9、若之前安装数据库的时候只安装了数据库软件，则现在来创建数据库

   进入到oracle用户运行dbca

  按照提示一步一步执行，注意各用户的密码与编码格式

10、配置监听

   进入到oracle用户运行netca

   按照提示一步一步执行

11、如果使用sqlplus出现（ sqlplus: error while loading shared libraries）

解决方法：

[root@fw55 lib]# getenforce

Enforcing

[root@fw55 lib]# /usr/sbin/setenforce 0 

[root@fw55 lib]# cd /etc/selinux

[root@fw55 selinux]# ls

config  restorecond.conf  semanage.conf  targeted

[root@fw55 selinux]# vi config 

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

#       enforcing - SELinux security policy is enforced.

#       permissive - SELinux prints warnings instead of enforcing.

#       disabled - SELinux is fully disabled.

SELINUX=disabled     

# SELINUXTYPE= type of policy in use. Possible values are:

#       targeted - Only targeted network daemons are protected.

#       strict - Full SELinux protection.

SELINUXTYPE=targeted

 把SELINUX设置为disabled 就好了，保存后退出。
