BAD PASSWORD: The password is shorter than 8 characters

Retype new password:

确认密码

passwd: all authentication tokens updated successfully.

[root@localhost heming]# id oracle

查看新建的oracle用户

uid=1001(oracle) gid=1002(dba) groups=1002(dba)

2.创建oracle数据库安装目录

<pre style="text-align:justify;text-justify:inter-ideograph;background:#FAFAFC">[heming@localhost ~]$ su root</pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">Password: </pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost heming]# mkdir -p /data/oracle　　#oracle****数据库安装目录</pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost heming]# mkdir -p /data/oraInventory　　#oracle****数据库配置文件目录</pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost heming]# mkdir -p /data/database　　#oracle****数据库软件包解压目录</pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost heming]# cd /data</pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost data]# ls　　#****创建完毕检查一下</pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">database oracle oraInventory</pre>

<pre style="text-align:justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost data]# chown -R oracle:oinstall /data/oracle　　#****设置目录所有者为oinstall用户组的oracle用户</pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost data]# chown -R oracle:oinstall /data/oraInventory</pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost data]# chown -R oracle:oinstall /data/database</pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost data]# </pre>

3.修改OS系统标识(修改文件 /etc/RedHat-release )

<pre style="text-align:justify;text-justify:inter-ideograph;background:#FAFAFC">[heming@localhost data]$ su root</pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">Password: </pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost data]# cat /proc/version </pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">Linux version 3.10.0-327.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.3 20140911 (Red Hat 4.8.3-9) (GCC) ) #1 SMP Thu Nov 19 22:10:57 UTC 2015</pre>

<pre style="text-align:justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost data]# cat /etc/redhat-release　　</pre>

<pre style="text-align:justify;text-justify:inter-ideograph;background:#FAFAFC">CentOS Linux release 7.2.1511 (Core) </pre>

<pre style="text-align:justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost data]# vi /etc/redhat-release</pre>

<pre style="text-align:
justify;text-justify:inter-ideograph;background:#FAFAFC">进入到编辑模式了，点击键盘上的“insert”按钮，再将第一行替换为redhat-7，按Esc按钮，输入:wq，注意这里有一个冒号，再回车，保存并退出. </pre>

<pre style="text-align:justify;text-justify:inter-ideograph;background:#FAFAFC">[root@localhost data]# cat /etc/redhat-release </pre>

4、关闭防火墙

关闭防火墙：systemctl stop firewalld.service

禁止使用防火墙：systemctl disable firewalld.service

<v:shapetype id="_x0000_t75" coordsize="21600,21600" o:spt="75" o:preferrelative="t" path="m@4@5l@4@11@9@11@9@5xe" filled="f" stroked="f"><v:stroke joinstyle="miter"><v:formulas></v:formulas><v:path o:extrusionok="f" gradientshapeok="t" o:connecttype="rect"></v:path></v:stroke></v:shapetype><v:shape id="图片_x0020_16" o:spid="_x0000_i1063" type="#_x0000_t75" alt="说明: " style="width:284.25pt;height:71.25pt;visibility:visible;
mso-wrap-style:square"><v:imagedata src="file:///C:\Users\Administrator\AppData\Local\Temp\msohtmlclip1\01\clip_image001.png" o:title=""></v:imagedata></v:shape>

5、关闭selinux

进入编辑状态：vi /etc/selinux/config

将SELINUX的值改为disabled，保存并退出。

<v:shape id="图片_x0020_15" o:spid="_x0000_i1062" type="#_x0000_t75" alt="说明: " style="width:284.25pt;height:141.75pt;visibility:visible;
mso-wrap-style:square"><v:imagedata src="file:///C:\Users\Administrator\AppData\Local\Temp\msohtmlclip1\01\clip_image002.png" o:title=""></v:imagedata></v:shape>

6、修改内核参数

进入编辑状态：vi /etc/sysctl.conf

在最后添加如下代码：

net.ipv4.icmp_echo_ignore_broadcasts = 1

net.ipv4.conf.all.rp_filter = 1

fs.file-max = 6815744

fs.aio-max-nr = 1048576

kernel.shmall = 2097152

kernel.shmmax = 2147483648

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

保存并退出。

使配置参数立即生效：sysctl -p

<v:shape id="图片_x0020_14" o:spid="_x0000_i1061" type="#_x0000_t75" alt="说明: " style="width:284.25pt;height:213.75pt;
visibility:visible;mso-wrap-style:square"><v:imagedata src="file:///C:\Users\Administrator\AppData\Local\Temp\msohtmlclip1\01\clip_image003.png" o:title=""></v:imagedata></v:shape>

7、对oracle用户设置限制，提高软件运行性能

进入编辑状态：vi /etc/security/limits.conf

找到最后一行# End of file，在它上面空行处添加如下代码：

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

保存并退出。

8、配置用户的环境变量

进入编辑状态：vi /home/oracle/.bash_profile

在最后添加如下代码：

export ORACLE_BASE=/data/oracle #oracle数据库安装目录

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

export ORACLE_SID=orcl #oracle启动数据库实例名

export ORACLE_TERM=xterm

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.ZHS16GBK

保存并退出。

使上述配置立即生效：source /home/oracle/.bash_profile

9、上述都搞定了，便可以进行oracle的安装了。

10、切换用户到oracle用户。如下图所示，单击桌面右上角的三角形图标，单击你的用户名称，单击切换用户。输入你前面设置的oracle账户登录密码。将oracle解压后的文件复制到桌面上，名字为database，双击进入该文件夹，空白处单击右键，选择Open in Terminal进入终端界面。

CenotOS6中文环境下安装Oracle 11g 中文乱码解决办法

Linux下安装Oracle11g，安装界面乱码问题解决方法：

解决安装时中文是"囗囗囗囗囗囗囗囗"

1.进入刚解压的database/stage/Components/oracle.jdk/1.5.0.17.0/1/DataFiles/all.jar

2.在桌面新建一个文件夹命名为fallback，下载中文字体（zysong.ttf）放入里面去。

3.用归档管理器打开all.jar它进入/jdk/jre/lib/fonts/把在桌面建好的fallback文件夹拖放进来，完成后的目录结构应该是/jdk/jre/lib/fonts/fallback/zysong.ttf。

2)startup

5、再开一个终端，敲入如下命令启动监听和oem

1)启动监听 lsnrctl start

2)启动oem服务 emctl start 注意oem服务启动后会有一个网址的提示，利用这个网址就可以通过ie用图形界面操作oracle了</pre>

经过各种尝试和折腾后，最终还是把问题给搞定了，步骤如下：

1. 停止监听器

$ lsnrctl stop

2. 停止 oracle 数据库

3. 修改 $ORACLE_HOME/network/admin/listener.ora，将文件内容中 HOST 的值改为正确的 IP（192.168.132.41），如：

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

  (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.132.41)(PORT = 1521))

)

)

4. 修改 $ORACLE_HOME/network/admin/tnsnames.ora，将文件内容中 HOST 的值改为正确的 IP（192.168.132.41），如：

ORCL =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.132.41)(PORT = 1521))

(CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = orcl)

)

)

5. 修改 /etc/sysconfig/network，

需要进入root身份才能进行修改

将文件内容改为：

| |

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=hemw-pc

因为修改完这个文件后需要重启操作系统才会生效，所以在不重启操作系统的情况下需要同时执行一下：# hostname hemw-pc

6. 修改 /etc/hosts，在文件的最后新增如下内容：

| |

192.168.68.129 hemw-pc hemw-pc.mycompany.com.cn

4、在终端里面敲下面的命令启动数据库 1)sqlplus / as sysdba
2)startup
