Centos7下安装Oracle11g r2
我的centos7是在virtualbox下安装的,安装Oracle安装了好久好久,最开始的时候在网上找的两个文章,按照步骤装,有一篇写着装的时候有灰色的竖线,直接按space键或者鼠标右键closed关闭掉就OK,我想着这多好,安装了好几次,都失败了,而且,在安装之前我也没有备份,我又有强迫症,稍有和步骤不一样,或者安装依赖包失败了,就又要从头再来,有时候会很生气,真的就把它们统统卸载了,又重新安装virtualbox,centos,安装Oracle之前的准备工作,安装Oracle,折腾了特别久,我要写一个安装步骤记录下来我经过惨痛的教训之后得到的经验。
一、安装的硬件要求
1.内存:
RAW
|
Swap |
1G至2G | 1.5倍 |
2G至16G | 同RAW相等 |
16G以上 | 16G |
二、环境准备
安装包:- linux.x64_11gR2_database_1of2.zip
- linux.x64_11gR2_database_2of2.zip
1 [cindyma@localhost ~]$ su root #切换到root 2 Password: 3 [root@localhost]# groupadd oinstall #创建用户组oinstall 4 [root@localhost]# groupadd dba #创建用户组dba 5 [root@localhost]# useradd -g oinstall -g dba -m oracle #创建oracle用户,并加入到oinstall和dba用户组 6 [root@localhost]# passwd oracle #设置用户oracle的登陆密码,不设置密码,在CentOS的图形登陆界面没法登陆 7 Changing password for user oracle. 8 New password: # 密码 9 BAD PASSWORD: The password is shorter than 8 characters 10 Retype new password: # 确认密码 11 passwd: all authentication tokens updated successfully. 12 [root@localhost]# id oracle # 查看新建的oracle用户 13 uid=1001(oracle) gid=1002(dba) groups=1002(dba)

我的版本当然对应的是这个版本:Oracle Linux 7 and Red Hat Enterprise Linux 7
它没有要求说要安装elfutils和unixODBC包,但是等安装Oracle检查安装前准备时,会提示说缺少这两个包,所以一并安装
有时候使用yum安装的时候,会提示another app is currently holding the yum lock,这个时候打开另外一个terminal,在root用户下输入
#rm -f /var/run/yum.pid
强制关掉yum进程

四、Oracle图形界面选项
去掉 I wish to receive security updates via My Oracle Support.
点击 "Next >"
选择第一项 Create and configure a database
点击 "Next >"
点击 "Next >"
选择英语 English(根据系统默认选择好了)
点击 "Next >"
选择第一个企业版
确定数据软件的安装路径,自动读取前面Oracle环境变量中配置的值
点击 "Next >",
"Character Sets"选择第二项或者第三项中的"Unicode standard UTF-8..."
点击 "Next >"
选择第二项,并设置密码
点击 "Next >"
按照提示信息一个一个解决。
点击 "Finsh"
在此过程中,安装界面会变成黑色,有一长条出现(其实是一个提示框),调整高度与宽度查看
INFO: /lib64/libstdc++.so.5: undefined reference to `memcpy@GLIBC_2.14'
INFO: collect2: error: ld returned 1 exit status
INFO: make: *** [ctxhx] Error 1
网上说是glibc的版本2.17过高所致(高于2.14),解决办法:
进入管理员权限安装glibc-static
1 [oracle@localhost ~]# su - root 2 password 3 [root@localhost ~]# yum -y install glibc-static
该软件包包含一个静态链接库,地址是:/usr/lib64/libc.a
修改/data/oracle/product/11.2.0/db_1/ctx/lib/ins_ctx.mk,将
ctxhx: $(CTXHXOBJ)
$(LINK_CTXHX) $(CTXHXOBJ) $(INSO_LINK)
修改为:
ctxhx: $(CTXHXOBJ)
-static $(LINK_CTXHX) $(CTXHXOBJ) $(INSO_LINK) /usr/lib64/libc.a
点击Retry继续安装。
修改/data/oracle/product/11.2.0/db_1/sysman/lib/ins_emagent.mk,将
$(MK_EMAGENT_NMECTL)修改为:$(MK_EMAGENT_NMECTL) -lnnz11
点击Retry继续安装。
安装完成后的两个小问题
1.Linux下sqlplus不能使用光标箭头
解决办法:安装rlwrap包
1)下载rlwrap压缩包(我下载的是rlwrap-0.37.tar.gz);
2)yum安装readline
[root@localhost oracle]#yum -y install readline*
3)解压,安装
[root@localhost oracle]#tar -xzvf rlwrap-0.37.tar.gz [root@localhost oracle]#cd rlwrap-0.37.tar.gz [root@localhost oracle]#./configure [root@localhost oracle]#make [root@localhost oracle]#make install
4)切换到oracle用户下,编辑bash_profile文件
[oracle@localhost ~]vi .bash_profile
在最后添加
alias sqlplus='rlwrap sqlplus'
alias rman='rlwrap rman'
保存退出,执行source .bash_profile使其生效。
或者直接不修改bash_profile文件,直接在输入sqlplus命令前加上rlwrap即可(我修改了bash_profile文件,重启系统还是要重新输入source命令使其生效,我之后直接在sqlplus命令前加rlwrap)。
这样在sqlplus中就可以使用上下左右键来查看历史纪录了。
2.vim中文乱码
设置~下或者oracle用户下的.vimrc文件,加上fileencodings、enc、fencs,代码如下:
vim ~/.vimrc #或者vim /home/oracle(用户名)/.vimrc
#添加如下代码
set fileencodings=utf-8,gb2312,gb18030,gbk,ucs-bom,cp936,latin1
set enc=utf8
set fencs=utf8,gbk,gb2312,gb18030
