之前没搞过linux,这次客户的系统装的linux,项目发布环境及数据库已经安装好了。由于要急着上线,所以就边摸索边处理了。简单记下,以备后查。

先看版本:

用户给的不是root账号,所以,有些目录访问不了,有些文件也操作不了。先前遇到很多问题,不过也都解决了。

首先把Oracle给启动。

由于不是root用户,所以切换到oracle时总是提示密码,,输了几次不对,没办法。后来想到用sudo来试试。果然,可以。


然后就是启动oracle及查看状态了。

  • -- 查看监听的方法   
  • lsnrctl stat   
  • lsnrctl start  
  • 进入sqlplus,切换至sysdba

  • sqlplus /nolog  
  • conn /as sysdba  
  • 创建相关的用户及表空间。

  •   
  •   
  • 创建好后将从其他机器导出的PDM上传至本机中。

    之前直接将文件传到/home的该用户下,导致oracle用户无法访问,于是在/tmp/下建了个更新文件夹,PDM上传至该处。可以正常访问。

    由于用了oracle的数据泵,所以先要建立文件目录。

  • 查看是否建立好

  • 处理好后。现在可以导入相关数据了。先退出sqlplus。至oracle用户下。

    导入语句

  • impdp ABCDEFG/ABCDEFG@localhost/adb DIRECTORY=dump_dir DUMPFILE=ABCDEFG2012_20120725_1146.DMP remap_schema=ABCDEFG2012:ABCDEFG remap_tablespace=ABCDEFG2012:ABCDEFG  
  • 这里需要注意下,先前没有使用 remap_schema 与 remap_tablespace 这两个参数,始终无法导入成功。由于是不同的表空间,所以,加上这两个参数后问题解决。可以正常数据导入了。
    数据导入后用客户端查看了下,相关数据均正常显示。现在更改项目数据库连接参数了。切换至普通用户,进入项目目录下,找到 jdbc.properties,使用vi进行编辑。

    vi之前也没用过,边找资料边操作。总共用了3个命令,那就是进入先按 i 进入插入模式,编辑完成后按 esc 然后 :x,保存并退出。如果不想保存的话可以 :q! 这个命令强制退出。

    这样就差不多可以了。重启项目服务

  • service resin restart  
  • 第一次操作Linux,绕了不少弯子,也出现了不少问题,不过好在都给解决了。稍微总结下:

    chown myuser /var/www/webapps  //这个命令可以更改所有者,更改后对相关文件就可以有操作权限了。

    chmod 777 /var/www/webapps //这个命令可以更改用户操作权限。777就是最大权限咯。

    还有个最后才发现了,直接用 su - root可以切换到root用户下。原来客户给我的这个用户的权限是相当大的。
