# 节点服务器挂载Nas存储
**主节点挂载Nas（从节点同）**
1. 背景 
   主从节点同步和通信需要使用到共享存储
   
   
2. 解决思路 
   在需要共享节点挂载共享文件到对于目录（xxx.xxx.xxx.xxx为SFS服务器地址）
   ```
   yum  install  nfs-utils
   mount -t nfs -o vers=3,nolock xxx.xxx.xxx.xxx:/  /data
   ```
   
   
3. 设置软连接（主从均配置） 
   - 将ecology以下目录复制到/data目录下(从节点不做)
     ```
     album formmode  mobilemode mobile  email  filesystem  images  images_face   images_frame   LoginTemplateFile  messager  m_img  others  page      upgrade   wui
     mkdir /usr/weaver/ecology/LoginTemplateFile（从做）
     mkdir /usr/weaver/ecology/others（从做）
     cp -r /usr/weaver/ecology/album /data
     cp -r /usr/weaver/ecology/formmode /data
     cp -r /usr/weaver/ecology/mobilemode /data
     cp -r /usr/weaver/ecology/mobile /data
     cp -r /usr/weaver/ecology/email /data
     cp -r /usr/weaver/ecology/filesystem /data
     cp -r /usr/weaver/ecology/images /data
     cp -r /usr/weaver/ecology/images_face /data
     cp -r /usr/weaver/ecology/images_frame /data
     cp -r /usr/weaver/ecology/LoginTemplateFile /data
     cp -r /usr/weaver/ecology/messager /data
     cp -r /usr/weaver/ecology/m_img /data
     cp -r /usr/weaver/ecology/others /data
     cp -r /usr/weaver/ecology/page /data
     cp -r /usr/weaver/ecology/upgrade /data
     cp -r /usr/weaver/ecology/wui /data
     ```
     
   
   - 将ecology\\WEB-INF下(从节点不做)
     ```
     mkdir –p /usr/weaver/ecology/WEB-INF/lib/keys
     cp -r /usr/weaver/ecology/WEB-INF/securityRule/ /data
     cp -r /usr/weaver/ecology/WEB-INF/securityXML/ /data
     cp -r /usr/weaver/ecology/WEB-INF/service /data
     cp -r /usr/weaver/ecology/WEB-INF/lib/keys /data
     cp -r /usr/weaver/ecology/WEB-INF/weaver_security_rules.xml /data
     cp -r /usr/weaver/ecology/WEB-INF/weaver_security_config.xml /data
     cp -r /usr/weaver/ecology/WEB-INF/hrmsettings.xml /data
     ```
     复制到/data目录下
     
   
   - 备份（主从做）
     ```
     cd  /usr/weaver/ecology/
     mv  album album.bak
     mv  images  images.bak
     mv  images_face  images_face.bak
     mv  formmode  formmode.bak
     mv  mobile  mobile.bak
     mv  mobilemode  mobilemode.bak
     mv  images_frame  images_frame.bak
     mv  LoginTemplateFile  LoginTemplateFile.bak
     mv  m_img  m_img.bak
     mv  filesystem  filesystem.bak
     mv  page  page.bak
     mv  messager  messager.bak
     mv  email  email.bak
     mv  wui  wui.bak
     mv  others  others.bak
     mv  upgrade  upgrade.bak
     cd  /usr/weaver/ecology/WEB-INF
     mv  service  service.bak
     mv  lib/keys   lib/keys.bak
     mv  securityRule  securityRule.bak
     mv  securityXML  securityXML.bak
     mv  weaver_security_config.xml  weaver_security_config.xml.bak
     mv  weaver_security_rules.xml  weaver_security_rules.xml.bak
     mv  hrmsettings.xml hrmsettings.xml.blk
     ```
     
   
   - 建立共享文件夹的软链接：（主从做）
     ```
     ln -sf /data/album /usr/weaver/ecology/album
     ln -sf /data/filesystem   /usr/weaver/ecology/filesystem
     ln -sf /data/images   /usr/weaver/ecology/images
     ln -sf /data/images_face   /usr/weaver/ecology/images_face
     ln -sf /data/images_frame   /usr/weaver/ecology/images_frame
     ln -sf /data/LoginTemplateFile   /usr/weaver/ecology/LoginTemplateFile
     ln -sf /data/messager   /usr/weaver/ecology/messager
     ln -sf /data/m_img   /usr/weaver/ecology/m_img
     ln -sf /data/page   /usr/weaver/ecology/page
     ln -sf /data/wui   /usr/weaver/ecology/wui
     ln -sf /data/email   /usr/weaver/ecology/email
     ln -sf /data/others   /usr/weaver/ecology/others
     ln -sf /data/service   /usr/weaver/ecology/WEB-INF/service
     ln -sf /data/securityRule   /usr/weaver/ecology/WEB-INF/securityRule
     ln -sf /data/securityXML   /usr/weaver/ecology/WEB-INF/securityXML
     ln -sf /data/hrmsettings.xml   /usr/weaver/ecology/WEB-INF/hrmsettings.xml
     ln -sf /data/weaver_security_rules.xml /usr/weaver/ecology/WEB-INF/weaver_security_rules.xml
     ln -sf /data/weaver_security_config.xml  /usr/weaver/ecology/WEB-INF/weaver_security_config.xml
     ln -sf /data/keys   /usr/weaver/ecology/WEB-INF/lib/keys
     ln -sf /data/formmode   /usr/weaver/ecology/formmode
     ln -sf /data/mobilemode   /usr/weaver/ecology/mobilemode
     ln -sf /data/mobile   /usr/weaver/ecology/mobile
     ln -sf /data/upgrade   /usr/weaver/ecology/upgrade
     ```
     
   
   - 在需要共享节点随机启动时，挂载共享文件(注意空隙使用tab)
     ```
     vi /etc/fstab
     xxx.xxx.xxx.xxx:/     /data                   nfs     defaults        0 0
     ```
