CentOS 6.5 部署Unison双向同步服务
环境介绍:
服务器IP
Server1192.168.30.131
Server2192.168.30.132
1、添加主机互信:  a、添加host文件(在Server1、Server2分别操作):    [root@localhost ~]#echo -e "192.168.30.131 Server1\n192.168.30.132 Server2" >> /etc/hosts  b、更改主机名(在Server1、Server2分别操作):    [root@localhost ~]# sed -i "s/HOSTNAME=.*/HOSTNAME=Server1/g" /etc/sysconfig/network    [root@localhost ~]# hostname Server1  c、退出重新登录就会显示出主机名  d、添加互信    d1、在主机Server1上操作:    [root@Server1 ~]# ssh-keygen -t rsa    [root@Server1 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@Server2    d2、在主机Server2上操作:    [root@Server2 ~]# ssh-keygen -t rsa    [root@Server2 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@Server1  2、Unison安装    unison各种版本下载地址:
    http://www.seas.upenn.edu/~bcpierce/unison//download.html
    unison编译器下载地址:
    http://caml.inria.fr/pub/distrib/ocaml-3.10        2.1、安装编译工具:Objective Caml compiler    [root@Server1 soft]# cd ocaml-3.10.2+rc1/    [root@Server1 ocaml-3.10.2+rc1]# ./configure    [root@Server1 ocaml-3.10.2+rc1]# make world opt    [root@Server1 ocaml-3.10.2+rc1]# make install && echo OK        2.2、安装Unison:    [root@Server1 unison-2.13.16]# cd ../unison-2.13.16    [root@Server1 unison-2.13.16]# make UISTYLE=text THREADS=true      此时会产生一个错误:      /bin/sh: etags: command not found      make[1]: [tags] Error 127 (ignored)
      make[1]: Leaving directory `/soft/unison-2.13.16'      解决方法:      yum -y install ctags-etags    重新编译:    [root@Server1 unison-2.13.16]# make UISTYLE=text THREADS=true    [root@Server1 unison-2.13.16]# make install && echo OK      此时如果报错:      mv /root/bin//unison /tmp/unison-10301      mv: cannot stat `/root/bin//unison': No such file or directory
      make: [doinstall] Error 1 (ignored)
      cp unison /root/bin/
      cp: cannot create regular file `/root/bin/': Is a directory
      make: *** [doinstall] Error 1      解决方法:      [root@Server2 unison-2.13.16]# mkdir /root/bin      [root@Server2 unison-2.13.16]# cp unison /root/bin/     重新编译:
    [root@Server1 unison-2.13.16]# make install && echo OK        2.3、修改配置文件;    [root@Server1 data]# cat /root/.unison/default.prf     # Unison preferences file
    root = /data
    root = ssh://root@Server2//data
    #path = www
    #ignore = Path wp-content/tmp
    ignore = Path wp-config.php #忽略wp-config.php文件 相当于rsync的exclude
    #nodeletion = /data
    batch = true
    maxthreads = 300
    #repeat = 1
    owner = true
    group = true
    perms = -1
    fastcheck = false
    sshargs = -C
    xferbycopying = true
    log = true
    logfile = /tmp/unison.log     2.4、创建同步目录/data    [root@Server1 ~]# mkdir /data    [root@Server1 ~]# echo "aa" >> aa.txt        2.5、在Server2上同样操作之上步骤,此处略过        2.6、测试同步    [root@Server1 ~]# unison -servercmd    [root@Server1 data]# unison -servercmd=/root/bin/unison
    Contacting server...
    Looking for changes
    Waiting for changes from server
    Reconciling changes    local Server2
    new file ----> bb.txt
    local : new file modified on 2015-08-19 at 14:42:45 size 5 rw-r--r-- user=0 group=0
    Server2 : absent
    Propagating updates
    UNISON started propagating changes at 14:43:10 on 19 Aug 2015
    [BGN] Copying bb.txt
    from /data
    to //Server2//data
    [END] Copying bb.txt
    UNISON finished propagating changes at 14:43:10 on 19 Aug 2015
    Saving synchronizer state
    Synchronization complete (1 item transferred, 0 skipped, 0 failures)
    [root@Server1 data]#
