CentOS 6.5 部署Unison双向同步服务
环境介绍: 服务器 | IP | Server1 | 192.168.30.131 | Server2 | 192.168.30.132 |
1、添加主机互信: a、添加host文件(在Server1、Server2分别操作): [iyunv@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): [iyunv@localhost ~]# sed -i "s/HOSTNAME=.*/HOSTNAME=Server1/g" /etc/sysconfig/network [iyunv@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: [iyunv@Server1 ~]# ssh-keygen -t rsa [iyunv@Server1 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@Server2 d2、在主机Server2上操作: [iyunv@Server2 ~]# ssh-keygen -t rsa [iyunv@Server2 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@Server1
2、Unison安装
2.1、安装编译工具:Objective Caml compiler [iyunv@Server1 soft]# cd ocaml-3.10.2+rc1/ [iyunv@Server1 ocaml-3.10.2+rc1]# ./configure [iyunv@Server1 ocaml-3.10.2+rc1]# make world opt [iyunv@Server1 ocaml-3.10.2+rc1]# make install && echo OK
2.2、安装Unison: [iyunv@Server1 unison-2.13.16]# cd ../unison-2.13.16 [iyunv@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: [iyunv@Server1 unison-2.13.16]# make UISTYLE=text THREADS=true [iyunv@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: [iyunv@Server2 unison-2.13.16]# mkdir /root/bin [iyunv@Server2 unison-2.13.16]# cp unison /root/bin/
重新编译: [iyunv@Server1 unison-2.13.16]# make install && echo OK
2.3、修改配置文件; [iyunv@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 [iyunv@Server1 ~]# mkdir /data [iyunv@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 [iyunv@Server1 ~]# unison -servercmd [iyunv@Server1 data]# unison -servercmd=/root/bin/unison
Contacting server...
Looking for changes
Waiting for changes from server
Reconciling changes local Server2

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
