篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了CentOS 6.5 部署Unison双向同步服务相关的知识,希望对你有一定的参考价值。
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):
[[email protected] ~]#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):
[[email protected] ~]# sed -i "s/HOSTNAME=.*/HOSTNAME=Server1/g" /etc/sysconfig/network
[[email protected] ~]# 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:
[[email protected] ~]# ssh-keygen -t rsa
[[email protected] ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
d2、在主机Server2上操作:
[[email protected] ~]# ssh-keygen -t rsa
[[email protected] ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
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
[[email protected] soft]# cd ocaml-3.10.2+rc1/
[[email protected] ocaml-3.10.2+rc1]# ./configure
[[email protected] ocaml-3.10.2+rc1]# make world opt
[[email protected] ocaml-3.10.2+rc1]# make install && echo OK
2.2、安装Unison:
[[email protected] unison-2.13.16]# cd ../unison-2.13.16
[[email protected] 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:
[[email protected] unison-2.13.16]# make UISTYLE=text THREADS=true
[[email protected] 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:
[[email protected] unison-2.13.16]# mkdir /root/bin
[[email protected] unison-2.13.16]# cp unison /root/bin/
重新编译:
[[email protected] unison-2.13.16]# make install && echo OK
2.3、修改配置文件;
[[email protected] data]# cat /root/.unison/default.prf
# Unison preferences file
root = /data
root = ssh://[email protected]//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
[[email protected] ~]# mkdir /data
[[email protected] ~]# 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
[[email protected] ~]# unison -servercmd
[[email protected] 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)
