csync2安装

源码编译的时候错误多多呀，改成yum了，很简单的OK了！！！！

yum install xinetd libgpg-error libgpg-error-devel libgcrypt libgcrypt-devel libtasn1 libtasn1-devel sqlite sqlite-devel librsync librsync-devel nettle nettle-devel gnutls-devel gnutls gnutls-utils  bison bison-devel bison-runtime flex -y

wget
tar zxvf sqlite-2.8.17.tar.gz
cd sqlite-2.8.17
./configure && make && make install
cd ..
echo "/usr/local/lib" >> /etc/ld.so.conf
ldconfig

wget
tar zxvf csync2-1.34.tar.gz
cd csync2-1.34
./configure
make && make install
make cert
echo "csync2 30865/tcp" >> /etc/services
cd ..

vim /etc/xinetd.d/csync2
service csync2
 {
 disable = no
 protocol = tcp
 flags = REUSE
 socket_type = stream
 wait = no
 user = root
 group = root
 server = /usr/local/sbin/csync2
 server_args = -i
 #only_from = 192.168.169.112 192.168.169.113 192.168.169.114
}

chkconfig xinetd on
service xinetd start

生成密钥
csync2 -k /etc/csync2.key

将key复制到另一台机器
scp -P22 /etc/csync2.key
scp -P22 /etc/csync2.cfg

/etc/hosts
192.168.2.11 server1
192.168.2.12 server2

hostname server1

vim /etc/csync2.cfg
..

 backup-generations 3;
 auto younger; //同步以最新的文件为标准更新.
 }
 #
 # prefix homedir

 # on *: /home;
# }

group server
{
        host server1 server2;
        key /etc/csync2.key;

}

 

csync2 -vvv -T 测试配置是否正解
csync2 -xv 执行同步命令
csync2 -xvvv 执行同步命令，并显示详细信息
