环境:
HOST | IP | OS | |
主机1 | 100011 | 10.0.0.11 | CentOS6.6 |
主机2 | 100012 | 10.0.0.12 | CentOS6.6 |
为了省事,直接关闭iptables,selinux,以下配置都为10.0.0.11上的配置,10.0.0.12也要做相同配置(个别地方须修改,如ip等)
一、安装配置rsync
1、安装
[root@100011 /]# yum install -y rsync xinetd
[root@100011 /]# service xinetd start&&chkconfig xinetd on
2、创建配置文件
[root@100011 /]# mkdir /var/log/rsyncd ##存放日志文件
[root@100011 /]# vi /etc/rsyncd.conf
######内容######
uid=root
gid=root
use chroot=no
max connections=10
strict modes=yes
port=873
address=10.0.0.11 ##本地要监听的IP地址
[data] ##数据同步模块名,可自定义名字
path=/nfs-storage
comment=nfs mirror
ignore errors
read only=no
list=no
secrets file=/etc/rsync.pas
hosts allow=*
pid file=/var/run/rsyncd.pid
lock file=/var/run/rsync.lock
log file=/var/log/rsyncd/rsyncd.log
3、配置认证文件
[root@100011 /]# echo "abcd,.1234">/etc/rsync.pas
[root@100011 /]# chmod 600 /etc/rsync.pas
rsync配置结束,不要添加开机启动,通过keepalived启动
二、安装配置sersync
1、下载安装
wget http://sersync.googlecode.com/files/sersync2.5.4_64bit_binary_stable_final.tar.gz
或
wget https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/sersync/sersync2.5.4_64bit_binary_stable_final.tar.gz
[root@100011 ~]#tar -zxvf sersync2.5.4_64bit_binary_stable_final.tar.gz
cd GNU-lINUX-x86/
mkdir /usr/local/sersync
mkdir /usr/local/sersync/conf
mkdir /usr/local/sersync/bin
mkdir /usr/local/sersync/log
cp confxml.xml /usr/local/sersync/conf
cp sersync2 /usr/local/sersync/bin/
ln -s /usr/local/sersync/bin/sersync2 /usr/bin/sersync2
2、配置
vi /usr/local/sersync/conf/confxml.xml
红色标注为我个人添加或修改部份
sersync配置结束,不要添加开机启动 ,通过keepalived启动
三、安装本置keepalived
1、安装
[root@100011 /]# yum install -y keepalived
2、配置
[root@100011 /]# cat /etc/keepalived/keepalived.conf
! Configuration File for keepalived
global_defs {
notification_email {
}
notification_email_from [email protected]
smtp_server 192.168.200.1
smtp_connect_timeout 30
router_id 100011 不能重复,我用的ip地址作为标识
}
vrrp_instance VI_1 {
state BACKUP 两台都配置BACKUP
interface eth0
virtual_router_id 248 同一vrrp组要一样,我用的vip
# use_vmac uvmac 开始想整vmac没成功
# vmac_xmit_base
priority 100 另一台上配置小于100
advert_int 1
nopreempt 另一台不需要
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
10.0.0.248/24
}
notify_master /usr/local/sersync/tomaster.sh
notify_backup /usr/local/sersync/tobackup.sh
}
}
四、安装配置nfs
1、服务器端,100012也要做相同配置
[root@100011 /]#yum install -y nfs-utils rpcbind
[root@100011 /]#vi /etc/exports
/nfs-storage/webdata 10.0.0.0/24(rw,no_root_squash)
[root@100011 /]service rpcbind start&&service nfs start
[root@100011 /]chkconfig nfs on&&chkconfig rpcbind on
[root@100011 /]#exportfs
/nfs-storage/webdata
10.0.0.0/24
2、客户端通过autofs挂载
[root@100010 /]vi /etc/auto.nfs 假定100010为其中一台apache服务器
webdata -rw,bg,soft,udp,rsize=524288,wsize=524288 10.0.0.248:/nfs-storage/webdata
[root@100010 /]vi /etc/auto.master
#
# Sample auto.master file
# This is a 'master' automounter map and it has the following format:
# mount-point [map-type[,format]:]map [options]
# For details of the format look at auto.master(5).
#
/misc /etc/auto.misc
#
# NOTE: mounts done from a hosts map will be mounted with the
# "nosuid" and "nodev" options unless the "suid" and "dev"
# options are explicitly given.
#
/net -hosts
#
# Include central master map if it can be found using
# nsswitch sources.
#
# Note that if there are entries for /net or /misc (as
# above) in the included master map any keys that are the
# same will not be seen as the first read key seen takes
# precedence.
#
+auto.master
/mydata /etc/auto.nfs --timeout=20 新加内容
service autofs restart
在/mydata下执行ls 发现为空,因通过autofs自动挂载配置,要有访问才会挂载,如执行cd webdata 便可发现挂载成功。上同的配置--timeout=20是说20秒空闲,就umount.
后记:过上一段时间,发现rsync的日志较大,通过logrotate分割rsync的日志,具体怎样使用,百度!!!
[root@100011 /]#vi /etc/logrotate.d/rsyncd
/var/log/rsyncd/rsyncd.log {
notifempty
daily
rotate 7
}
部署过多次后后,我咋觉得要把这简单的事描述清楚,咋就这么困难呢,唉,语文没学好,。我的疑惑:比如挂载的时候通过udp(默认是tcp,我把它改成udp和把vmac固定,是为了看服务器端故障转移,看是不是要快些)。
重要东东在附件。checktb是根据官方脚本简单修改的,另也尝试rsync+sersync双向同步,但发现有点问题。(有兴趣自行测试吧)
脚本执行
[root@100011 /]crontab -e
* * * * * /usr/local/sersync/checktb.sh
* * * * * sleep 10; /usr/local/sersync/checktb.sh
* * * * * sleep 20; /usr/local/sersync/checktb.sh
* * * * * sleep 30; /usr/local/sersync/checktb.sh
* * * * * sleep 40; /usr/local/sersync/checktb.sh
* * * * * sleep 50; /usr/local/sersync/checktb.sh
第一次写,由于我是菜鸟,简单的都还不懂,跟别说深层次的。肯定有疏漏不当之处,欢迎拍砖,拍了后但也请指正。
