使用三台服务器:
系统:CentOS 6.8
192.168.8.169 开发服务器
192.168.8.167 线上服务器1
192.168.8.168 线上服务器2
实现思路:
在开发服务器上制定一个规则,
即只要rsync.txt存在,
线上服务器就开始进行文件同步,同步完删除该文件。
实现步骤:
(1)安装Rsync。
1、Rsync简介:
Rsync(remote synchronize)是一个远程数据同步工具,可通过LAN/WAN快速同步多台主机间的文件。
Rsync使用所谓的“Rsync算法”来使本地和远 程两个主机之间的文件达到同步,
这个算法只传送两个文件的不同部分,而不是每次都整份传送,因此速度相当快。
2、Rsync安装:
wget https://download.samba.org/pub/rsync/rsync-3.1.3.tar.gz
tar -zxvf rsync-3.1.3.tar.gz
cd rsync-3.1.3
./configure –prefix=/usr/local/rsync
make
make install
第二步:
安装inotify和inotify-tools
Centos 6和CentOS 7,已经默认安装了inotify,
如果要查看是否安装,可以使用如下命令
:
ll /proc/sys/fs/inotify
如果列出如下三项,则证明已经安装
max_queued_events
max_user_instances
max_user_watches
第三步:
安装inotify-tools工具。
wget https://jaist.dl.sourceforge.net/project/inotify-tools/inotify-tools/3.13/inotify-tools-3.13.tar.gz
tar -zxvf inotify-tools-3.13.tar.gz
cd inotify-tools-3.13
./configure
make && make install
第四步:
线上服务器的配置:
touch /etc/rsyncd.conf
vim /etc/rsyncd.conf
输入以下内容:
uid = nobody
gid = nobody
use chroot = no
max connections = 10
strict mode = no
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /usr/data/rsync/rsyncd.log
[source-code]
path = /usr/local/nginx/html/hello/
comment = this is a comment message
ignore errors
read only = no
write noly = no
hosts allow = 192.168.8.169
hosts deny = *
list = false
uid = root
gid = root
auth users = root
secrets file = /usr/local/rsync/conf/server.pass
[source-code-update]
path = /usr/local/nginx/html/hello-update/
comment = this is a comment message
ignore errors
read only = no
write noly = no
hosts allow = 192.168.8.169
hosts deny = *
list = false
uid = root
gid = root
auth users = root
secrets file = /usr/local/rsync/conf/server.pass
说明:
source-code是源代码目录。
source-code-update 是控制是否更新的目录。
然后继续在线上服务器操作:
因为nginx部署的web位置一样,
cd /usr/local/nginx/html/
mkdir -p hello/
cd /usr/local/rsync(rsync的安装位置)
mkdir -p conf/
cd conf
touch server.pass
vim server.pass
root:123abc+-
给密码文件设置访问权限:
chmod 600 server.pass
第五步:
然后对开发服务器进行配置:
touch /etc/rsyncd.conf
vim /etc/rsyncd.conf
输入以下内容:
uid = nobody
gid = nobody
use chroot = no
max connections = 10
strict mode = no
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /usr/data/rsync/rsyncd.log
[source-code]
path = /usr/local/nginx/html/hello/
comment = this is a comment message
ignore errors
read only = no
write noly = no
hosts allow = 192.168.8.169,192.168.8.167
hosts deny = *
list = false
uid = root
gid = root
auth users = root
secrets file = /usr/local/rsync/conf/server.pass
建立项目目录
cd /usr/local/nginx/html/
mkdir hello
cd /usr/local/rsync(rsync的安装位置)
mkdir -p conf/
然后还要建立一个密码文件’/usr/local/rsync/conf/server.pass’ 由于1是客户端,因此密码没有前缀
123abc+-
给密码文件设置访问权限:
chmod 600 server.pass
cp /usr/local/rsync/bin/rsync /usr/bin/
/usr/local/rsync/bin/rsync –daemon
sh datarsync.sh
第一次测试
/usr/local/bin/inotifywait \
-mrq –timefmt ‘%d/%m/%y’ \
–format ‘%T %w%f%e’ \
-e modify,delete,create,attrib \
/usr/local/nginx/html/hello/index.html \
结果:有改变时,有输出
第二次测试,输出到log:
/usr/local/bin/inotifywait \
-mrq –timefmt ‘%d/%m/%y’ \
–format ‘%T %w%f%e’ \
-e modify,delete,create,attrib \
/usr/local/nginx/html/hello/ | while read files
do
echo “${files} was rsyncd” >>/tmp/rsync.log 2>&1
done
结果:日志中有信息
第三次测试:
#!/bin/bash
src=/usr/local/nginx/html/hello/
user=root
host2=192.168.8.167
$dst2=source-code
/usr/local/bin/inotifywait \
-mrq –timefmt ‘%d/%m/%y’ \
–format ‘%T %w%f%e’ \
-e modify,delete,create,attrib \
/usr/local/nginx/html/hello/ | while read files
do
/usr/bin/rsync -vzrtopg –delete –progress –password-file=/usr/local/rsync/conf/server.pass $src $user@$host2::$dst2
echo “${files} was rsyncd” >>/tmp/rsync.log 2>&1
done
/usr/bin/rsync -vzrtopg –progress –delete root@192.168.8.169::source-code/usr/local/nginx/html/hello/* /usr/local/nginx/html/hello/
使用/usr/local/bin/inotifywait命令报错:
/usr/local/bin/inotifywait: error while loading shared libraries: libinotifytool
s.so.0: cannot open shared object file: No such file or directory
[root@db zzh]# ll /proc/sys/fs/inotify (如果有下列三项则支持inotifytools)
total 0
-rw-r–r– 1 root root 0 Sep 20 16:52 max_queued_events
-rw-r–r– 1 root root 0 Sep 20 16:52 max_user_instances
-rw-r–r– 1 root root 0 Sep 20 16:52 max_user_watches
解决:
ln -s /usr/local/lib/libinotifytools.so.0 /usr/lib64/libinotifytools.so.0
rsync -avzP root@192.168.8.169::source-code /data/test/

169开发环境
166负载均衡服务器
167 web服务器1
168 web服务器2
169 修改代码同步到167和168上。
169作为rsync客户端,
167和168作为rsync服务端,
服务端配置(即167和168的配置):
(1)服务安装
yum install rsync xinetd
(2)为 rsyncd 服务编辑配置文件,默认没有,需自己编辑
vim /etc/rsyncd.conf
写入以下内容:
uid = root
gid = root
use chroot = no
max connections = 5
timeout = 600
pid file = /var/run/rsyncd.pid
lockfile = /var/run/rsyncd.lock
log file = /var/log/rsyncd.log
[web1]
path = /usr/local/nginx/html/hello/
ignore errors = yes
read only = no
write only = no
hosts allow = 192.168.8.169
hosts deny = *
list = yes
auth users = web
secrets file = /etc/web.passwd
(3)创建文件同步的目录,上面配置里的path,如果有就不用创建了
mkdir /usr/local/nginx/html/hello/
(4)创建配置中的密码文件,并增加权限:
echo “web:123” > /etc/web.passwd
chmod 600 /etc/web.passwd
(5)重新启动
service xinetd restart
客户端配置(即169):
(1)安装软件
yum -y install rsync
(2)创建web目录
mkdir /usr/local/nginx/html/hello/
(3)设置密码并设置权限
echo “123”> /tmp/rsync.password
chmod 600 /tmp/rsync.password
测试:
rsync -avzP –delete –password-file=/tmp/rsync.password /usr/local/nginx/html/hello/ web@192.168.8.167::web1
数据实时同步
环境:Rsync + Inotify-tools。
wget https://jaist.dl.sourceforge.net/project/inotify-tools/inotify-tools/3.13/inotify-tools-3.13.tar.gz
tar -zxvf inotify-tools-3.13.tar.gz
mkdir /usr/local/inotify
cd inotify-tools-3.13
./configure –prefix=/usr/local/inotify/
make && make install
设置环境变量
# vim /root/.bash_profile
export PATH=/usr/local/inotify/bin/:$PATH
# source /root/.bash_profile
# echo ‘/usr/local/inotify/lib’ >> /etc/ld.so.conf –加载库文件
# ldconfig
# ln -s /usr/local/inotify/include /usr/include/inotify
vim /etc/profile
在末尾增加一行:
export PATH=$PATH:/usr/local/inotify/bin
使配置生效:
source /etc/profile
创建shell文件:
vim /test.sh
输入以下内容:
#!/bin/bash
src=/usr/local/nginx/html/hello/
user=web
host1=192.168.8.167
dst1=web1
passpath=/tmp/rsync.password
/usr/local/inotify/bin/inotifywait \
-mrq –timefmt ‘%d/%m/%y’ \
–format ‘%T %w%f%e’ \
-e modify,delete,create,attrib \
/usr/local/nginx/html/hello/ | while read files
do
rsync -vzrtopg –delete –progress –passfile=$passfile-path $src $user@$host1::$dst1
echo “${files} was rsyncd” >>/tmp/rsync.log 2>&1
done
chmod 755 /data/test/test.sh
# /data/test/test.sh &
# echo ‘/data/test/test.sh &’ >> /etc/rc.local –设置开机自启
