MySQL scheduled incremental backup rsync+crontab (enterprise combat)

1. Structure description
In order to prevent data loss caused by the failure of enterprise MySQL, this structure is derived

2. Environmental preparation
Two centos7
192.168.59.143 (server that needs backup)
192.168.59.144 (backup storage server)

Three, two install rsync service

yum -y install rsync

4. Modify the rsync configuration file of the server that needs to be backed up (192.168.59.143)

vim /etc/rsyncd.conf

添加如下配置
uid = root
gid = root
use chroot = no
max connections = 2
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
[app]           #模块
path = /data/   #备份路径
ignore errors
read only = false
list = false
auth users = backup
secrets file = /etc/rsync.passwd

Edit the password file and grant permissions (both of them are required)

echo "rsync_user:rsync_user_pwd" > /etc/rsync.password
chmod -R 600 /etc/rsync.password

Five, start rsync
1. Solve the error and not start

yum -y install xinetd
vim  /etc/xinetd.d/rsync

service rsync
{
    
    
disable = no
flags = IPv6
socket_type = stream
wait = no
user = root
server = /usr/bin/rsync
server_args = --daemon
log_on_failure += USERID
}

systemctl restart xinetd

Six, write a mission plan

crontab -e

Write the following commands into the script

/usr/bin/rsync -vzrtopg  --progress --password-file=/etc/rsync.passwd backup@192.168.59.143::app /data/

Seven, write incremental scripts
