2、搭建Mysql主服务器
# mysql-master:（提前脚本安装好mysql）
[root@mysql-master ~]#vim /etc/my.cnf #更改配置文件
[mysqld]
server-id=104
log-bin
datadir=/data/mysql
socket=/data/mysql/mysql.sock
log-error=/data/mysql/mysql.log
pid-file=/data/mysql/mysql.pid
default_authentication_plugin=mysql_native_password
gtid_mode=ON
enforce_gtid_consistency
[client]
socket=/data/mysql/mysql.sock
[root@mysql-master ~]#systemctl restart mysql
[root@mysql-master ~]#mysql -p123456
mysql> create user repluser@'10.0.0.%' identified by '123456'; #创建主从同步账号并授权
mysql> grant replication slave on *.* to repluser@'10.0.0.%';
mysql> create user shopxo@'10.0.0.%' identified by '123456'; #创建主从同步账号并授权
mysql> grant all on shopxo.* to shopxo@'10.0.0.%';
3、搭建Mysql从服务器
# mysql-slave： （提前脚本安装好mysql）
[root@ubuntu2004 ~]#vim /etc/my.cnf
[mysqld]
server-id=104
log-bin
datadir=/data/mysql
socket=/data/mysql/mysql.sock
log-error=/data/mysql/mysql.log
pid-file=/data/mysql/mysql.pid
default_authentication_plugin=mysql_native_password
gtid_mode=ON
enforce_gtid_consistency
[client]
socket=/data/mysql/mysql.sock
[root@ubuntu2004 ~]#systemctl restart mysql
[root@ubuntu2004 ~]#mysql -p123456
CHANGE MASTER TO
MASTER_HOST='10.0.0.103',
MASTER_USER='repluser',
MASTER_PASSWORD='123456',
MASTER_PORT=3306,
MASTER_AUTO_POSITION=1;
mysql> start slave;
4、搭建nfs-backup服务器
## nfs-backup：
[root@nfs-backup ~]#apt install -y rsync
[root@nfs-backup ~]#vim /etc/rsyncd.conf
uid = root
gid = root
max connections = 0
ignore errors
exclude = lost+found/
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock
reverse lookup = no
[backup]
path = /data/backup/
comment = backup dir
read only = no
auth users = rsyncuser
secrets file = /etc/rsync.pas
[root@nfs-backup ~]#echo rsyncuser:123456 > /etc/rsync.pas
[root@nfs-backup ~]#chmod 600 /etc/rsync.pas
[root@nfs-backup ~]#mkdir /data/backup -p
[root@nfs-backup ~]#setfacl -m u:nobody:rwx /data/backup
[root@nfs-backup ~]#systemctl restart rsync.service
# 105服务器nfs-data验证：
[root@nfs-data ~]#rsync rsyncuser@10.0.0.106::backup
Password:
drwxr-xr-x 4,096 2022/09/07 20:18:38 .

@ IN SOA wang rname.invalid. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS wang
wang A 192.168.10.100
www A 192.168.0.100
10、客户机测试
[root@client ~]# vim /etc/resolv.conf #指向dns服务器
nameserver 192.168.10.100
[root@client ~]# curl www.dayu.org #测试
