1.2 mysql控制台命令启动master模式
mysql>GRANT replication slave on *.* to 'slave2'@'10.0.0.2' IDENTIFIED BY 'password';
mysql>SHOW master status;
2 从机设置
2.1 从机配置
server-id = 2 log_bin = /var/log/mysql/mysql-bin.log expire_logs_days = 2 max_binlog_size = 100M
2.2 从机控制台命令
mysql>slave stop；
mysql>change master to master_host='10.0.0.1', master_port=3306, master_user='slave2', master_password='password', master_log_file='mysql-bin.000011', master_log_pos=189;

1 设置/etc/sysctl.conf
net.ipv4.io_forward=1;
2 iptables规则
sudo iptables -t nat -A POSTROUTING -s 10.0.1.0/24 -o wlan0 -j MASQUERADE
3 /etc/network/interfaces
auto eth0 iface eth0 inet static address 10.0.1.1 netmask 255.255.255.0
局域网上网机器设置
1 /etc/network/interfaces
auto eth0 iface eth0 inet static address 10.0.1.2 gateway 10.0.1.1 netmask 255.255.255.0 dns-nameservers 8.8.8.8
