较前一vsftpd安装脚本(yum安装)  改了本地用户验证方式,添加用户时不用再向chroot文件添加用户名

具体脚本如下:

#!/bin/bash

echo "--------------------------------vsftpd 自动安装脚本--------------------------------"
yum -y install vsftpd
sed -i 's#anonymous_enable=YES#anonymous_enable=NO#'  /etc/vsftpd/vsftpd.conf
sed -i 's\#ftpd_banner=Welcome to blah FTP service.\ftpd_banner=Welcome to my vsftpd FTP service.\g' /etc/vsftpd/vsftpd.conf
echo "chroot_local_user=YES" >>/etc/vsftpd/vsftpd.conf
mkdir -p /wwwroot/htdocs
groupadd www
useradd www -g www -d /wwwroot/htdocs -s /sbin/nologin
passwd www
chown www.www /wwwroot/htdocs
chkconfig vsftpd on
service vsftpd start
echo "--------------------------------vsftpd 安装说明------------------------------------"
echo "|                                                                                  |"
echo "|               用户为 www 密码为刚才所设 FTP根目录为/wwwroot/htdocs               |"
echo "| 新增用户样例为(新增用户ktm):useradd ktm -g www -d /wwwroot/ktm -s /sbin/nologin  |"
echo "|                              service vsftpd restart                              |"
echo "|                                                                                  |"
echo "--------------------------------vsftpd 安装结束!-----------------------------------"
sleep 2

特别说明:
配置mysql主从备份一定要使用相同版本的数据库,如不可以使用5.0和5.1的交杂.

1.主机
建任意主机用户,并赋于对指定数据库的相应权限,并开放3306端口的外网访问(防火墙),如添加的用户为admin,创建的数据库为test,如以下主机为linux
vi /etc/my.cnf
在[mysqld]段添加:
server-id       = 1
log-bin
重启mysql
查看状态:
mysql -u root -p
输入密码后,
show master status;
看到如下:
+-------------------+----------+--------------+------------------+
| File              | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+-------------------+----------+--------------+------------------+
| centos-bin.000001 |      106 |              |                  |
+-------------------+----------+--------------+------------------+
1 row in set (0.00 sec)

从服务器连接测试
比如主服务器IP为192.168.0.2
mysql -h 192.168.0.2 -u admin -p
能正常登录为成功


2.从服务器my.ini(如主机为win)
[mysqld]段添加:
server-id=2
master-host=192.168.0.2
master-port=3306
master-user=admin
master-password=123456
master-connect-retry=60
replicate-do-db=test

检查状态:
mysql -u root -p
show slave status\G;

看到
Slave_IO_Running:Yes
Slave_SQL_running:Yes
说明是成功的

这时候,可以在主机上安装程序,如安装Disucz,只要主机上的数据库发生了改变,都会自动备份到从服务器的数据库里

相关命令:
Slave start
Slave stop
Reset slave
Show slave status
Show master status
主服务器命令需登录主机执行,从命令登录从服务器运行,当然,在从服务器运行主机的mysql也可以,正如:
mysql -h 192.168.0.2 -u admin -p

自己写的一个简单的脚本，执行安装即可
