官方升级指导文件

Upgrading Cacti

Backup the old Cacti database.
```
shell> mysqldump -l --add-drop-table cacti > mysql.cacti
```
Note: You will probably have to specify the -u and -p flags for the MySQL username and password. This user must have permission to read from Cacti's database or you will end up with an empty backup.
备份数据库

Backup the old Cacti directory.

shell> mv cacti cacti_old

备份旧的版本

Extract the distribution tarball.

shell> tar xzvf cacti-version.tar.gz

解压程序包

Rename the new Cacti directory to match the old one.
```
shell> mv cacti-version cacti
```
```
重命名
```

Edit include/config.php and specify the MySQL user, password and database for your Cacti configuration.

$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cacti";

编辑配置文件

Copy the *.rrd files from the old Cacti directory.

shell> cp cacti_old/rra/* cacti/rra/

拷贝数据文件

Copy any relevant custom scripts from the old Cacti directory. Some script are updated between versions. Therefore, make sure you only over write if the scripts either don't exist or are newer than the distribution's.
```
shell> cp -u cacti_old/scripts/* cacti/scripts/
```
```
拷贝脚本
```
Copy any relevant custom resource XML files from the old Cacti directory. Some resource XML files are updated between versions. Therefore, make sure you only over write if the XML files either don't exist or are newer than the distribution's.
```
shell> cp -u -R cacti_old/resource/* cacti/resource/
拷贝xml文件
```
Set the appropriate permissions on Cacti's directories for graph/log generation. You should execute these commands from inside Cacti's directory to change the permissions.
```
shell> chown -R cactiuser rra/ log/
```
```
更改程序所有者
```
(Enter a valid username for cactiuser, this user will also be used in the next step for data gathering.)
Point your web browser to:
