备份和镜像TrinityCore

相比重新安装，省去了编译的过程，同时还能保留以前的人物、装备等。

注意，若不想重新编译安装，则需要创建一样的目录、账户等，以减少不必要的麻烦。

首先备份数据:

备份文件

sql 复制代码

mysqldump -u trinity -ptrinity auth > auth.sql
 
mysqldump -u trinity -ptrinity world > world.sql
 
mysqldump -u trinity -ptrinity characters > characters.sql

备份的时候会有警告和报错：'Access denied; you need (at least one of) the PROCESS privilege(s) for this operation' ，不用去管它。

将备份文件scp到服务器：

sql 复制代码

scp *.sql 192.168.1.12:/home/wow

准备导入数据库。

数据库导入

导入之前，需要导入一个"创建数据库"的sql

只需要导入这一个，后面其它数据库会自动导入

To create the MySQL databases needed by Trinity, you need to execute one of the following MySQL queries with your mysql client:

For 3.3.x:
- TrinityCore/sql/create/create_mysql.sql at 3.3.5 · TrinityCore/TrinityCore · GitHub

或者到项目TrinityCore/sql/create目录也能获取该文件，该文件内容：

CREATE USER 'trinity'@'localhost' IDENTIFIED BY 'trinity' WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0;

GRANT USAGE ON * . * TO 'trinity'@'localhost';

CREATE DATABASE `world` DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

CREATE DATABASE `characters` DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

CREATE DATABASE `auth` DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

GRANT ALL PRIVILEGES ON `world` . * TO 'trinity'@'localhost' WITH GRANT OPTION;

GRANT ALL PRIVILEGES ON `characters` . * TO 'trinity'@'localhost' WITH GRANT OPTION;

GRANT ALL PRIVILEGES ON `auth` . * TO 'trinity'@'localhost' WITH GRANT OPTION;

下载之后，进入mysql，然后导入：

source  create_mysql.sql

这时候一套新的TrinityCore服务已经安装好了。如果这时候执行下一步同步TrinityCore文件并启动authserver和worldserver，就是全新环境。启动之后再导入auth和characters两个库，理论上就能恢复当前游戏环境和账户等。但是因为加入了TrinityBot功能，所以world库也需要进行相应修改。最终就是三个库一起导入：

导入备份的三个文件：

sql 复制代码

sudo mysql
 
use auth;
 
source auth.sql
 
use world
 
source world.sql
 
use characters
 
source characters.sql

同步TrinityCore文件

直接把server目录全部cp到新机器的相同目录：

scp -r server 192.168.1.12:/home/wow/scp -R server 192.168.1.12:/home/wow/

修改服务器地址

因为换了机器，所以要修改auth里面的address地址，修改成192.168.1.12

sql 复制代码

mysql> use auth;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> select id,name,address,localaddress,gamebuild from realmlist;
+----+---------+-----------------+--------------+-----------+

1 row in set (0.01 sec)

mysql> UPDATE realmlist SET address = '192.168.1.12' WHERE address = '114.115.136.249';

mysql> select id,name,address,localaddress,gamebuild from realmlist;
+----+---------+--------------+--------------+-----------+

+----+---------+--------------+--------------+-----------+
|  1 | Trinity | 192.168.1.12 | 127.0.0.1    |     12340 |
+----+---------+--------------+--------------+-----------+
1 row in set (0.00 sec)

下载官方源码

启动server/bin/worldserver 之后报错：DBUpdater: The given source directory /home/wow/TrinityCore does not exist 。原来还是需要官方的源码，并要放在以前编译的时候的目录位置。也就是wow账户的TrinityCore目录。另外现在git clone默认拉下来的是wow最新版，我们采用的是3.3.5版本，这样git clone需要带上-b 3.3.5参数

sql 复制代码

git clone --depth 1 -b 3.3.5 https://github.com/TrinityCore/TrinityCore

好了，到了这里，服务器就完全镜像过来了！新的一台服务器就装好了。

这时候先执行server/bin/authserver ,然后再执行server/bin/worldserver ,整个服务就起来了！

调试

启动worldserver报错

Updating Auth database...

看了下：master = 10.2.7.55165, 3.3.5 = 3.3.5a.12340, wotlk_classic = 3.4.3.54261, cata classic = 4.4.0.55141

原来这是分支没弄对。

切换到3.3.5分支：

git checkout 3.3.5

没切成，重新git clone

sql 复制代码

git clone --depth 1 -b 3.3.5 https://github.com/TrinityCore/TrinityCore

发现延时异常大

演示472ms，这也太大了，怎么回事呢 ? 有的号延时1ms，真是弄不懂了...
