TrinityCore多区realms配置-do multiple realms for TrinityCore
TrinityCore是支持多区配置的，即多个realm分区。只需要起一套authserver服务，负责全部区的登录。需要在mysql的auth库中加入其它realm的配置信息，如：
+----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ | 1 | Trinity | 114.115.136.249 | 127.0.0.1 | 255.255.255.0 | 8085 | 0 | 0 | 16 | 0 | 0 | 12340 | | 2 | NewRealm | 114.115.136.249 | 127.0.0.1 | 255.255.255.0 | 8086 | 0 | 2 | 16 | 0 | 0 | 12340 | +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ 其它realms区只需要启动worldserver服务，不需要再启动authserver服务。worldserver.conf配置文件里需要mysql指向authserver的ip，如：LoginDatabaseInfo = "192.168.1.2;3306;trinity;trinity;auth" 。这里的192.168.1.2是authserver服务器的ip地址，也就是mysql的auth库是调用的authserver的内容，而character和world数据库，还是用各个realms本地的。

尝试TrinityCore多区配置
# 进入wow用户 su - wow # 进入mysql控制台 sudo mysql添加一条新区数据到realmlist
默认只有id 1,后来加了id 2 和6 两条。
mysql> insert into realmlist (name) values("test") ; Query OK, 1 row affected (0.01 sec) mysql> select * from realmlist; +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ | id | name | address | localAddress | localSubnetMask | port | icon | flag | timezone | allowedSecurityLevel | population | gamebuild | +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ | 1 | Trinity | 114.115.136.249 | 127.0.0.1 | 255.255.255.0 | 8085 | 0 | 0 | 1 | 0 | 0 | 12340 | | 2 | NewRealm | 192.168.1.12 | 127.0.0.1 | 255.255.255.0 | 8085 | 0 | 0 | 1 | 0 | 0 | 12340 | | 6 | test | 127.0.0.1 | 127.0.0.1 | 255.255.255.0 | 8085 | 0 | 2 | 0 | 0 | 0 | 12340 | +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ 3 rows in set (0.00 sec) 修改realm把realm id由3改为2
首先看一下：
mysql> use auth;
mysql> select id,name,address,localaddress,gamebuild from realmlist;
+----+----------+-----------------+--------------+-----------+
| id | name | address | localaddress | gamebuild |
+----+----------+-----------------+--------------+-----------+
| 1 | Trinity | 114.115.136.249 | 192.168.0.12 | 12340 |
| 3 | NewRealm | 192.168.1.12 | 192.168.1.12 | 12345 |
+----+----------+-----------------+--------------+-----------+
2 rows in set (0.00 sec)
把realm名字改成：NewRealm 。当然可以改成自己喜欢的名字。
刚开始拿到的id是3,把RealmID 从3改成2：
mysql> update realmlist set id="2" where id="3"; Query OK, 1 row affected (0.01 sec) Rows matched: 1 Changed: 1 Warnings: 0 worldserver.conf文件中修改
修改realm2区服务器的server/etc/worldserver.conf文件，把原文件中RealmID = 1 改为RealmID = 2
同样在authserver.conf文件中需要写
当时是这样的：
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 * from realmlist; +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ | id | name | address | localAddress | localSubnetMask | port | icon | flag | timezone | allowedSecurityLevel | population | gamebuild | +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ | 1 | Trinity | 114.115.136.249 | 192.168.0.12 | 255.255.255.0 | 8085 | 0 | 0 | 1 | 0 | 0 | 12340 | | 3 | NewRealm | 192.168.1.12 | 192.168.1.12 | 255.255.255.0 | 8085 | 0 | 0 | 0 | 0 | 0 | 12345 | +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ 2 rows in set (0.00 sec) 修改时区到16
timezone displayed name timezone displayed name 1 Development 20 CN4 2 United States 21 CN5 3 Oceanic 22 CN6 4 Latin America 23 CN7 5 Tournament 24 CN8 6 Korea 25 Tournament 7 Tournament 26 Test Server 8 English 27 Tournament 9 German 28 QA Server 10 French 29 CN9 11 Spanish 30 Test Server 2 12 Russian 31 CN10 13 Tournament 32 CTC 14 Taiwan 33 CNC 15 Tournament 34 CN1/4 16 China 35 CN2/6/9 17 CN1 36 CN3/7 18 CN2 37 CN5/8 19 CN3 把时区修改成16 中国
mysql> UPDATE realmlist SET timezone='16' WHERE id =3 ; Query OK, 1 row affected (0.03 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> UPDATE realmlist SET timezone='16' WHERE id =1 ; Query OK, 1 row affected (0.02 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> select * from realmlist; +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ | id | name | address | localAddress | localSubnetMask | port | icon | flag | timezone | allowedSecurityLevel | population | gamebuild | +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ | 1 | Trinity | 114.115.136.249 | 192.168.0.12 | 255.255.255.0 | 8085 | 0 | 0 | 16 | 0 | 0 | 12340 | | 3 | NewRealm | 192.168.1.12 | 192.168.1.12 | 255.255.255.0 | 8085 | 0 | 0 | 16 | 0 | 0 | 12345 | +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ 2 rows in set (0.01 sec) 但是现在登录到192.168.0.12,还是看不到多区。
现在总结一下，需要id 修改一下，比如把id改成2 ，同时worldserver.conf 文件里的 realmID 也设置为2
同时localAddress 不能用本地ip地址，如192.168.0.12 ，因为这样远端（通过公网）就无法连上服务器了。
解决看不到TrinityCore多区的问题
原来是版本的问题，以前用的版本是12340,后来编译的时候可能拿到的是12345,就是版本不一致导致客户端一直没有看见新区
mysql> update realmlist set gamebuild="12340" where id="2"; +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ | 1 | Trinity | 114.115.136.249 | 127.0.0.1 | 255.255.255.0 | 8085 | 0 | 0 | 16 | 0 | 0 | 12340 | | 2 | NewRealm | 192.168.1.12 | 127.0.0.1 | 255.255.255.0 | 8085 | 0 | 0 | 16 | 0 | 0 | 12340 | +----+----------+-----------------+--------------+-----------------+------+------
将RealmID改成1和2,将版本号都改成12340,现在终于能看到两个区了。
现在的问题是，如果账户登录的是1号realm（192.168.0.12），能看见两个区，但是只能登录1号区，登录2号区提示auth认证失败，进不去看见账户那里。
如果帐号登录的就是2号realm（192.168.1.12），那么登录1号区会失败，2号可以登录。
也就是无法1号和2号两个区同时登录成功。
核心：解决全网可通mysql auth数据库的问题
现在的核心就是要设置一个公用的mysql的auth库，并保证可以通过网络能连上这个库。
决定使用192.168.0.12为公用auth库，realm1 和realm2都指向这台服务器的mysql数据库。为了能够外网访问mysql，增加了一个host为%的语句：
mysql> use mysql 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> update auth set host = '%' where user = 'trinity'; ERROR 1146 (42S02): Table 'mysql.auth' doesn't exist mysql> update user set host = '%' where user = 'trinity'; Query OK, 1 row affected (0.01 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> select host, user from user; +-----------+------------------+ | host | user | +-----------+------------------+ | % | trinity | | localhost | debian-sys-maint | | localhost | mysql.infoschema | | localhost | mysql.session | | localhost | mysql.sys | | localhost | root | +-----------+------------------+ 6 rows in set (0.00 sec)现在调试，从192.168.1.12登过来，显示
Error: (1130, "Host '192.168.1.12' is not allowed to connect to this MySQL server")
发现是给错服务器了.....因为两台服务器，老是弄混.....
给192.168.0.12增加源ip192.168.1.12的登入权限：
CREATE USER 'trinity'@'192.168.1.12' IDENTIFIED BY 'trinity'; GRANT ALL PRIVILEGES ON auth.* TO 'trinity'@'192.168.1.12' WITH GRANT OPTION;可以看到加进去了：
select host, user from user; +--------------+------------------+ | host | user | +--------------+------------------+ | 192.168.1.12 | trinity | | localhost | debian-sys-maint | | localhost | mysql.infoschema | | localhost | mysql.session | | localhost | mysql.sys | | localhost | phpmyadmin | | localhost | root | | localhost | trinity | +--------------+------------------+ 9 rows in set (0.00 sec) 再配好worldserver的配置
worldserver从网上过来，如果是本地登录，设为本地192.168.1.12地址即可。
这里用了公网的ip的映射，最终auth realmlist的配置：
mysql> update realmlist set address="114.115.136.249" where id="2"; Query OK, 1 row affected (0.03 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> update realmlist set port="8086" where id="2"; Query OK, 1 row affected (0.02 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> update realmlist set timezone="16" where id="2"; Query OK, 1 row affected (0.04 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> select * ; ERROR 1096 (HY000): No tables used mysql> select * from auth; ERROR 1146 (42S02): Table 'auth.auth' doesn't exist mysql> select * from realmlist; +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ | id | name | address | localAddress | localSubnetMask | port | icon | flag | timezone | allowedSecurityLevel | population | gamebuild | +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ | 1 | Trinity | 114.115.136.249 | 127.0.0.1 | 255.255.255.0 | 8085 | 0 | 0 | 16 | 0 | 0 | 12340 | | 2 | NewRealm | 114.115.136.249 | 127.0.0.1 | 255.255.255.0 | 8086 | 0 | 2 | 16 | 0 | 0 | 12340 | +----+----------+-----------------+--------------+-----------------+------+------+------+----------+----------------------+------------+-----------+ 2 rows in set (0.00 sec) 这样终于多区配置成功了！两个区 Trinity和NewRealm都可以登录了！
总结
TrinityCore多区拓扑：
可以看到两个分区是不同网段，192.168.0.12和192.168.1.12且中间有一层NAT。内网的192.168.0.12被NAT为192.168.1.2 。
其实这不是必须的，在同一网段，或者不在同一网段，都可以实现TrinityCore的多区设置。当然有一个条件，就是其它的ream需要能够跟auth服务器的mysql通信，因为其它realm都是登入auth所在的mysql数据库并调用的其中的auth库内容。
对于所有的realms，都要设定auth指向192.168.0.12即worldserver.conf文件中设置，即多个realm认证服务用同一个数据库：
# LoginDatabaseInfo = "127.0.0.1;3306;trinity;trinity;auth" LoginDatabaseInfo = "192.168.1.2;3306;trinity;trinity;auth" 这里192.168.0.12数据库被NAT为192.168.1.2：3306 。所以最终指向了192.168.1.2 ，注意需要设置mysql支持网络登录，具体见：https://skywalk.blog.csdn.net/article/details/140786611
当然realm1 还是使用127.0.0.1地址登录myql，即：
LoginDatabaseInfo = "127.0.0.1;3306;trinity;trinity;auth"对于realmid，每个realm对需要跟auth数据库中的id值对应，比如这里
192.168.0.12 是realm 1, worldserver.conf中设为RealmID = 1：
192.168.1.12是realm2 ，设为RealmID = 2
如果再增加ream，则id依次增加即可。
worldserver.conf中RealmZone 是realm的分区，设为16即为cn ，默认是RealmZone = 1
最后注意gamebuild需要与客户端版本一致，否则客户端是看不到服务器的。
这样设置好后，TrinityCore多区realms就设定好了。当前还不支持跨服副本（Cross realms are not supported.）
