2016-04-13T02:46:03.137034Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
2016-04-13T02:46:03.201517Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: dcd726b9-0121-11e6-9763-525400b32df6.
2016-04-13T02:46:03.202687Z 0 [Warning] Gtid table is not ready to be used. Table ‘mysql.gtid_executed‘ cannot be opened.
2016-04-13T02:46:03.203686Z 1 [Note] A temporary password is generated for root@localhost: IWse#l?eh6#1

--------------------------------------
启动数据库
cd /www/wdlinux/init.d
./mysqld start
Starting MySQL. SUCCESS!

---------------------------------------
修改root密码
mysqladmin -u root -p"IWse#l?eh6#1" password "Bgichina1&test"

mysqladmin: [Warning] Using a password on the command line interface can be insecure.
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.
---------------------------------------
还原数据库
mysql -uroot -p"Bgichina1&test"
create database db_wegram;
create database wdcpdb;

mysql -uroot -p"Bgichina1&test" db_wegram < db_wegram_test.dump
mysql -uroot -p"Bgichina1&test" wdcpdb < wdcpdb_test.dump

-----------------------------------------
修改表的charset
alter table chat_message CHARSET=utf8mb4;
alter table chat_message CHANGE content content VARCHAR(2048) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

-----------------------------------------
解决“无法连接mysql，请检查mysql是否已启动及用户密码是否设置正确!:”的问题
在phpmyadmin里添加用户wdcp@localhost
点击localhost>>wdcpdb>>点右侧的人行图标，提示“检查数据库wdcpdb的权限”
点下方的“添加新用户”按钮
密码输入abcd1234
用户数据库的选项选择“授予数据库“wdcpdb”的所有权限。”，然后保存
密码还可以修改的

然后cd /www/wdlinux/wdcp/data
vim db.inc.php
$dbuser=‘wdcp‘;
$dbpw=‘abcd1234‘;
保存就可以了,注意如果注释行的话用//而不是#，不然有可能会让wdcp面板出现白板
