WDCP控制面板升级mysql为5.7.11的方法
1、下载解压
下载地址为：dev.mysql/get/Downloads/MySQL-5.7/mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz
tar -xvf mysql-5.7.11-linux-glibc2.5-x86_64.tar
得到mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz mysql-test-5.7.11-linux-glibc2.5-x86_64.tar.gz
tar -zxvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz
tar -zxvf mysql-test-5.7.11-linux-glibc2.5-x86_64.tar.gz
------------------------
2、备份
mysqldump -uroot -p"Bgichina1&test" db_wegram > db_wegram_test.dump
mysqldump -uroot -p"Bgichina1&test" wdcpdb > wdcpdb_test.dump
-------------------------------------------
ps -ax | grep mysql

--------------------------------------
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
