配置jpress，需要war包，本文用的jpress-v3.2.4.war，

v3.2.4war包在網盤中連結：https://pan.baidu.com/s/1toHMzutkkQQp3ULMsIVuxg 提取碼：0ej2

其他版本mysql8.0 、jdk1.8

出現過的問題：

1、jpress安裝失敗----提示連線資料庫失敗 eq: 更換jpress版本為v3.2.4

2、mysql授權問題----上面程式碼中已經寫明具體，

3、mysql ------Can't connect to local MySQL server through socket '/storage/db/mysql/mysql.sock

　　eq:修改my.cnf檔案：

　　　　在/etc/my.cnf檔案中新增如下內容，並重啟mysqls服務，即可解決mysql,mysqldump,mysqladmin的“Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'”問題：注意socket對應的是你本地存放mysql.sock地址，找不到就用 find name 'mysql.sock'查

[mysqld]
datadir=/storage/db/mysql
socket=/storage/db/mysql/mysql.sock

[mysql]
socket=/storage/db/mysql/mysql.sock

[client]
socket=/storage/db/mysql/mysql.sock

[mysqldump]
socket=/storage/db/mysql/mysql.sock

[mysqladmin]
socket=/storage/db/mysql/mysql.sock

　4、Navicat連線不到資料庫------被第3個問題影響，解決3，重啟mysql服務，
