Solo 开发指南

跑起来以后看文档 https://hacpai.com/article/1537690756242?r=88250

 org.xml.sax.SAXParseException; systemId: file:/usr/local/apache-tomcat-9.0.14/webapps/solo/META-INF/context.xml; lineNumber: 3; columnNumber: 1; Premature end of file.
​

这个文件有点问题，你看下是不是有损坏之类的。

安装并启动了 mysql 后，接下来修改 root@localhost 密码为 12345

mysql 在安装后会创建一个 root@locahost 账户(这是 mysql 本地登录的账号。MySQL8.0 为远程连接 root@% 和本地连接 root@locahost 提供了不同的密码验证方式。)，并且把本地连接初始的密码放到了/var/log/mysqld.log 文件中；用 cat /var/log/mysqld.log | grep password 命令查看初始密码。

[root@VM_0_11_centos solo]# cat /var/log/mysqld.log | grep password


2019-06-23T03:35:57.941668Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: n=Ti,P4?J(uE
​

注：上面 n=Ti,P4?J(uE 就是初始密码。

使用初始密码登录 mysql

[root@VM_0_11_centos solo]# mysql -uroot -p


Enter password:

mysql 的 root 用户的验证方式变了。从下面命令结果可以看出 root 的用户的加密方式为 caching_sha2_passoword,而 navicat 连接所用的方式为 native_password。

mysql> use mysql

下面开始修改密码操作，但是直接用 alter 命令改还不行，因为 123456 密太简单，不满足密码策略，查看密码策略命令如下：

mysql> SHOW VARIABLES LIKE 'validate%';

+--------------------------------------+--------+

| Variable_name                        | Value  |
+--------------------------------------+--------+
| validate_password.check_user_name    | ON     |
| validate_password.dictionary_file    |        |
| validate_password.length             | 8      |
| validate_password.mixed_case_count   | 1      |
| validate_password.number_count       | 1      |
| validate_password.policy             | MEDIUM |
| validate_password.special_char_count | 1      |
+--------------------------------------+--------+
7 rows in set (0.01 sec)
​

需要把 validate_password.check_user_name 改为 OFF，validate_password.length 改为 1，validate_password.policy 改为 LOW。命令如下：

mysql> set global validate_password.check_user_name=0;
Query OK, 0 rows affected (0.00 sec)

mysql> set global validate_password.length=1;
Query OK, 0 rows affected (0.00 sec)

mysql> set global validate_password.policy=0;
Query OK, 0 rows affected (0.00 sec)

mysql> SHOW VARIABLES LIKE 'validate%';

+--------------------------------------+-------+
| Variable_name                        | Value |
+--------------------------------------+-------+
| validate_password.check_user_name    | OFF   |
| validate_password.dictionary_file    |       |
| validate_password.length             | 4     |
| validate_password.mixed_case_count   | 1     |
| validate_password.number_count       | 1     |
| validate_password.policy             | LOW   |
| validate_password.special_char_count | 1     |
+--------------------------------------+-------+
7 rows in set (0.00 sec)

​

然后才可以开始改密码了：（本地和远程的都改为 123456）

mysql> alter user'root'@'localhost' IDENTIFIED BY '123456';
Query OK, 0 rows affected (0.01 sec)

mysql> ALTER USER 'root'@'%' IDENTIFIED by '123456';
Query OK, 0 rows affected (0.01 sec)

mysql> ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
