mysql5.7版本中如何禁止掉SSL功能，默认是开启的

哪位大神知道怎么关闭mysql的SSL功能，现在在5.7版本里面默认是开启的

在Win10系统下怎样才能正确配置MySQL5.7.20的SSL连接？

各位大佬，小弟现在遇到的问题是： 在win10系统中，为了数据库的安全，我需要配置MySQL的SSL连接，但是一直配置不成功， 所以想请教各位大佬，我该怎么样才能配置成功，谢谢！

php7 mysql5.7 打架啦

问题是这样的，全新Ubuntu14.04 （aliyun）里安装了mysql 5.7.13  然后下载编译的PHP7 ./configure 的参数为 --enable-ftp --enable-fpm --with-pdo-mysql=/usr/bin/mysql 提示成功生成Makefile。 继续make时则出现以下错误 ```

关于Ubuntu16.04用tar.gz通用压缩包安装mysql5.7.17失败

系统Ubuntu16.04 64位 准备安装MySQL 57.7.17 概要 apt-cache search libaio #安装mysql依赖库 tar -zxvf -zxvf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz #解压压缩包 mv mysql-5.7.17-linux-glibc2.5-x86_64 mysql #修改名字 groupadd mysql #添加用户组 useradd -r -g mysql -s /bin/false mysql #添加用户 cd mysql #进入mysql目录 mkdir mysql-files #新建目录 chmod 750 mysql-files #给目录授权为mysql 用户 chown -R mysql . chgrp -R mysql . bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data #初始化mysql数据库 bin/mysql_ssl_rsa_setup #创建SSL证书，密钥文件和RSA密钥对文件 chown -R root . #给当前目录授权为用户root chown -R mysql data mysql-files bin/mysqld_safe --user=mysql & #启动mysql 问题卡在这了  详细步骤 1.安装准备 1.1查看自己的Linux系统版本 命令： cat /etc/issue 再具体点：uname -a 86_64就代表64位的系统 OK，咱们确定了自己的系统，现在去MySQL官网下载二进制压缩包源文件 1.2官网下载安装包 https://dev.mysql.com/downloads/mysql/  选择对应的安装包   下载的话，有两种方式： 1.从官网下载，然后用FTP软件上传到服务器上。 2.使用在线下载的方式，使用命令： wget -P /usr/local/support https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz 注：-P /usr/local/support 是指定下载目录 不要问我为啥网速这么快。。。。我也震惊了  2.开始安装： 参考官方文档 ①为了预防以前安装过mysql，导致旧版本遗留文件冲突，所以需要把以前安装的文件都删除掉 /etc/my.cnf /etc/msyql目录 查找命令： find / -name 文件名or目录名 删除命令： rm -rf 文件名or目录名 ②安装mysql的依赖库libaio 搜索命令 apt-cache search libaio apt-cache search libaio 如果搜索没有显示结果，就安装 安装命令：apt-get install libaio1 注：如果报错，则需要使用更新命令 apt-get update 更新后就可以安装依赖库了 ③解压压缩包 命令： tar -zxvf -zxvf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz ④改名字，便于操作 命令：mv mysql-5.7.17-linux-glibc2.5-x86_64 mysql ④添加用户组， 添加用户 groupadd mysql useradd -r -g mysql -s /bin/false mysql ⑤进入msyql目录，创建目录mysql-files cd mysql mkdir mysql-files ⑥给文件夹授权为用户mysql chmod 750 mysql-files chown -R mysql . chgrp -R mysql . ⑦初始化数据库 bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data ⑧创建SSL证书，密钥文件和RSA密钥对文件 bin/mysql_ssl_rsa_setup ⑨给当前目录授权为用户root chown -R root . chown -R mysql data mysql-files ⑩问题来了 每当我执行到这个命令时，就卡那不懂了。。。。请教大神，这是为什么 bin/mysqld_safe --user=mysql & # Next command is optional  然后： 执行 mysql -u root -p 再输入密码，显示：  尝试解决 网上搜的方法： 在my.cnf 中添加sockt  使用该方法启动 mysql -p --socket=/tmp/mysql.sock  另外，参考这篇博客 http://ng2.site/mysql/2016/11/16/install-mysql-offline.html 也是安装失败，请大神指点！ ------------------------------------------------------------------------------------------------------------------------------------------------------ PS： 我用apt-get install mysql-server 可以成功安装，但是用通用二进制压缩包离线安装一直安装不成功，这个问题纠结我很久了，成了心结，所以一定要解决掉！

WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

Eclipse连接MySQL后运行正常，但出现了下述红色的字体，请问怎么解决这一问题？

Java学习的正确打开方式

在博主认为，对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结，前三者博主将淋漓尽致地挥毫于这篇博客文章中，至于总结在于个人，实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍，博客次之，这又是一个层次了，这里暂时不提后面再谈。博主将为各位入门java保驾护航，各位只管冲鸭！！！上天是公平的，只要不辜负时间，时间自然不会辜负你。 何谓学习？博主所理解的学习，它是一个过程，是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。

程序员必须掌握的核心算法有哪些？

程序员接私活怎样防止做完了不给钱？

首先跟大家说明一点，我们做 IT 类的外包开发，是非标品开发，所以很有可能在开发过程中会有这样那样的需求修改，而这种需求修改很容易造成扯皮，进而影响到费用支付，甚至出现做完了项目收不到钱的情况。 那么，怎么保证自己的薪酬安全呢？ 我们在开工前，一定要做好一些证据方面的准备（也就是“讨薪”的理论依据），这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...

Python实例大全（基于Python3.7.4）

博客说明： 这是自己写的有关python语言的一篇综合博客。 只作为知识广度和编程技巧学习，不过于追究学习深度，点到即止、会用即可。 主要是基础语句，如三大控制语句（顺序、分支、循环），随机数的生成，数据类型的区分和使用； 也会涉及常用的算法和数据结构，以及面试题相关经验； 主体部分是针对python的数据挖掘和数据分析，主要先攻爬虫方向：正则表达式匹配，常用数据清洗办法，scrapy及其他爬虫框架，数据存储方式及其实现； 最后还会粗略涉及人工智能领域，玩转大数据与云计算、进行相关的预测和分析。
