首先，遇到此问题的一些必要条件：         1.在Windows环境下开发GTK+程序         2.使用Glade3辅助开发GTK+程序         3.使用GtkBuilder对象读取XML文件的程序 其次，和此问题无关的东东：（相信看到此篇文章的不少同学，肯定GOOGLE了不短时间）           1.gcc使用-export-dynamic

当每进行n次事务提交之后，MySQL将进行一次fsync之类的磁盘同步指令来将binlog_cache中的数据强制写入磁盘。如果slave_pending_jobs_size_max的大小小于当前需要执行事件所需的内存大小。1、调大slave_pending_jobs_size_max。sas硬盘建议200，如果是nvme固态盘，建议调整为1500。在arm服务器里运行MySQL5.7.22版本。调整并行复制的参数，建议修改为cpu的核数。属于漏洞，已经在新版本里修复了。

dbus-glib是dbus底层接口的一个封装。本讲我们用dbus-glib做一个dus接口，并写一个客户程序。 1、接口描述文件 首先编写接口描述文件.我们要实现的连接的公共名是"org.freedesktop.messagetestcuiyf"，接口描述文件如下： $cat messagetest.xml <?xml version="1.0" encoding="UTF-8" ?> <node name="/org/freedesktop/MessageTest/De

其实我在当前内网环境验证过很多方法了，都没有结果，后面实再没办法后我在本地安装了一个centos7.2版本的镜像，有外网的环境中折腾了下，错误过程也就不展示了，最终怎么弄都不行我就想着升级docker版本到最新或者降低版本（因为7.6的环境没问题，7.2和7.0环境出问题了），我想着先降低版本试下，然后发现，降低版本后，欸，可以了。之前20.10的docker只有9个包，现在19.03有28个包，26.1.4有34个包，额。对了，如果下载后不会使用，参考说明中的docker离线安装哈。
