新安装mysql第三方工具连接不上问题_MySQL
Mysql从客户端连接服务器连不上的问题
公司要用Mysql做一个测试,开始在自己的本地建一个Mysql数据库自己本地的程序再连上去,没有遇到过连接不上的问题。
这次数据库在服务器上,从本地客户端连接就是被拒绝。
报的错误为
ERROR 1130: Host ’192.168.5.3’ is not allowed to connect to this MySQL server

查过资料后发现这个问题,一般都会遇到,Mysql数据库跟其他数据库不一样,需要设置权限可以控制哪台机器能访问数据库,能访问哪些表。
所以就要登上服务器。
C:\Documents and Settings\Administrator>mysql -h localhost -u root -p
Enter password: ***
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 5
Server version: 5.1.43-community MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> grant all privileges on *.* to root@'%' identified by '123' with grant
-> option;
Query OK, 0 rows affected (0.00 sec)
意思就是将服务器上的所有资源都给root用户权限,%代表来自不同的IP
这里需要注意一下要把密码也要带上。通过密码123登录。
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
最后要刷新下权限。
这样就从本地192.168.5.3这个IP的客户端连接到服务器上了

To improve the performance of DebianHadoop cluster, we need to start from hardware, software, resource management and performance tuning. The following are some key optimization strategies and suggestions: 1. Select hardware and system configurations carefully to select hardware configurations: Select the appropriate CPU, memory and storage devices according to actual application scenarios. SSD accelerated I/O: Use solid state hard drives (SSDs) as much as possible to improve I/O operation speed. Memory expansion: Allocate sufficient memory to NameNode and DataNode nodes to cope with larger data processing and tasks. 2. Software configuration optimization Hadoop configuration file adjustment: core-site.xml: Configure HDFS default file system

This article describes how to optimize ZooKeeper performance on Debian systems. We will provide advice on hardware, operating system, ZooKeeper configuration and monitoring. 1. Optimize storage media upgrade at the system level: Replacing traditional mechanical hard drives with SSD solid-state drives will significantly improve I/O performance and reduce access latency. Disable swap partitioning: By adjusting kernel parameters, reduce dependence on swap partitions and avoid performance losses caused by frequent memory and disk swaps. Improve file descriptor upper limit: Increase the number of file descriptors allowed to be opened at the same time by the system to avoid resource limitations affecting the processing efficiency of ZooKeeper. 2. ZooKeeper configuration optimization zoo.cfg file configuration

The network configuration of the Debian system is mainly implemented through the /etc/network/interfaces file, which defines network interface parameters, such as IP address, gateway, and DNS server. Debian systems usually use ifup and ifdown commands to start and stop network interfaces. By modifying the ifeline in the interfaces file, you can set a static IP or use DHCP to dynamically obtain the IP address. It should be noted that Debian12 and subsequent versions no longer use NetworkManager by default, so other command-line tools, such as IP commands, may be required to manage network interfaces. You can edit /etc/netwo

To strengthen the security of Oracle database on the Debian system, it requires many aspects to start. The following steps provide a framework for secure configuration: 1. Oracle database installation and initial configuration system preparation: Ensure that the Debian system has been updated to the latest version, the network configuration is correct, and all required software packages are installed. It is recommended to refer to official documents or reliable third-party resources for installation. Users and Groups: Create a dedicated Oracle user group (such as oinstall, dba, backupdba) and set appropriate permissions for it. 2. Security restrictions set resource restrictions: Edit /etc/security/limits.d/30-oracle.conf

Mastering Debian system log monitoring is the key to efficient operation and maintenance. It can help you understand the system's operating conditions in a timely manner, quickly locate faults, and optimize system performance. This article will introduce several commonly used monitoring methods and tools. Monitoring system resources with the sysstat toolkit The sysstat toolkit provides a series of powerful command line tools for collecting, analyzing and reporting various system resource metrics, including CPU load, memory usage, disk I/O, network throughput, etc. The main tools include: sar: a comprehensive system resource statistics tool, covering CPU, memory, disk, network, etc. iostat: disk and CPU statistics. mpstat: Statistics of multi-core CPUs. pidsta

Experience the convenience of Flutter hot reloading on the Debian system, just follow the steps below: Install FlutterSDK: First, you need to install FlutterSDK on the Debian system. Visit Flutter official website to download the latest stable version of SDK and decompress to the specified directory (for example, ~/flutter). After that, add Flutter's bin directory to the system PATH environment variable. Edit the ~/.bashrc or ~/.profile file, add the following code: exportPATH="$PATH:~/flutter/bin" Save the file and execute source~/.bas

Syslog for Debian systems is a key tool for system administrators to diagnose problems. This article provides some steps and commands to troubleshoot common Syslog problems: 1. Log viewing real-time viewing of the latest log: tail-f/var/log/syslog viewing kernel logs (start errors and driver problems): dmesg uses journalctl (Debian8 and above, systemd system): journalctl-b (viewing after startup logs), journalctl-f (viewing new logs in real-time). 2. System resource monitoring and viewing process and resource usage: psaux (find high resource occupancy process) real-time monitoring
