This article mainly introduces the detailed explanation of CentOS6.8 installation FTP and adding users. The editor thinks it is quite good, so I will share it with you now and give it as a reference. Let’s follow the editor and take a look.
Install FTP
1 Check whether FTP has been installed
rpm -qa | grep vsftpd
2 If not, install it
yum install vsftpd
2 Set vsftpd to start at boot
chkconfig --level 35 vsftpd on
3 Configure the FTP server (turn on user-based Access control)
1 Modification of configuration file
vim /etc/vsftpd/vsftpd.conf
anonymous_enable=NO # 是否开启匿名登录 local_enable=YES # 是否允许本地用户登录 write_enable=YES # 是否允许上传 local_umask=022 # 默认的umask码 diremssage_enable=YES # 是否显示目录说明文件 xferlog_enable=YES # 是否记录ftp传输过程 connect_from_prot_20=YES # 是否确定端口传输来自20 xferlog_ftd_format=YES # 是否使用标准的ftp xferlog模式 chroot_list_enable=YES # 是否将系统用户限制在自己的home目录下 chroot_list_file=/etc/vsftpd/chroot_list # 列表不受限制的用户 listen=YES # 是否开启监听 pam_service_name=vsftpd # 服务名称 userlist_enable=YES tcp_wrappers=YES
2 Modification of selinux
getsebool -a | grep ftp
If an error is reported, getsebool: SELinux is disabled. Then
vim /etc/selinux/config
modify SELINUX=1.
Then restart LINUX, "shutdown -r now" to restart immediately (for root user).
Re-execute "getsebool -a | grep ftp".
Modify selinux to allow users to write data in the home directory
setsebool -P allow_ftpd_anon_write off setsebool -P ftp_home_dir on
4 Create a virtual user
1 Create a user, and then modify the user’s login shell For nologin, users cannot log in to the system and can only use services within ftp
useradd -d /home/www/test -g ftp -s /sbin/nologin test # 指定用户 test 属于组 ftp,只能访问的目录是 /home/www/test,不能登陆系统 passwd test # 设置该用户的密码
2 Add user test to chroot_list
vim /etc/vsftpd/chroot_list # 把 test 加入该文件
Five test virtual users
Enter "ftp://yourip" in the address bar of the browser, enter the account number and password in the pop-up dialog box, and the connection will be successful.
Six other configurations
Open the configuration file vsftpd.conf
max_client=100 # vsftpd最大支持链接数100个IP max_per=5 # 每个IP能支持5个链接 local_max_rate=81920 # 限制传输速度 listen_address=某个IP # 绑定某个IP到vsftpd,只允许该IP访问 xferlog_file=/var/log/vsftpd.log # 日志存放位置

The core components of Linux include the kernel, file system, shell and common tools. 1. The kernel manages hardware resources and provides basic services. 2. The file system organizes and stores data. 3. Shell is the interface for users to interact with the system. 4. Common tools help complete daily tasks.

The basic structure of Linux includes the kernel, file system, and shell. 1) Kernel management hardware resources and use uname-r to view the version. 2) The EXT4 file system supports large files and logs and is created using mkfs.ext4. 3) Shell provides command line interaction such as Bash, and lists files using ls-l.

The key steps in Linux system management and maintenance include: 1) Master the basic knowledge, such as file system structure and user management; 2) Carry out system monitoring and resource management, use top, htop and other tools; 3) Use system logs to troubleshoot, use journalctl and other tools; 4) Write automated scripts and task scheduling, use cron tools; 5) implement security management and protection, configure firewalls through iptables; 6) Carry out performance optimization and best practices, adjust kernel parameters and develop good habits.

Linux maintenance mode is entered by adding init=/bin/bash or single parameters at startup. 1. Enter maintenance mode: Edit the GRUB menu and add startup parameters. 2. Remount the file system to read and write mode: mount-oremount,rw/. 3. Repair the file system: Use the fsck command, such as fsck/dev/sda1. 4. Back up the data and operate with caution to avoid data loss.

This article discusses how to improve Hadoop data processing efficiency on Debian systems. Optimization strategies cover hardware upgrades, operating system parameter adjustments, Hadoop configuration modifications, and the use of efficient algorithms and tools. 1. Hardware resource strengthening ensures that all nodes have consistent hardware configurations, especially paying attention to CPU, memory and network equipment performance. Choosing high-performance hardware components is essential to improve overall processing speed. 2. Operating system tunes file descriptors and network connections: Modify the /etc/security/limits.conf file to increase the upper limit of file descriptors and network connections allowed to be opened at the same time by the system. JVM parameter adjustment: Adjust in hadoop-env.sh file

This guide will guide you to learn how to use Syslog in Debian systems. Syslog is a key service in Linux systems for logging system and application log messages. It helps administrators monitor and analyze system activity to quickly identify and resolve problems. 1. Basic knowledge of Syslog The core functions of Syslog include: centrally collecting and managing log messages; supporting multiple log output formats and target locations (such as files or networks); providing real-time log viewing and filtering functions. 2. Install and configure Syslog (using Rsyslog) The Debian system uses Rsyslog by default. You can install it with the following command: sudoaptupdatesud

When choosing a Hadoop version suitable for Debian system, the following key factors need to be considered: 1. Stability and long-term support: For users who pursue stability and security, it is recommended to choose a Debian stable version, such as Debian11 (Bullseye). This version has been fully tested and has a support cycle of up to five years, which can ensure the stable operation of the system. 2. Package update speed: If you need to use the latest Hadoop features and features, you can consider Debian's unstable version (Sid). However, it should be noted that unstable versions may have compatibility issues and stability risks. 3. Community support and resources: Debian has huge community support, which can provide rich documentation and

This article describes how to use TigerVNC to share files on Debian systems. You need to install the TigerVNC server first and then configure it. 1. Install the TigerVNC server and open the terminal. Update the software package list: sudoaptupdate to install TigerVNC server: sudoaptinstalltigervnc-standalone-servertigervnc-common 2. Configure TigerVNC server to set VNC server password: vncpasswd Start VNC server: vncserver:1-localhostno
