一次LINUX测验

Posted 2020-09-22

           一次LINUX测验

 首次写linux文章，如有不足，还望读者不吝赐教！

一、1.在安装好的Linux系统中新建一个逻辑卷，mail原始大小为500M ，然后为其扩容100M 。

  [[email protected] ~]#pvcreate /dev/sdb2

  [[email protected] ~]#fdisk /dev/sdb2

   [[email protected] ~]mkfs.ext3 /dev/sdb2

   [[email protected] ~]#pvcreate /dev/sdb2

  [[email protected] ~]#vgcreate vg0 /dev/sdb2

  [[email protected] ~]#lvcreate -L 500M -n mail vg0

            创建lvm大小为500M，名称为mail，从vg0中调容量

  [[email protected] ~]# lvextend -L +100M /dev/vg0/mail

  Size of logical volume vg0/lv0 changed from 100M (20480 extents) to 600M (28160 extents).   添加成功

  Logical volume lv0 successfully resized.##     创建成功

 

二、在安装好的Linux系统中安装apache服务器，硬且搭建基于域名的虚拟主机服务，提供两个站点。

         安装apache

     卸载httpd软件及相关软件包

[[email protected] ~]#rpm -e httpd httpd-manual webalizer subversion mod_python mod_ssl mod_perl system-config-httpd php php-cli php-ldap php-common mysql dovecot --nodeps 

        

         解压软件包

[[email protected] ~]#tar zxvf httpd-2.4.25.tar.gz -C /opt/

[[email protected] ~]# tar -zxvf apr-1.5.2.tar.gz -C /opt/

[[email protected] ~]#tar -zxvf apr-util-1.5.4.tar.gz -C /opt/

[[email protected] ~]#cp -r apr-1.5.2/ httpd-2.4.25/srclib/apr

[[email protected] ~]#cp -r apr-util-1.5.4/ httpd-2.4.25/srclib/apr-util

     源码编译安装Apache

[[email protected] ~]# cd /opt/httpd-2.4.25/

[[email protected] ~]# ./configure \

--prefix=/usr/local/apache \

--enable-so \

--enable-rewrite \

--enable-mods-shared=most \

--with-mpm=worker \

--disable-cgid \

--disable-cgi

[[email protected]linuxidc 63 httpd-2.4.25]# make -j 4  

     编译，将编译程序变为可执行程序

[[email protected]linuxidc 63 httpd-2.4.25]# make install  安装

[[email protected]linuxidc63 httpd-2.4.25]# vim /etc/init.d/httpd

#!/bin/sh

# chkconfig: 2345 85 15

# description: Apache is a World Wide Web server.

[[email protected]linuxidc63 httpd-2.4.25]# chmod  +x  /etc/init.d/httpd

 

-s /usr/local/apache/conf/httpd.conf /etc/httpd.conf

[[email protected]linuxidc63 httpd-2.4.25]# service iptables stop 

             基于域名的虚拟主机

[[email protected]linuxidc63 conf.d]# mkdir /opt/accp [[email protected]linuxidc63 conf.d]# mkdir /opt/benet

[[email protected]linuxidc63 conf.d]# echo "<h1>welcome accp<h1>" > /opt/accp/index.html

[[email protected]linuxidc63 conf.d]# echo "<h1>welcome benet<h1>" > /opt/benet/index.html

[[email protected]linuxidc63 conf.d]# service httpd restart

[[email protected]linuxidc63 conf.d]# service iptables stop  关闭防火墙

[[email protected]linuxidc63 conf.d]# vim vhost.conf

 Listen 192.168.80.193:8080

<VirtualHost 192.168.80.193:8080>

    DocumentRoot /opt/accp/

    ServerName www.accp.com

    ErrorLog logs/accp.com-error_log

    CustomLog logs/accp.com-access_log common

</VirtualHost>

<Directory "/opt/accp">

    Options Indexes MultiViews FollowSymLinks

    AllowOverride None

    Order allow,deny

    Allow from all

    Require all granted

</Directory>

 

<VirtualHost 192.168.80.193:80>

    ServerAdmin [email protected]

    DocumentRoot /opt/benet/

    ServerName www.benet.com

    ErrorLog logs/benet.com-error_log

    CustomLog logs/benet.com-access_log common

</VirtualHost>

<Directory "/opt/benet">

    Options Indexes MultiViews FollowSymLinks

    AllowOverride None

    Order allow,deny

    Allow from all

    Require all granted

</Directory>

 

 

 

三、配置FTP虚拟用户功能，使TOM用户可以上传下载，下载速度限制为500K，而JACK用户只能下载，速度为300K。

安装

[[email protected] ~]# rpm -ivh /mnt/Packages/vsftpd-2.2.2-6.el6_0.1.x86_64.rpm

[[email protected] ~]# rpm -ivh /mnt/Packages/lftp-4.0.9-1.el6.x86_64.rpm3

[[email protected] ~]# service vsftpd restart

[[email protected] ~]#chkconfig vsftpd on

[[email protected] ~]# netstat -antup | grep ftp

tcp        0      0 0.0.0.0:21                  0.0.0.0:*                   LISTEN      11725/vsftpd

   

 [[email protected]]#vim /etc/vsftpd/vsftpd_virtualuser.txt  

Tom

888888

Jack

888888

 此文件格式要示奇数行用户名、偶数行密码

[[email protected]linuxidc63 ~]# rpm -ivh /mnt/Packages/db4-utils-4.7.25-18.el6_4.x86_64.rpm

[[email protected]linuxidc63 ~]# db_load -T -t hash -f /etc/vsftpd/vsftpd_virtualuser.txt  /etc/vsftpd/vsftpd_virtualuser.db

[[email protected] ~]# vim  /etc/pam.d/vsftpd 

auth required/lib64/security/pam_userdb.so  db=/etc/vsftpd/vsftpd_virtualuser

accountrequired/lib64/security/pam_userdb.so  db=/etc/vsftpd/vsftpd_virtualuser

[[email protected] vsftpd]# useradd -d /var/ftp/jack ftpuser

[[email protected] vsftpd]# useradd -d /var/ftp/tom ftpvip

[[email protected] vsftpd]# chmod -R 300 /var/ftp/jack/    只允许下载

 [[email protected] vsftpd]# chmod -R 500 /var/ftp/tom/    允许上传和下载

 

  建立虚拟配置

[[email protected]~]# grep vuserconfig /etc/vsftpd/vsftpd.conf   

user_config_dir=/etc/vsftpd/vuserconfig

[[email protected] ~]# mkdir /etc/vsftpd/vuserconfig

[[email protected] ~]# touch /etc/vsftpd/vuserconfig/tom

[[email protected] ~]# touch /etc/vsftpd/vuserconfig/jack

   

 

 

[[email protected] ~]#vim /etc/vsftpd/vuserconfig/jack

  guest_enable=yes   开启虚拟帐号登录

  anon_max_rate=300000  限定传输速率为300k/s

  #对于虚拟用户默认就是可以下载的默认是不能上传的

[[email protected] ~]#vim /etc/vsftpd/vuserconfig/tom

write_enable=yes

anon_mkdir_write_enable=yes

anon_upload_enable=yes   允许虚拟用户上传

anon_max_rate=500000

anon_other_write_enable=YES 

重启vsftpd 使配置生效

[[email protected] ~]# service vsftpd restart
