Galaxy Kirin server system building local and LAN Yum source

        yum Main management based on rpm Software package , It can be upgraded automatically 、 install 、 Delete rpm software package , At the same time, it can automatically find and solve rpm Dependencies between packages , And there is no need for administrators to 、 Install each one manually rpm package .yum It can be from one or more repo Configured in the file repo Warehouse , adopt http or ftp The agreement is from repo The warehouse obtains the necessary information , Then download the relevant software package . such , Local users set up different repo Warehouse , It is convenient to upgrade and maintain the system .

preparation ： Prepare a galaxy Kirin server operating system image of the same version as this server , Orders available nkvers Check the system version

One 、 Local yum Source building

1、 Create a mirror mount Directory , command ：mkdir   /mnt/iso, And mount the image to this directory , command ：mount  XXX.iso   /mnt/iso. After the mount is successful, you can use the command df  -hT View the mount .

 2、 modify yum The configuration file /etc/yum.repos.d/kylin_x86_64.repo, The original yum Configuration file backup , And then make changes .

cd /etc/yum.repos.d
cp kylin_x86_64.repo  kylin_x86_64.repo.bak
vim  kylin_x86_64.repo

  Can be kylin_x86_64.repo The file is modified as shown in the following figure

###Kylin Linux Advanced Server 10 - os repo###

[ks10-adv-os]         #yum Source name 
name = Kylin Linux Advanced Server 10 - Os   # Full name 
baseurl = file:///mnt/iso                    # Download source address 
gpgcheck = 0                                 # Whether to check rpm Digital signature of the package ,1 Means to check ,0 Means not to check 
enabled = 1                                  # Is it enabled? ,1 Means to enable ,0 Indicates that... Is not enabled 

3、 Remove the original yum Information , Load new cache , Such a new local yum The source can be used .

#yum clean all
#yum makecache

Two 、 LAN yum Source building

        It's usually passed apache To build http Of yum Source , This use nginx Conduct the construction demonstration , First download nginx Source package , Download address ：Index of /download/Index of /download/https://nginx.org/download/nginx-1.16.1.tar.gz（ If the image has been mounted and the local yum Source , It can be installed directly online ：yum  -y  install  nginx, This demo uses the source code package ）

         Online installation nginx After success ,nginx Configuration file in /etc/nginx/nginx.conf Next , The configuration file is modified as shown in the following figure , Commands available ：systemctl  start nginx 、systemctl  stop   nginx 、systemctl  status nginx To start up 、 stop it 、 see nginx state . Other operations are the same as source package installation .

1、 Decompress the source package , Compilation and installation nginx

# tar -xf nginx-1.16.1.tar.gz                decompression nginx Source package 
# cd  nginx-1.16.1                           Switch to the decompressed nginx Folder 
# ./configure --prefix=/usr/local/nginx     configure Command to check whether the current system meets the installation conditions , Specify how to install 、 The installation directory 、 Turn on the module function .--prefix： Specify the installation directory 
# make -j4                                   Use gcc Compile , Generate the main binary file （-j4  Appoint 4 individual cpu Compile together , Default one cpu Compile , Faster ）
# make install                               Install binaries to the host  

2、nginx After installation , establish yum Source warehouse directory , To mount iso Copy the image to this directory

# mkdir /mnt/nginx-yum                 establish yum Warehouse directory 
# mount Kylin-Server-10-SP2-Release-Build09-20210524.iso  /mnt/iso    Mount the image 
# cp -rp /mnt/iso/*  /mnt/nginx-yum/    Copy the image file to yum Warehouse 

After copying , Use the command to check whether the copy is successful

​

3、 modify nginx In profile http Module server modular .  command ：vim /usr/local/nginx/conf/nginx.conf

​

Check the local firewall policy after modifying the port , If the firewall is turned on , Should be 8899 The port is added to the firewall white list , And overload firewalls

firewall-cmd --permanent --zone=public --add-port=8484/tcp    add to 8899 port 
firewall-cmd --zone=public --list-ports                       View open ports 
systemctl   reload   firewalld                                Reload firewall 

  4、 After modifying the configuration file , Check whether the configuration file is modified correctly and restart nginx. 

​

 5、 Modify other machines in the LAN yum The configuration file /etc/yum.repos.d/kylin_x86_64.repo in baseurl Is the local address .​

Remove the original yum Information , Load new cache  

 #yum clean all
#yum makecache

6、 After the above steps are completed , LAN yum The source can be used , You can download a software to test , You can also enter ：http://ip:8899 Visit .
