Today, the editor shares with you the detailed explanation of rpm, yum and source code installation software in linux. I believe many people don't know much about it. In order to make you understand better, I summarized the following contents for you. Let's look down together. I'm sure you'll get something.

Detailed explanation of rpm, yum and source code installation software

8.1rpm installation

Rpm [option] package name main option-I install-e uninstall-U upgrade-Q find secondary option-ⅴ display procedure-h-- hash query-a-all query all installed packages-f-file query owns sr0

Yum source

[root@MiWiFi-R3L-srv etc] # cd / etc/yum.repos.d [root@MiWiFi-R3L-srv yum.repos.d] # lsCentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repoCentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo [root@MiWiFi-R3L-srv etc] # cd / etc/yum.repos.d [root@MiWiFi-R3L-srv yum.repos.d] # lsCentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media. RepoCentOS- Vault.repoCentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo [root@MiWiFi-R3L-srv yum.repos.d] # ^ C [root@MiWiFi-R3L-srv yum.repos.d] # mkdir xx [root@MiWiFi-R3L-srv yum.repos.d] # mv * .repo xx/ [root@MiWiFi-R3L-srv yum.repos.d] # lsxx

Then create a new 1.repo under this directory

The content is

[ftp] name=testbaseurl= ftp://localhost/pubgpgcheck=0

Now the yum works.

[root@MiWiFi-R3L-srv yum.repos.d] # vim 1.repo [root@MiWiFi-R3L-srv yum.repos.d] # yum install http loaded plug-in: fastestmirror LangpacksLoading mirror speeds from cached hostfileftp | 3.6 kB 00:00 (1amp 2): ftp/group_gz | 165kB 00:00 (2amp 2): ftp/primary_db | 3.2MB 00:00 No software package http is available. Error: no processing required

Baseurl can be ftp://

It can also be file://

The content is

[loacl] name=localbaseurl= file:///mnt/dvdgpgcheck=0

Three / because the third / means to follow the directory.

Install the third party source, epel,aliyun, source of Tsinghua University

Either way, just install the file rpm, and then you will have the source repo file you just downloaded in / etc/yum.repos.d.

8.3yum command

Configuration of the yum installation, in the / etc/yum.conf file

[main] cachedir=/var/cache/yum/$basearch/$releaseverkeepcache=0debuglevel=2logfile=/var/log/yum.logexactarch=1obsoletes=1gpgcheck=1plugins=1installonly_limit=5bugtracker_url= http://bugs.centos.org/set_project.php?project_id=23&ref=http://bugs.centos.org/bug_report_page.php?category=yumdistroverpkg=centos-release

Cachedir default download place $basearch is your architecture / the second is your version

Keepcache is whether to save after downloading.

Next, Zhu ordered

The name of the installupdateremovesearchGrouplistyum list package

8.5 Source installation

1. download

First download the source code, and then decompress it, because there is a graphical interface, direct operation on the line.

two。 Decompression

It is nginx, then decompress it, open it and look at it.

[wangzirui@laotie ~] $cd nginx-1.17.8/ [wangzirui@laotie nginx-1.17.8] $lsauto CHANGES.ru configure html man srcCHANGES conf contrib LICENSE README

3. Check

The configure inside is an executable file.

[wangzirui@laotie nginx-1.17.8] $. / configure checking for OS + Linux 3.10.0-1062.el7.x86_64 x86_64checking for C compiler. Not found./configure: error: C compiler cc is not found

You can't run it if you run it directly, because you need to compile this file.

So you need to install gcc

[root@laotie nginx-1.17.8] # yum-y install gcc

At this time, it will be carried out after it has been installed.

. / configure

Will prompt for the lack of qcre, and then install qcre

[root@laotie nginx-1.17.8] # yum list pcre loaded plug-in: fastestmirror LangpacksLoading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.163.com installed package pcre.x86_64 8.32-17.el7 @ anaconda installable package pcre.i686 8.32-17.el7 base [root @ laotie nginx-1.17.8] # yum-y install pcre-devel

Just install it, and then make it to generate the installation file.

4. Compile

[root@laotie nginx-1.17.8] # make

Next is make install. After execution, the installation is successful.

5. Installation

[root@laotie nginx-1.17.8] # make install

Then enter the directory and execute the executable file.

6. Execution

[root@laotie nginx-1.17.8] # cd / usr/local/nginx [root@laotie nginx] # lsconf html logs sbin [root@laotie nginx] # cd sbin [root@laotie sbin] # lsnginx

And then execute

. / nginx

Just enter localhost. You can see the html of nginx.
