Install nginx with rpm command
Steps to install nginx
rpm -ivh nginx-1.18.0-1.el7.ngx.x86_64.rpm is installed through nginx download package
- i is short for install
- v displays detailed installation process information
- h displays the progress bar of the installation
rpm -qc nginx query nginx installation location information
- q means query
- c configfiles configuration file means to list all configuration files
Remember key documents
/ etc/nginx/conf.d/default.conf # main configuration file
/ etc/nginx/nginx.conf # sub configuration file
RPM -ql nginx all the operation information of nginx can be found in your system
- q is the query of query
- l means list, that is, list the files in the software package
Remember key documents
/etc/nginx/conf.d/default.conf
/etc/nginx/nginx.conf
/etc/sysconfig/nginx
/usr/sbin/nginx # execute command
/usr/share/nginx/html # code directory self written web pages
/var/log/nginx # log directory
Start service - understand
Systemctl start nginx # start nginx
Iptables - F # turn off firewall
Open Google browser and enter the ip address 10.0.0.100

You can perform the following, just refresh the browser content
[root@centos7-100 ~]# systemctl start nginx [root@centos7-100 ~]# iptables -F [root@centos7-100 ~]# echo zhaocheng >/usr/share/nginx/html/index.html
Inspection after installation:
Browser input: 10.0.0.100
Uninstall:
rpm -e nginx uninstall nginx
rpm -evh nginx displays the unloading process in detail
Install nginx using the yum command
Advantages and disadvantages of yum installation:
1. Install yum. You can download common software from the warehouse without knowing the exact full name of the software package
2.yum installation can automatically solve dependency problems
3. Must be networked (extranet)
yum source concept:
1.Basics base Source and expansion epel source 2.Third party sources, nginx,zabbix 3.yum The source file is*.repo End, put in/etc/yum.repos.d/*.repo
Common yum source address
http://mirrors.aliyun.com/repo/ https://mirrors.tuna.tsinghua.edu.cn/ https://mirrors.tuna.tsinghua.edu.cn/help/centos/ https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
yum common commands:
1. Enter the yum source directory
CD / etc / yum. Repos. D / #cd enter this directory
View base and epel sources
[root@centos7-100 ~]# cd /etc/yum.repos.d/ [root@centos7-100 yum.repos.d]# ls CentOS-Base.repo CentOS-CR.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Media.repo CentOS-Sources.repo CentOS-Vault.repo CentOS-x86_64-kernel.repo [root@centos7-100 yum.repos.d]# vim CentOS-Base.repo
Networking manual update yum cache
yum makecache fast
Download Ali source and specify a file name to save
wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
Find the aliyuncs keyword in the CentOS-Base.repo file, and d is all lines to delete the keyword
sed -i '/aliyuncs/d' CentOS-Base.repo can also be deleted with vim, but it is very troublesome. You can use this command to solve it in one step
2. Update yum cache
yum makecache fast # updating yum cache is equivalent to updating dishes
yum common commands
yum search nginx # to view the packages with nginx in the current directory warehouse
yum list |grep "nginx" # query the software list containing nginx keyword
Yum install nginx -y #yum install nginx -y without manual confirmation
View installed nginx details
yum info nginx
[root@centos7-100 yum.repos.d]# yum info nginx Plug in loaded: fastestmirror Repository epel is listed more than once in the configuration Repository epel-debuginfo is listed more than once in the configuration Repository epel-source is listed more than once in the configuration Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Installed packages name : nginx framework : x86_64 period : 1 edition : 1.20.1 release : 2.el7 size : 1.7 M source : installed From source: epel brief introduction : A high performance web server and reverse proxy server website : https://nginx.org agreement : BSD describe : Nginx is a web server and a reverse proxy server for HTTP, SMTP, POP3 and : IMAP protocols, with a strong focus on high concurrency, performance and low : memory usage.
Configure the third-party source and the source address of nginx official website
https://nginx.org/en/linux_packages.html
Select stable version
The selected system version is RHEL/CentOS
RHEL/CentOS Install the prerequisites: sudo yum install yum-utils To set up the yum repository, create the file named /etc/yum.repos.d/nginx.repo with the following contents: [nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=1 enabled=1 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true [nginx-mainline] name=nginx mainline repo baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/ gpgcheck=1 enabled=0 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true By default, the repository for stable nginx packages is used. If you would like to use mainline nginx packages, run the following command: sudo yum-config-manager --enable nginx-mainline To install nginx, run the following command: sudo yum install nginx When prompted to accept the GPG key, verify that the fingerprint matches 573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62, and if so, accept it.
Use cat to create a new third-party source and store it in nginx.repo
#Adding single quotation marks' 'means that the system does not consider too many special symbols inside and does not escape special symbols cat >/etc/yum.repos.d/nginx.repo << 'EOF' [nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=1 enabled=1 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true [nginx-mainline] name=nginx mainline repo baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/ gpgcheck=1 enabled=0 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true EOF
Use the ll command to view the nginx source of the / etc/yum.repos.d/ directory
[root@centos7-100 yum.repos.d]# ll Total dosage 48 -rw-r--r--. 1 root root 2523 12 June 26, 2020 CentOS-Base.repo -rw-r--r--. 1 root root 1309 4 August 2020 CentOS-CR.repo -rw-r--r--. 1 root root 649 4 August 2020 CentOS-Debuginfo.repo -rw-r--r--. 1 root root 314 4 August 2020 CentOS-fasttrack.repo -rw-r--r--. 1 root root 630 4 August 2020 CentOS-Media.repo -rw-r--r--. 1 root root 1331 4 August 2020 CentOS-Sources.repo -rw-r--r--. 1 root root 7577 4 August 2020 CentOS-Vault.repo -rw-r--r--. 1 root root 616 4 August 2020 CentOS-x86_64-kernel.repo -rw-r--r--. 1 root root 664 12 June 26, 2020 epel-7.repo -rw-r--r--. 1 root root 664 12 June 26, 2020 epel.repo -rw-r--r--. 1 root root 436 10 May 11:39 nginx.repo
Update the third-party source added to the line using yum makecache fast to update the new software directory
[root@centos7-100 yum.repos.d]# yum makecache fast Plug in loaded: fastestmirror Repository epel is listed more than once in the configuration Repository epel-debuginfo is listed more than once in the configuration Repository epel-source is listed more than once in the configuration Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com base | 3.6 kB 00:00:00 epel | 4.7 kB 00:00:00 extras | 2.9 kB 00:00:00 nginx-stable | 2.9 kB 00:00:00 updates | 2.9 kB 00:00:00 nginx-stable/7/x86_64/primary_db | 67 kB 00:00:00 Metadata cache established
Then use the yum info nginx command to view the latest version of nginx
The first step is to uninstall nginx software
yum remove nginx
Step 2 change the third-party source software directory
[root@centos7-100 yum.repos.d]# yum makecache fast Plug in loaded: fastestmirror Repository epel is listed more than once in the configuration Repository epel-debuginfo is listed more than once in the configuration Repository epel-source is listed more than once in the configuration Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com base | 3.6 kB 00:00:00 epel | 4.7 kB 00:00:00 extras | 2.9 kB 00:00:00 nginx-stable | 2.9 kB 00:00:00 updates | 2.9 kB 00:00:00 Metadata cache established
Step 3: check the latest version that can be installed
[root@centos7-100 yum.repos.d]# yum info nginx Plug in loaded: fastestmirror Repository epel is listed more than once in the configuration Repository epel-debuginfo is listed more than once in the configuration Repository epel-source is listed more than once in the configuration Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Installable packages name : nginx framework : x86_64 period : 1 edition : 1.20.1 release : 2.el7 size : 586 k source : epel/x86_64 brief introduction : A high performance web server and reverse proxy server website : https://nginx.org agreement : BSD describe : Nginx is a web server and a reverse proxy server for HTTP, SMTP, POP3 and : IMAP protocols, with a strong focus on high concurrency, performance and low : memory usage.
yum install command
yum install nginx -y
View the installed nginx version
nginx -v [root@centos7-100 yum.repos.d]# nginx -v nginx version: nginx/1.20.1
Download only, not install
yum install --downloadonly --downloaddir=/opt/ nginx #Only download without installation, and specify the download directory to / opt /
Uninstall software
yum remove nginx After uninstallation is completed, the configuration file will not be deleted and the log will not be deleted.
Source package compilation and installation
Introduction to source package compilation
Code package refers to the source code written by the developer, but it can not be used directly. It needs to be compiled to become executable commands.
Source compilation and installation has several advantages over rpm:
1. You can see the source code. If you have the ability, you can develop it again
2. You can customize the installation path, run the user and other functions
Disadvantages:
The installation configuration is complex and standardization is difficult to implement.
Compilation and installation steps:
Download source code ./configure make make install /opt/nginx/sbin/nginx -t Check syntax /opt/nginx/sbin/nginx /opt/nginx/sbin/nginx -s reload /opt/nginx/sbin/nginx -s stop
Compilation and installation steps:
establish www Users and www group groupadd www -g 1000 useradd www -s /sbin/nologin -M -u 1000 -g 1000
Install dependent packages
yum install openssl-devel pcre-devel gcc -y
Download and unzip the source package
mkdir /data/soft -p #Create a directory to store the software cd /data/soft/ wget http: //nginx.org/download/nginx-1.18.0.tar.gz tar zxvf nginx-1.18.0.tar.gz
Configure compilation parameters
cd nginx-1.18.0 #Adding a \ backslash tells the system that the command has not been executed, but the second line is added ./configure --help # --Help view help information ./configure \ --user=www \ --group=www \ --prefix=/opt/nginx-1.19.9/ \ --with-http_stub_status_module \ --with-http_ssl_module \ --with-pcre
Compile and install
make && make install After the installation is completed, the opt A new one will be created under the directory nginx-1.19.9 [root@centos7-100 opt]# ls nginx-1.19.9 others owner
Create soft connection
ln -s /opt/nginx-1.19.9/ /opt/nginx ls -l /opt/nginx #View soft connection details [root@centos7-100 opt]# ls -l /opt/nginx lrwxrwxrwx. 1 root root 18 10 May 13:39 /opt/nginx -> /opt/nginx-1.19.9/
Check syntax
[root@centos7-100 opt]# /opt/nginx/sbin/nginx -t nginx: the configuration file /opt/nginx-1.19.9//conf/nginx.conf syntax is ok nginx: configuration file /opt/nginx-1.19.9//conf/nginx.conf test is successful
Start service
[root@centos7-100 opt]# /opt/nginx/sbin/nginx [root@centos7-100 opt]#
View nginx version
[root@centos7-100 opt]# /opt/nginx/sbin/nginx -v nginx version: nginx/1.18.0
