安装

官网

CentOS

Install the prerequisites:

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:

yum-config-manager --enable nginx-mainline

To install nginx, run the following command:

yum -y 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.

安装好后删除repo

mv /etc/yum.repos.d/nginx.repo /etc/yum.repos.d/nginx.repo.b

Debian

Install the prerequisites:

apt install curl gnupg2 ca-certificates lsb-release debian-archive-keyring

Import an official nginx signing key so apt could verify the packages authenticity. Fetch the key:

curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
    | tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null

Verify that the downloaded file contains the proper key:

gpg --dry-run --quiet --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg

The output should contain the full fingerprint 573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62 as follows:

pub rsa2048 2011-08-19 [SC] [expires: 2024-06-14]
573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62
uid nginx signing key <signing-key@nginx.com>

If the fingerprint is different, remove the file.

To set up the apt repository for stable nginx packages, run the following command:

echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
http://nginx.org/packages/debian `lsb_release -cs` nginx" \
    | tee /etc/apt/sources.list.d/nginx.list

Set up repository pinning to prefer our packages over distribution-provided ones:

echo -e "Package: *\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n" \
    | tee /etc/apt/preferences.d/99nginx

To install nginx, run the following commands:

apt update
apt install nginx

安装好后删除list

rm -rf /etc/apt/sources.list.d/nginx.list

配置

启动：

service nginx start

守护：

systemctl enable nginx
systemctl start nginx
systemctl restart nginx
systemctl stop nginx
systemctl disable nginx

配置文件

程序配置文件：/etc/nginx/nginx.conf
默认配置文件：/etc/nginx/conf.d/default.conf
配置文件目录：/etc/nginx/conf.d/

如果要用反代：
在/etc/nginx/nginx.conf文件的http字段加入：

map $http_upgrade $connection_upgrade {
default upgrade;
''      close;
}
