"NGINX最新官方权威指南，包含高级负载均衡的食谱" 这篇文档，即《NGINX Cookbook》的最新更新版，是针对NGINX Web服务器和负载均衡器的一份详尽指南。NGINX是一款高性能的HTTP和反向代理服务器，同时也是邮件传输代理，广泛用于高流量网站，因其轻量级、高效能的特点而备受青睐。在描述中提到的“Advanced Recipes for High Performance Load Balancing”，意味着这份PDF深入探讨了如何利用NGINX实现高效的负载均衡，这对于大型分布式系统或微服务架构至关重要。负载均衡能够确保服务器集群中的工作负载均匀分布，提高系统的可用性和可靠性，同时避免单点故障。 NGINX Plus是NGINX的商业版本，提供了一些高级功能，如内置的负载均衡器、内容缓存和Web服务器。据描述，相比硬件应用交付控制器和Web应用防火墙（WAF），NGINX Plus可节省超过80%的成本，但性能和特性却毫不逊色。它还支持微服务的高性能应用交付，确保了服务的高可用性。文档中特别提到了NGINX Web Application Firewall (WAF)，这是一个基于ModSecurity的安全组件，可以防止复杂的Layer 7攻击，保护应用程序免受网络威胁。NGINX WAF是NGINX Plus的一部分，试用版包括了30天的免费试用期。此外，NGINX Plus还包含了JWT（JSON Web Token）认证、高可用性、NGINX Plus API等独家功能，这些都进一步增强了其在复杂企业环境中的适应性和灵活性。通过集成负载均衡器、内容缓存、Web服务器和Web应用防火墙，NGINX Plus大大简化了基础设施管理，减少了系统复杂性，避免了“基础设施蔓延”。《NGINX Cookbook》2019更新版是一份全面的参考资料，对于想要深入了解和优化NGINX部署，特别是关注性能提升和安全防护的IT专业人士来说，具有极高的价值。

trusty, xenial, artful, or bionic for ubuntu. Then, run the fol‐

lowing commands:

wget http://nginx.org/keys/nginx_signing.key

apt-key add nginx_signing.key

apt-get update

apt-get install -y nginx

/etc/init.d/nginx start

Discussion

The file you just created instructs the apt package management sys‐

tem to utilize the Official NGINX package repository. The com‐

mands that follow download the NGINX GPG package signing key

and import it into apt. Providing apt the signing key enables the apt

system to validate packages from the repository. The apt-get

update command instructs the apt system to refresh its package list‐

ings from its known repositories. After the package list is refreshed,

you can install NGINX Open Source from the Official NGINX

repository. After you install it, the final command starts NGINX.

1.2 Installing on RedHat/CentOS

Problem

You need to install NGINX Open Source on RedHat or CentOS.

Solution

Create a file named /etc/yum.repos.d/nginx.repo that contains the

following contents:

[nginx]

name=nginx repo

baseurl=http://nginx.org/packages/mainline/OS/OSRELEASE/$basearch/

gpgcheck=0

enabled=1

Alter the file, replacing OS at the end of the URL with rhel or cen

tos, depending on your distribution. Replace OSRELEASE with 6 or 7

for version 6.x or 7.x, respectively. Then, run the following

commands:

yum -y install nginx

systemctl enable nginx

2 | Chapter 1: Basics

systemctl start nginx

firewall-cmd --permanent --zone=public --add-port=80/tcp

firewall-cmd --reload

Discussion

The file you just created for this solution instructs the yum package

management system to utilize the Official NGINX Open Source

package repository. The commands that follow install NGINX Open

Source from the Official repository, instruct systemd to enable

NGINX at boot time, and tell it to start it now. The firewall com‐

mands open port 80 for the TCP protocol, which is the default port

for HTTP. The last command reloads the firewall to commit the

changes.

1.3 Installing NGINX Plus

Problem

You need to install NGINX Plus.

Solution

Visit http://cs.nginx.com/repo_setup. From the drop-down menu,

select the OS you’re installing and then follow the instructions. The

instructions are similar to the installation of the open source solu‐

tions; however, you need to install a certificate in order to authenti‐

cate to the NGINX Plus repository.

Discussion

NGINX keeps this repository installation guide up to date with

instructions on installing the NGINX Plus. Depending on your OS

and version, these instructions vary slightly, but there is one com‐

monality. You must log in to the NGINX portal to download a cer‐

tificate and key to provide to your system that are used to

authenticate to the NGINX Plus repository.

1.3 Installing NGINX Plus | 3

1.4 Verifying Your Installation

Problem

You want to validate the NGINX installation and check the version.

Solution

You can verify that NGINX is installed and check its version by

using the following command:

$ nginx -v

nginx version: nginx/1.15.3

As this example shows, the response displays the version.

You can confirm that NGINX is running by using the following

command:

$ ps -ef | grep nginx

root 1738 1 0 19:54 ? 00:00:00 nginx: master process

nginx 1739 1738 0 19:54 ? 00:00:00 nginx: worker process

The ps command lists running processes. By piping it to grep, you

can search for specific words in the output. This example uses grep

to search for nginx. The result shows two running processes, a mas

ter and worker. If NGINX is running, you will always see a master

and one or more worker processes. For instructions on starting

NGINX, refer to the next section. To see how to start NGINX as a

daemon, use the init.d or systemd methodologies.

To verify that NGINX is returning requests correctly, use your

browser to make a request to your machine or use curl:

$ curl localhost

You will see the NGINX Welcome default HTML site.

Discussion

The nginx command allows you to interact with the NGINX binary

to check the version, list installed modules, test configurations, and

send signals to the master process. NGINX must be running in

order for it to serve requests. The ps command is a surefire way to

determine whether NGINX is running either as a daemon or in the

foreground. The default configuration provided by default with

4 | Chapter 1: Basics

NGINX runs a static site HTTP server on port 80. You can test this

default site by making an HTTP request to the machine at local

host as well as the host’s IP and hostname.

1.5 Key Files, Commands, and Directories

Problem

You need to understand the important NGINX directories and

commands.

Solution

NGINX les and directories

/etc/nginx/

The /etc/nginx/ directory is the default configuration root for

the NGINX server. Within this directory you will find configu‐

ration files that instruct NGINX on how to behave.

/etc/nginx/nginx.conf

The /etc/nginx/nginx.conf file is the default configuration entry

point used by the NGINX service. This configuration file sets up

global settings for things like worker process, tuning, logging,

loading dynamic modules, and references to other NGINX con‐

figuration files. In a default configuration, the /etc/nginx/

nginx.conf file includes the top-level http block, which includes

all configuration files in the directory described next.

/etc/nginx/conf.d/

The /etc/nginx/conf.d/ directory contains the default HTTP

server configuration file. Files in this directory ending in .conf

are included in the top-level http block from within the /etc/

nginx/nginx.conf file. It’s best practice to utilize include state‐

ments and organize your configuration in this way to keep your

configuration files concise. In some package repositories, this

folder is named sites-enabled, and configuration files are linked

from a folder named site-available; this convention is depre‐

cated.

1.5 Key Files, Commands, and Directories | 5

/var/log/nginx/

The /var/log/nginx/ directory is the default log location for

NGINX. Within this directory you will find an access.log file and

an error.log file. The access log contains an entry for each

request NGINX serves. The error log file contains error events

and debug information if the debug module is enabled.

NGINX commands

nginx -h

Shows the NGINX help menu.

nginx -v

Shows the NGINX version.

nginx -V

Shows the NGINX version, build information, and configura‐

tion arguments, which shows the modules built in to the

NGINX binary.

nginx -t

Tests the NGINX configuration.

nginx -T

Tests the NGINX configuration and prints the validated config‐

uration to the screen. This command is useful when seeking

support.

nginx -s signal

The -s flag sends a signal to the NGINX master process. You

can send signals such as stop, quit, reload, and reopen. The

stop signal discontinues the NGINX process immediately. The

quit signal stops the NGINX process after it finishes processing

inflight requests. The reload signal reloads the configuration.

The reopen signal instructs NGINX to reopen log files.

Discussion

With an understanding of these key files, directories, and com‐

mands, you’re in a good position to start working with NGINX.

With this knowledge, you can alter the default configuration files

and test your changes by using the nginx -t command. If your test
