篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了web服务之NGinx安装相关的知识，希望对你有一定的参考价值。
系统和EPEL源的中nignx版本较旧,可以安装官方源的最新版本
官方包链接:
http://nginx.org/en/linux_packages.html
官方 yum 源链接
http://nginx.org/en/linux_packages.html#RHEL-CentOS
范例: 通过官方 yum 源安装nginx
[root@centos8 ~]# cat /etc/yum.repos.d/nginx.repo
[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
范例：
#带有自动日志切割功能
[root@centos8 ~]# cat /etc/logrotate.d/nginx /var/log/nginx/*log
create 0664 nginx root
daily
rotate 10
missingok
notifempty
compress
sharedscripts
postrotate
/bin/kill -USR1 `cat /run/nginx.pid 2>/dev/null` 2>/dev/null || true
endscript
使用安装完成的二进制文件nginx
[root@centos8 ~]# nginx -h
nginx version: nginx/1.18.0
Usage: nginx [-?hvVtTq] [-s signal] [-c filename] [-p prefix] [-g directives]
Options:
-?,-h : this help
-v : show version and exit
-V : show version and configure options then exit #显示版本和编译参数
-t : test configuration and exit #测试配置文件是否异
常
-T : test configuration, dump it and exit #测试并打印
-q : suppress non-error messages during configuration testing #静默模
式
-s signal : send signal to a master process: stop, quit, reopen, reload #发
送信号,reload信号 会生成新的worker,但master不会重新生成
-p prefix : set prefix path (default: /etc/nginx/)
#指定Nginx 目录
-c filename : set configuration file (default: /etc/nginx/nginx.conf)
#配置文件路径
-g directives : set global directives out of configuration file#设置全局指令,注意
和配置文件不要同时配置,否则冲突
验证 Nginx
[root@centos8 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@centos8 ~]# nginx -V

Nginx 编译安装
编译器介绍
源码安装需要提前准备标准的编译器，GCC的全称是（GNU Compiler collection），其有GNU开发，并以
GPL即LGPL许可，是自由的类UNIX即苹果电脑Mac OS X操作系统的标准编译器，因为GCC原本只能处理C语
言，所以原名为GNU C语言编译器，后来得到快速发展，可以处理C++,Fortran，pascal，objective-
C，java以及Ada等其他语言，此外还需要Automake工具，以完成自动创建Makefile的工作，Nginx的一些
模块需要依赖第三方库，比如: pcre（支持rewrite），zlib（支持gzip模块）和openssl（支持ssl模
块）等。
官方源码包下载地址：
https://nginx.org/en/download.html
范例: 编译安装
[root@centos8 ~]# yum -y install gcc pcre-devel openssl-devel zlib-devel
[root@centos8 ~]# useradd -s /sbin/nologin nginx
[root@centos8 ~]# cd /usr/local/src/
[root@centos8 src]# wget http://nginx.org/download/nginx-1.18.0.tar.gz
[root@centos8 src]# tar xf nginx-1.18.0.tar.gz
[root@centos8 src]# cd nginx-1.18.0/
[root@centos8 nginx-1.18.0]#./configure --prefix=/apps/nginx \\
--user=nginx \\
--group=nginx \\
--with-http_ssl_module \\
--with-http_v2_module \\
--with-http_realip_module \\
--with-http_stub_status_module \\
--with-http_gzip_static_module \\
--with-pcre \\
--with-stream \\
--with-stream_ssl_module \\
--with-stream_realip_module
[root@centos8 nginx-1.18.0]# make && make install
#修改权限
[root@centos8 nginx-1.18.0]# chown -R nginx.nginx /apps/nginx
#生成目录如下：
[root@centos8 nginx-1.18.0]#ll /apps/nginx/
total 0
drwxr-xr-x 2 root root 333 Sep 22 18:49 conf
drwxr-xr-x 2 root root 40 Sep 22 18:49 html
drwxr-xr-x 2 root root 6 Sep 22 18:49 logs
drwxr-xr-x 2 root root 19 Sep 22 18:49 sbin
conf：保存nginx所有的配置文件，其中nginx.conf是nginx服务器的最核心最主要的配置文件，其他
的.conf则是用来配置nginx相关的功能的，例如fastcgi功能使用的是fastcgi.conf和
fastcgi_params两个文件，配置文件一般都有个样板配置文件，是文件名.default结尾，使用的使用将其
复制为并将default去掉即可。
html目录中保存了nginx服务器的web文件，但是可以更改为其他目录保存web文件,另外还有一个50x的web
文件是默认的错误页面提示页面。
logs：用来保存nginx服务器的访问日志错误日志等日志，logs目录可以放在其他路径，比
如/var/logs/nginx里面。
sbin：保存nginx二进制启动脚本，可以接受不同的参数以实现不同的功能。
范例：创建 Nginx 自启动文件
#复制同一版本的nginx的yum安装生成的service文件

利用 ansible 的roles 实现 nginx 编译安装
注意：如果需要安装第三方包最好换个路径，不然ansible执行会报错，自己挖的坑，自己承受吧。（编译添加第三方包这里不演示了，因为全部的路径都要改） 这个roles需要有基础的，零基础不建议看
在编译NGINX时需要第三方包的加入下面两条命令：
--add-module=/xxx/ansible/roles/nginx/meta/echo-nginx-module \\
--add-module=/xxx/ansible/roles/nginx/meta/ngx_cache_purge \\
# 下载第三包

启用某个主机组作为roles角色
[root@sz-kx-centos8 ~]# cat /etc/ansible/roles/install_nginx.yml
---
- hosts: webser

切换到roles目录下
[root@sz-kx-centos8 ~]# cd /etc/ansible/roles/
[root@sz-kx-centos8 /etc/ansible/roles]# ls
install_nginx.yml nginx
[root@sz-kx-centos8 /etc/ansible/roles]# pwd
/etc/ansible/roles
检查配置（这里检查不会解包，执行过程会报错）
[root@sz-kx-centos8 /etc/ansible/roles]# ansible-playbook -C install_nginx.yml
执行
[root@sz-kx-centos8 /etc/ansible/roles]# ansible-playbook install_nginx.yml
这步可以使用ansible的shell模块远程检查端口80是否已经打开
[root@sz-kx-centos8 /etc/ansible/roles]# ansible webser -m shell -a "ss -tnlp | grep 80"

报错：
编译时报错："./configure: error: no /etc/ansible/roles/nginx/meta/echo-nginx-module/config was found"]，，原因是找不到这个包？？？
解决方法：1）编译安装NGINX时不要加这两个进去编译：
--add-module=/xxx/ansible/roles/nginx/meta/echo-nginx-module \\
--add-module=/xxx/ansible/roles/nginx/meta/ngx_cache_purge \\
2）如果真需要这第三方包的，目前不确定原因，据说是因为/etc/ansible报错，重新做一个roles角色路径吧。。。
