1. 下载源码包
[root@webserver ~]# cd /usr/local/src/
[root@webserver src]# curl -O https://nginx.org/download/nginx-1.20.2.tar.gz
2. 安装依赖相关
[root@webserver ~]# yum install pcre pcre-devel -y #rewrite正则相关pcre : URL重写软件，实现伪静态\URL跳转等SEO优化，pcre意思就是Perl的正则表达式。
[root@webserver ~]# yum install openssl openssl-devel -y #https加密访问用它。
# 检查下载没问题
[root@webserver ~]# rpm -qa pcre pcre-devel openssl openssl-devel
pcre-8.32-17.el7.x86_64
pcre-devel-8.32-17.el7.x86_64
openssl-devel-1.0.2k-25.el7_9.x86_64
openssl-1.0.2k-25.el7_9.x86_64
3.创建nginx用户
[root@webserver src]# useradd -u 1111 -s /sbin/nologin -M www
4. 编译安装
[root@webserver ~]# cd /usr/local/src/
[root@webserver src]# ls
nginx-1.20.2.tar.gz
[root@webserver src]# tar xf nginx-1.20.2.tar.gz
[root@webserver src]# cd nginx-1.20.2/
[root@webserver nginx-1.20.2]# ./configure --user=www --group=www --prefix=/application/nginx-1.20.2/ --with-http_stub_status_module --with-http_ssl_module --with-pcre
[root@webserver nginx-1.20.2]# make -j 4
[root@webserver nginx-1.20.2]# make install
安装后操作
5.建立软链接
[root@webserver nginx-1.20.2]# ln -s /application/nginx-1.20.2/ /application/nginx
6.启动nginx
# 查看80端口是否占用
[root@webserver nginx-1.20.2]# lsof -i :80
# 查看nginx配置是否有问题
[root@webserver nginx-1.20.2]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.20.2//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.20.2//conf/nginx.conf test is successful
# 将nginx路径添加到PATH变量
[root@webserver ~]# echo 'export PATH="/application/nginx/sbin/:$PATH"' >> /etc/profile
[root@webserver ~]# . /etc/profile
7.将nginx注册到系统服务单元
# 在另外一台装有nginx的主机webserver2上查看yum安装的nginx相关文件位置,找到nginx.service文件vim打开并复制其内容
[root@webserver2 ~]# rpm -ql nginx
