编译安装nginx

yum install pcre pcre-devel openssl-devel libxml2-devel libxslt-devel gd-devel perl-ExtUtils-Embed gperftools gperftools-devel gcc -y
wget  http://nginx.org/download/nginx-1.20.1.tar.gz

useradd -u 1111 -s /sbin/nologin www -M

./configure --user=www --group=www  --prefix=/usr/local/nginx/ --with-http_stub_status_module  --with-http_ssl_module  --with-pcre   #如果还有想要加载的模块，可以根据实际情况继续添加
make && make install

cd /usr/local/nginx
./sbin/nginx
netstat -lntup |grep 80

systemctl daemon-reload
systemctl start  nginx

安装nginx（yum最新版本）

yum install -y yum-plugin-priorities   #安装这个插件，给官方源提权
cat /etc/yum.repos.d/nginx.repo
[nginx]
name = nginx repo
baseurl = https://nginx.org/packages/mainline/centos/7/$basearch/
gpgcheck = 0
enabled = 1
priority=1    ##增加优先参数，使得官方源优先epel源。

yum install nginx -y
systemctl start nginx
systemctl enable nginx
systemctl status nginx
