常用版本分为四大阵营
Nginx开源版 nginx.org/
Nginx plus 商业版 www.nginx.com
openresty openresty.org/cn/
Tengine tengine.taobao.org/
这里使用Nginx开源版的源码包，进行编译安装。
1.1 源码包编译安装
1.1.1 编译安装
./configure --prefix=/usr/local/nginx
make
make install
如果出现警告或报错
提示
checking for OS + Linux 3.10.0-693.el7.x86_64 x86_64 checking for C compiler ... not found
./configure: error: C compiler cc is not found
安装gcc
yum install -y gcc
提示： ./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module option, or install the PCRE library into the system, or build the PCRE library statically from the source with nginx by using --with-pcre= option.
安装perl库
yum install -y pcre pcre-devel
提示：
./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module option, or install the zlib library into the system, or build the zlib library statically from the source with nginx by using --with-zlib= option.
安装zlib库
yum install -y zlib zlib-devel
接下来执行
make
make install
1.1.2 启动Nginx
进入安装好的目录 /usr/local/nginx/sbin
./nginx 启动
./nginx -s stop 快速停止
./nginx -s quit 优雅关闭，在退出前完成已经接受的连接请求
./nginx -s reload 重新加载配置
1.1.3 配置防火墙
关闭防火墙
systemctl stop firewalld.service
禁止防火墙开机启动
systemctl disable firewalld.service
放行端口
firewall-cmd --zone=public --add-port=80/tcp --permanent
重启防火墙
firewall-cmd --reload
1.1.4 安装成系统服务
创建服务脚本
vi /usr/lib/systemd/system/nginx.service
