准备篇
一、防火墙配置
CentOS 8.x默认使用的是firewall作为防火墙，这里改为iptables防火墙。
1、关闭firewall：
systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动
systemctl mask firewalld
systemctl stop firewalld
yum remove firewalld
2、安装iptables防火墙
yum install iptables-services #安装
vi /etc/sysconfig/iptables #编辑防火墙配置文件
# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 443 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
:wq! #保存退出
systemctl restart iptables.service #最后重启防火墙使配置生效
systemctl enable iptables.service #设置防火墙开机启动
/usr/libexec/iptables/iptables.init restart #重启防火墙
二、关闭SELINUX
vi /etc/selinux/config
#SELINUX=enforcing #注释掉
#SELINUXTYPE=targeted #注释掉
SELINUX=disabled #增加
:wq! #保存退出
setenforce 0 #使配置立即生效
三 、系统约定
软件源代码包存放位置：/usr/local/src
源码包编译安装位置：/usr/local/openresty
四、下载软件包
1、下载openresty
https://openresty.org/download/openresty-1.21.4.1.tar.gz
2、下载pcre（支持openresty伪静态）
http://ftp.cs.stanford.edu/pub/exim/pcre/pcre-8.45.tar.gz
3、下载openssl（openresty扩展）
https://www.openssl.org/source/openssl-1.1.1o.tar.gz
4、下载zlib（openresty扩展）
http://www.zlib.net/zlib-1.2.12.tar.gz
五、安装编译工具及库文件（使用yum命令安装）
yum install apr* autoconf automake bison bzip2 bzip2* cpp curl curl-devel fontconfig fontconfig-devel freetype-devel google-perftools-devel GeoIP-devel git gcc gcc-c++ gd gd-devel gettext gettext-devel glibc kernel kernel-headers keyutils keyutils-libs-devel krb5-devel libcom_err-devel libpng libpng-devel libjpeg* libsepol-devel libselinux-devel libstdc++-devel libunwind-devel libtool* libgomp libxml2 libxml2-devel libXpm* libxml* libXaw-devel libXmu-devel libtiff libtiff* make openssl openssl-devel patch pcre-devel perl php-common php-gd policycoreutils telnet wget zlib-devel ncurses-devel libtirpc-devel gtk* ntpstat bison* sqlite-devel oniguruma libzip-devel
安装篇
安装OpenResty
1、安装pcre
cd /usr/local/src
mkdir /usr/local/pcre
tar zxvf pcre-8.45.tar.gz
cd pcre-8.45
./configure --prefix=/usr/local/pcre
make
make install
2、安装openssl
cd /usr/local/src
mkdir /usr/local/openssl
tar zxvf openssl-1.1.1o.tar.gz
cd openssl-1.1.1o
./config -fPIC shared zlib --prefix=/usr/local/openssl
make
make install
3、安装zlib
cd /usr/local/src
mkdir /usr/local/zlib
tar zxvf zlib-1.2.12.tar.gz
cd zlib-1.2.12
./configure --prefix=/usr/local/zlib
make
make install
4、安装OpenResty
groupadd www
useradd -g www www -s /bin/false
cd /usr/local/src
tar zxvf openresty-1.21.4.1.tar.gz
cd openresty-1.21.4.1
./configure --prefix=/usr/local/openresty --without-http_memcached_module --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-http_v2_module --with-luajit --with-pcre-jit --with-http_realip_module --with-http_geoip_module --with-openssl=/usr/local/src/openssl-1.1.1o --with-zlib=/usr/local/src/zlib-1.2.12 --with-pcre=/usr/local/src/pcre-8.45
注意：--with-openssl=/usr/local/src/openssl-1.1.1o --with-zlib=/usr/local/src/zlib-1.2.12 --with-pcre=/usr/local/src/pcre-8.45指向的是源码包解压的路径，而不是安装的路径，否则会报错
gmake
gmake install
#启动OpenResty
/usr/local/openresty/nginx/sbin/nginx
/usr/local/openresty/bin/openresty
#关闭OpenResty
ps -ef | grep nginx
kill -QUIT 1069
kill -TERM 1069
kill -9 nginx
#设置OpenResty开机启动
vi /lib/systemd/system/openresty.service #添加以下代码
[Unit]

[Install]
WantedBy=multi-user.target
:wq! #保存退出
/usr/local/openresty/nginx/sbin/nginx -s stop #停止
systemctl enable openresty.service #设置开机自启动
systemctl start openresty.service #启动
systemctl stop openresty.service #关闭
systemctl restart openresty.service #重启
systemctl reload openresty.service #重新加载配置文件
至此，Linux下编译安装OpenResty完成。
扩展阅读：
OpenResty配置txt、pdf、doc、xls等文件直接下载的方法
在nginx配置文件/usr/local/openresty/nginx/conf/nginx.conf中添加以下代码
location / {
if ($request_filename ~* ^.*?\.(txt|pdf|doc|xls)$){
add_header Content-Disposition: 'attachment;';
}
}
