## 前言
续上一篇,记录的是编译源码方式,安装 OpenResty
[OpenResty 安装配置入门教程 代替Nginx 使用lua redis动态控制请求](https://leanote.zzzmh.cn/blog/post/admin/60d2e8f816199b501c026ab5)
<br>
本篇用更简单的yum方式安装,且支持后续更新,所需插件和模块也会一并自动安装
<br>
默认是不支持 `brotli` ,我这里选择直接去掉 `brotli` ,只用 `gzip` ,影响不大

## 折腾
基于官网教程
[http://openresty.org/cn/linux-packages.html#centos](http://openresty.org/cn/linux-packages.html#centos)
```shell
# 以下命令适用于 CentOS 7
# (对于 CentOS 8 或以上版本,应将下面的 yum 都替换成 dnf)
wget https://openresty.org/package/centos/openresty.repo
sudo mv openresty.repo /etc/yum.repos.d/
sudo yum check-update
yum install -y openresty
# 启动和开机启动
systemctl start openresty
systemctl enable openresty
```
<br>
安装细节同样可以参考官网
[http://openresty.org/cn/rpm-packages.html](http://openresty.org/cn/rpm-packages.html)
只需关注几个重点
```shell
# 安装路径
/usr/bin/openresty
# nginx 配置文件路径
/usr/local/openresty/nginx/conf/nginx.conf
# 常用命令
# 启动 重启 停止 状态 开机启动
systemctl start openresty
systemctl restart openresty
systemctl stop openresty
systemctl status openresty
systemctl enable openresty
# 帮助 测试配置文件
openresty -h
openresty -t
# 同nginx 重新加载配置文件
openresty -s reload
```
配置文件调试
默认路径
`/usr/local/openresty/nginx/conf/nginx.conf`
```shell
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
```
例如开启tls3
```shell
server {
listen 443 ssl http2 default_server;
server_name xxx.com;
# 证书部分
ssl_certificate /root/ssl/xxx.crt;
ssl_certificate_key /root/ssl/xxx.key;
# TLS 握手优化
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 5m;
keepalive_timeout 75s;
keepalive_requests 100;
# TLS 版本控制
ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
ssl_ciphers 'TLS13-AES-256-GCM-SHA384:TLS13-CHACHA20-POLY1305-SHA256:TLS13-AES-128-GCM-SHA256:TLS13-AES-128-CCM-8-SHA256:TLS13-AES-128-CCM-SHA256:EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+ECDSA+AES128:EECDH+aRSA+AES128:RSA+AES128:EECDH+ECDSA+AES256:EECDH+aRSA+AES256:RSA+AES256:EECDH+ECDSA+3DES:EECDH+aRSA+3DES:RSA+3DES:!MD5';
# 开启 1.3 o-RTT
ssl_early_data on;
location / {
...
}
...
}
```
