# 1、uuid生成方法一 #

openresty官网:[http://openresty.org/cn/download.html][http_openresty.org_cn_download.html]  
Luajit官网：https://luajit.org  
环境准备

yum install pcre-devel openssl-devel gcc curl wget -y

下载资源  
\[root@i-0vjkl1ko ~\]\# mkdir -p /soft      
\[root@i-0vjkl1ko ~\]\# cd /soft  
\[root@i-0vjkl1ko soft\]\# wget https://openresty.org/download/openresty-1.13.6.2.tar.gz  
\[root@i-0vjkl1ko soft\]\# tar  -zxvf openresty-1.13.6.2.tar.gz

\[root@i-0vjkl1ko soft\]\# cd openresty-1.13.6.2

然后在进入openresty-1.13.6.2`/` 目录, 然后输入以下命令配置:

./configure

默认, `--prefix=/usr/local/openresty` 程序会被安装到/usr/local/openresty目录。

您可以指定各种选项，比如

./configure --prefix=/opt/openresty \
                --with-luajit \
                --without-http_redis2_module \
                --with-http_iconv_module \
                --with-http_postgres_module

试着使用 `./configure --help` 查看更多的选项。

编译：

make

编译没问题后再安装：

make install

添加环境变量

PATH=/usr/local/openresty/nginx/sbin:$PATH

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d1MjcwMDIyMg_size_16_color_FFFFFF_t_70 2][]

然后保存

source /etc/profile

通过输入env可查看所以环境变量设置

输入 nginx -v查看版本

\[root@i-0vjkl1ko local\]\# nginx -v  
nginx version: openresty/1.13.6.2

启动openresty

nginx

重启openresty

nginx -s reload

注意openresty中的nginx的文件信息如下：

日志和pid：/usr/local/openresty/nginx/logs

配置文件:   /usr/local/openresty/nginx/conf/nginx.conf

测试例子1，返回hello world：

vim  /usr/local/openresty/nginx/conf/nginx.conf  添加

server {
 listen 8080;
 location / {
 default_type text/html;
 content_by_lua '
 ngx.say("hello, world")
 ';
 }
 }

重启生效 nginx -s reload

执行访问测试，正确返回hello world

\[root@i-0vjkl1ko conf\]\# curl http://localhost:8080/ 
hello, world

例子2，调用lua脚本，获取uuid

mkdir /usr/local/openresty/nginx/lua

vim /usr/local/openresty/nginx/lua/uuid

function guid()
        local seed = {
                '0','1','2','3','4','5','6','7','8','9',
                'a','b','c','d','e','f','g','h','i','j',
                'k','l','m','n','o','p','q','r','s','t',
                'u','v','w','x','y','z'
        }
    
        local sid = ""
        for i=1, 32 do
            sid = sid .. seed[math.random(1,36)]
        end
    
        return string.format('%s-%s-%s-%s-%s',
            string.sub(sid, 1, 8),
            string.sub(sid, 9, 12),
            string.sub(sid, 13, 16),
            string.sub(sid, 17, 20),
            string.sub(sid, 21, 32)
        )
    end
    
    return guid()

vim /usr/local/openresty/nginx/conf/nginx.conf

在http中新增以下server

server {
            listen 8082;
    
            location / {
                set_by_lua_file $res /usr/local/openresty/nginx/lua/uuid.lua;
                echo $res;
            }
        }

nginx -s reload

执行测试 curl

\[root@i-0vjkl1ko nginx\]\# curl http://localhost:8082                        
splr2ncq-fk41-zp6z-9cho-ksg6n7l5tk0u

ok，大公告成

下面是我对nginx中链路的理解参数

nginx.conf配置如下：

#user nobody;

 #error_log logs/error.log notice;

 }

请求

\[root@i-0vjkl1ko nginx\]\# curl http://localhost:8082                     
hello, world

![20190321181554184.png][]

time\_iso8601 和 msec 记录的是写入日志的时间

请求从8082发起，中间80端口，最后才是8080,但写入日志的时间刚好相反，是因为最开始的请求是最后写入的要统计响应时间和流量大小等。

设置openresty开机自启动

echo '/usr/local/openresty/nginx/sbin/nginx' >> /etc/rc.local

chmod +x /etc/rc.local

ok,reboot测试一下吧

# 二、uuid生成方法二 #

注意标红这部分的写法，if后面要加空格，=左右也要加，注意nginx没有else写法，所有2个if

server \{  
        listen 80;  
        charset utf-8;  
        default\_type  text/html;

server\_name dev-qll.otosaas.com;

location ^~ / \{  
            proxy\_redirect   off;  
            proxy\_set\_header Host            $host;  
            proxy\_set\_header X-Real-Ip       $remote\_addr;  
            proxy\_set\_header X-Forwarded-for $remote\_addr;

if ( $http\_rid = '' )\{  
            set $uuid $request\_id;  
        \}

if ( $http\_rid != '' )\{  
            set $uuid $http\_rid;  
        \}

proxy\_set\_header rid  $uuid;

proxy\_pass http://127.0.0.1:8080;  
            add\_header  'Access-Control-Allow-Origin' '\*';  
            add\_header  'Access-Control-Allow-Cerdentials' 'true';  
            add\_header  'Access-Control-Allow-Methods' 'OPTIONS,POST,GET';  
            add\_header  'Access-Control-Allow-Headers' 'rid';  
        \}  
    \}
