nginx: [emerg] unknown directive "echo" 

問題現象：

#nginx -t
nginx: [emerg] unknown directive "echo" in /apps/nginx-1.18.0/conf.d/p.conf:24
nginx: configuration file /apps/nginx-1.18.0/conf/nginx.conf test failed

原因缺少echo 模組,需重新編譯解決

#cd /apps/nginx-1.18.0
#yum -y install git
#git clone https://github.com/openresty/echo-nginx-module.git
 

#./configure --prefix=/apps/nginx-1.18.0 --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream --with-stream_ssl_module --with-stream_realip_module --add-module=/apps/nginx-1.18.0/echo-nginx-module

#make -j 2 && make install
#nginx -t
nginx: the configuration file /apps/nginx-1.18.0/conf/nginx.conf syntax is ok
nginx: configuration file /apps/nginx-1.18.0/conf/nginx.conf test is successful

測試驗證

#systemctl daemon-reload
#systemctl restart nginx

#curl mp.weirui.vip/main -L
hello world,main-->
10.0.0.117
sub1
sub2
took 2.011 sec for total.

配置如下

#cat /apps/nginx-1.18.0/conf.d/p.conf
server {
        listen       80;
        root /apps/nginx-1.18.0/html;

        location / {
            stub_status;

        }
        location /main {
            index index.html;
            default_type text/html;
            echo "hello world,main-->";
            echo $remote_addr ;
            echo_reset_timer;
            echo_location /sub1;
            echo_location /sub2;
            echo "took $echo_timer_elapsed sec for total.";
        }
        location /sub1 {
            echo_sleep 1;
            echo sub1;
        }
        location /sub2 {
            echo_sleep 1;
            echo sub2;
        }
}
