Nginx Echo模块使用

admin

1. #查看Nginx编译模块:
   
2. /usr/local/nginx/sbin/nginx -V
   
3. --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_random_index_module --with-http_sub_module
   
4. 
   
5. #安装Echo模块:
   
6. unzip echo-nginx-module-master.zip
   
7. 
   
8. #给Nginx动态增加Echo模块:
   
9. ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_random_index_module --with-http_sub_module --add-module=/mnt/echo-nginx-module-master
   
10. 
    
11. #把Nginx重新编译:
    
12. make
    
13. 
    
14. #让新Nginx程序生效:
    
15. pkill nginx
    
16. cp /mnt/nginx-1.17.5/objs/nginx /usr/local/nginx/sbin/
    
17. 
    
18. #重新启动Nginx:
    
19. /usr/local/nginx/sbin/nginx
    
20. 
    
21. #Echo模块测试:
    
22. location /test {
    
23.         echo "user123";
    
24. }
    
25. 
    
26. #Echo输出内置变量:
    
27. location /test {
    
28.         echo $remote_addr;
    
29. }
    
30. 
    
31. #变量定义与输出:
    
32. location /test {
    
33.         set $name user123;
    
34.         echo $name;
    
35. }
    
36. 
    
37. #异步执行多location:
    
38. location /echo1 {
    
39.     echo_sleep 1;
    
40.     echo '111';
    
41. }
    
42. 
    
43. location /echo2 {
    
44.     echo_sleep 1;
    
45.     echo '222';
    
46. }
    
47. 
    
48. location /main {
    
49.       echo_reset_timer;
    
50. 
    
51.       echo_location_async /echo1;
    
52.       echo_location_async /echo2;
    
53. 
    
54.       echo "took $echo_timer_elapsed sec for total.";
    
55. }
    
56. 
    
57. #同步执行多location:
    
58. location /echo1 {
    
59.     echo_sleep 1;
    
60.     echo '111';
    
61. }
    
62. 
    
63. location /echo2 {
    
64.     echo_sleep 2;
    
65.     echo '222';
    
66. }
    
67. 
    
68. location /main {

70. 
    
71.       echo_location /echo1;

73. 
    
74.       echo "took $echo_timer_elapsed sec for total.";
    
75. }
    
76. 
    
77. #echo_duplicate重复多次输出:
    
78. location /echo3 {
    
79.     echo_duplicate 10 "hello ";
    
80. }
