1、安装、启动nginx

    1. yum install nginx
    3. systemctl start nginx

    2、更改配置文件 /etc/nginx/nginx.conf

    1. user nginx nginx;
    2. worker_processes auto;
    4. error_log  /var/log/nginx/error.log warn;
    5. pid        /var/run/nginx.pid;
    7. events {
    8.     worker_connections 65000;
    9. }
    11. http {
    12.     include       /etc/nginx/mime.types;
    13.     default_type  application/octet-stream;
    15.     log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    16.                       '$status $body_bytes_sent "$http_referer" '
    17.                       '"$http_user_agent" "$http_x_forwarded_for"';
    19.     client_body_buffer_size 1024m;
    20.     #access_log off;
    21.     access_log  /var/log/nginx/access.log  main;
    22.     server_tokens off;
    23.     sendfile on;
    24.     tcp_nopush on;
    25.     tcp_nodelay on;
    27.     keepalive_timeout 10;
    28.     client_header_timeout 10;
    29.     client_body_timeout 10;
    30.     reset_timedout_connection on;
    31.     send_timeout 10;
    33.     limit_conn_zone $binary_remote_addr zone=addr:5000m;
    34.     limit_conn addr 65535;
    35.     #client_max_body_size 1000m;
    37.     charset UTF-8;
    39.     gzip on;
    40.     gzip_disable "msie6";
    41.     gzip_proxied any;
    42.     gzip_min_length 1000;
    43.     gzip_comp_level 9;
    44.     gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
    46.     open_file_cache max=100000 inactive=20s;
    47.     open_file_cache_valid 30s;
    48.     open_file_cache_min_uses 2;
    49.     open_file_cache_errors on;
    51.     include /etc/nginx/conf.d/*.conf;
    52. }

    配置fastcgi参数 /etc/nginx/fastcgi_params 

    2. fastcgi_param  QUERY_STRING       $query_string;
    3. fastcgi_param  REQUEST_METHOD     $request_method;
    4. fastcgi_param  CONTENT_TYPE       $content_type;
    5. fastcgi_param  CONTENT_LENGTH     $content_length;
    7. fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
    8. fastcgi_param  REQUEST_URI        $request_uri;
    9. fastcgi_param  DOCUMENT_URI       $document_uri;
    10. fastcgi_param  DOCUMENT_ROOT      $document_root;
    11. fastcgi_param  SERVER_PROTOCOL    $server_protocol;
    12. fastcgi_param  REQUEST_SCHEME     $scheme;
    13. fastcgi_param  HTTPS              $https if_not_empty;
    15. fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
    16. fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;
    18. fastcgi_param  REMOTE_ADDR        $remote_addr;
    19. fastcgi_param  REMOTE_PORT        $remote_port;
    20. fastcgi_param  SERVER_ADDR        $server_addr;
    21. fastcgi_param  SERVER_PORT        $server_port;
    22. fastcgi_param  SERVER_NAME        $server_name;
    24. # PHP only, required if PHP was built with --enable-force-cgi-redirect
    25. fastcgi_param  REDIRECT_STATUS    200;
    27. fastcgi_buffer_size 256M;
    28. fastcgi_buffers 4 256M;
    29. fastcgi_busy_buffers_size 256M;
    30. fastcgi_connect_timeout 300s;
    31. fastcgi_send_timeout 300s;
    32. fastcgi_read_timeout 300s;
    34. fastcgi_intercept_errors on;
    35. fastcgi_max_temp_file_size 0;
    36. fastcgi_pass  unix:/dev/shm/php-fpm.sock;
    37. fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

    fastcgi_pass 表示使用哪个代理
    可以使用php-fpm的 127.0.0.1:9000

    配置网站 /etc/nginx/conf.d/test.conf

    1. server {
    2.     listen       80 8080;
    3.     server_name  test.com xyz.com;
    4.     #access_log  off;
    5.     index index.php;
    6.     error_page 502 = /502.html;
    7.     error_page 404 = /404.html;
    8.     root  /opt/app/public;
    10.     if (!-e $request_filename) {
    11.          rewrite  ^(.*)$  /index.php?s=$1  last;
    12.          break;
    13.     }
    15.     location ~ .*\.php?$
    16.     {
    17.         include fastcgi_params;
    18.         fastcgi_param channel $http_channel;
    19.         fastcgi_index index.php;
    20.     }
    21. }

    启动报错 以及解决方法

    1. #报错 1 配置内存不足
    2. nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
    3. nginx: [alert] mmap(MAP_ANON|MAP_SHARED, 5242880000) failed (12: Cannot allocate memory)
    4. nginx: configuration file /etc/nginx/nginx.conf test failed.
    7. zone限制内存
    8. limit_conn_zone $binary_remote_addr zone=addr:500m;

    15. #报错 2 绑定端口拒绝
    16. bind() to 0.0.0.0:8880 failed (13: Permission denied)
    18. #权限拒绝，经检查发现是开启selinux 导致的。 直接关闭
    19. #getenforce   这个命令可以查看当前是否开启了selinux 如果输出 disabled 或 permissive 那就是关闭了
    20. #如果输出 enforcing 那就是开启了 selinux
    21. #1、临时关闭selinux
    22. #setenforce 0    ##设置SELinux 成为permissive模式
    23. #setenforce 1    ##设置SELinux 成为enforcing模式
    24. #2、永久关闭selinux,
    25. #修改/etc/selinux/config 文件
    26. #将SELINUX=enforcing改为SELINUX=disabled
    27. #重启机器即可
