记录一次nginx启动失败的解决过程

PHP小丑

小编最近遇到这样一个问题docker nginx起不来了，导致jira域名映射失败，如何解决呢？下面小编给大家分享下nginx启动失败的解决过程，感兴趣的朋友一起看看吧
周日领导说docker nginx起不来了，导致jira域名映射失败，记录一下解决过程
操作
首先nginx不是自己部署，要先启动一下

docker start nginx

发现打印出了nginx 但是 docker ps 发现 nginx还是启动失败
于是准备查看日志

docker logs -f nginx

报了一堆错误，也不知道是什么时候打的日志，后来解决之后猜测是因为配置文件为空的原因，因为没有找到event模块
所以首先看一下nginx的容器信息

docker inspect nginx

找到挂载信息了，可以看看配置文件，发现 /usr/nginx/conf 里面没有配置文件，这个时候就应该找到了问题；可是运维同学在查询问题的时候创建了一个空的nginx.conf，我没有打开配置文件
后来在老大的提醒下打开了配置文件发现是空的，然后就对配置文件进行了修改
先找了一个默认的nginx.conf的配置

#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 {
    # 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
    #  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
  #  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;

然后docker start nginx 发现可以启动了
接下来增加正确的jira配置

location / {
   proxy_pass http://192.168.1.111:8080;
  proxy_redirect      off;  
         proxy_set_header    Host $host:$server_port;   ##重点在$server_port
         proxy_set_header    X-Real-IP $remote_addr;
         proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_max_temp_file_size 0;
         proxy_connect_timeout 90;
         proxy_send_timeout 90;
         proxy_read_timeout 90;
         proxy_buffer_size 4k;
         proxy_buffers 4 32k;
         proxy_busy_buffers_size 64k;
         proxy_hide_header Vary;
         proxy_set_header Accept-Encoding '';
         proxy_set_header Referer $http_referer;
         proxy_set_header Cookie $http_cookie;
     }

进入容器检测一下配置文件是否有问题

docker exec -it 容器id /bin/bash

nginx路径寻找 find / -name nginx

./nginx/sbin/nginx -t

检测发现少了一个}

:set nu

找到具体行，然后修复

ctrl +D  // 退出容器

启动nginx

docker restart nginx

结果
虽然解决的很慢 但是还是解决了问题，nginx单点也是有问题的，后期打算切换到多活的nginx，然后备份相关nginx文件
