记录一次nginx启动失败的解决过程

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 Apaches document root # concurs with nginxs 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
