nginx学习笔记(一)

1.与nginx同类的软件

apache  lighttpd tomcat jetty IIS

2.nginx的依赖库

gcc gcc-c++正则库pcrepcre-develzlib zlib-developenssl openssl-devel

默认的安装目录

/usr/local/nginx

修改内核参数

/etc/sysctl.confsysctl -p 使修改后生效

fs.file-max = 999999net.ipv4.tcp_tw_reuse = 1net.ipv4.tcp_keepalive_time = 600net.ipv4.tcp_fin_timeout = 30net.ipv4.tcp_max_tw_buckets = 5000net.ipv4.ip_local_port_range =1024    61000net.ipv4.tcp_rmem =4096 32768 262142net.ipv4.tcp_wmem =4096 32768 262142net.core.netdev_max_backlog = 8096net.core.rmem_default = 262144net.core.wmem_default = 262144net.core.rmem_max = 2097152net.core.rmem_max = 2097152net.ipv4.tcp_syncookies = 1net.ipv4.tcp_max_syn_backlog = 1024

nginx的命令行控制

nginx -g xx nginx -g -s stop➜  init-container git:(master) ✗ nginx -hnginx version: nginx/1.12.0Usage: nginx [-?hvVtTq] [-s signal] [-c filename] [-p prefix] [-g directives]Options:  -?,-h         : this help  -v            : show version and exit  -V            : show version and configure options then exit  -t            : test configuration and exit  -T            : test configuration, dump it and exit  -q            : suppress non-error messages during configuration testing  -s signal     : send signal to a master process: stop, quit, reopen, reload  -p prefix     : set prefix path (default: /usr/local/Cellar/nginx/1.12.0_1/)  -c filename   : set configuration file (default: /usr/local/etc/nginx/nginx.conf)  -g directives : set global directives out of configuration file

nginx配置默认文件

/usr/local/nginx

配置的通用语法

➜  ~ cat /usr/local/etc/nginx/nginx.conf#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       9990;        server_name  localhost;        #charset koi8-r;        #access_log  logs/host.access.log  main;        location / {            root /usr/local/var/www/metronic.bootstrap;            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 {            root   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        #        #location ~ \.php$ {        #    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    #    #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;    #    location / {    #        root   html;    #        index  index.html index.htm;    #    }    #}    include servers/*;}
