Nginx

Linux常用命令

显示系统相关信息

uname -a

查看端口占用情况

查看全部

netstat -tanlp

筛 选

netstat -tanlp | grep 8080

杀掉进程

kill -9 PID

防火墙

查看firewall服务状态

systemctl status firewalld

开启、重启、关闭、firewalld.service服务

开启

service firewalld start

关闭

service firewalld stop

重启

service firewalld restart

查看防火墙规则

查看全部信息

firewall-cmd --list-all

只看端口信息

firewall-cmd --list-ports

开端口命令

firewall-cmd --zone=public --add-port=80/tcp --permanent

含义：--zone #作用域 --add-port=80/tcp #添加端口，格式为：端口/通讯协议 --permanent #永久生效，没有此参数重启后失效

重启防火墙

systemctl restart firewalld.service

查找

find / -name mysql # 查找名字为mysql的相关文件

介绍

Nginx (engine x) 是一个高性能的HTTP和反向代理服务器。

特点：占有内存少，并发能力强。

Linux安装

安装

下载Nginx

https://nginx.org/en/download.html

解压安装包

tar -zxvf nginx-1.20.1.tar.gz

安装gcc

yum install gcc-c++

进入nginx目录

执行 ./configure

报错

执行 yum install -y pcre-devel

报错

执行 yum install -y zlib-devel

执行 make

执行 make install

Nginx常用命令

使用nginx操作命令的前提，要进入到nginx的目录中去

/usr/local/nginx/sbin

查看nginx版本号

./nginx -v

关闭nginx

./nginx -s stop

启动nginx

./nginx

重新加载nginx

./nginx -s reload

nginx配制文件

位置

/usr/local/nginx/conf

全局快

从配置文件开始到events块之间的内容，主要会设置一些影响nginx服务器整体运行的配置指令。

events块

events主要影响nginx服务器与用户的网络连接。

http块

nginx配置最频繁的部分，http块包含 http全局快、server块。

配制文件

#user nobody; worker_processes 1; # 值越大，可以支持的并发处理量也就越多 #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; # 支持的最大连接数 } 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 8888; server_name 8.140.157.45; #charset koi8-r; #access_log logs/host.access.log main; #location / { # root html; # index index.html index.htm; #} location ~ /eduservice/ { proxy_pass http://localhost:8001; } location ~ /user/ { proxy_pass http://localhost:8001; } location ~ /eduoss/ { proxy_pass http://localhost:8002; } #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; # } #} }
