1、Nginx簡介
Nginx
是一個輕量級高性能的HTTP和反向代理的Web伺服器。特點:占有記憶體少、并發能力強。
2、Nginx的安裝
Nginx官網
2.1、Windows下
下載下傳對應的版本、下載下傳後直接解壓
2.2、Linux下
(1)、安裝前準備
#安裝依賴:
sudo yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel
(2)、下載下傳Nginx包,可官網下載下傳也可利用wget下載下傳
#cd 進入下載下傳包的路徑、這裡使用的/opt/soft
#在opt下建立soft
mkdir -p /opt/soft
# 進入到soft檔案夾
cd /opt/soft
#下載下傳nginx安裝包
sudo wget http://nginx.org/download/nginx-1.18.0.tar.gz
# 如果提示sudo: wget:找不到指令,先安裝wget
sudo yum install wget
#解壓
sudo tar -zxvf nginx-1.18.0.tar.gz
#進入nginx-1.18.0目錄
sudo cd nginx-1.18.0
#執行指令并編譯
sudo ./configure
sudo make
sudo make install
3、nginx的配置
cd /usr/local/nginx/conf/
預設配置檔案說明
#user nobody;
#啟動程序,通常設定成和cpu的數量相等
worker_processes 1;
#工作模式及連接配接數上限
events {
#單個背景worker process程序的最大并發連結數
worker_connections 1024;
}
#設定http伺服器,利用它的反向代理功能提供負載均衡支援
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;
#指令指定 nginx 是否調用 sendfile 函數(zero copy 方式)來輸出檔案,對于普通應 #用,必須設為 on,如果用來進行下載下傳等應用磁盤IO重負載應用,可設定為 off,以平衡磁盤
#與網絡#I/O處理速度,降低系統的uptime.
sendfile on;
#tcp_nopush on;
#連接配接逾時時間
#keepalive_timeout 0;
keepalive_timeout 65;
#開啟gzip壓縮
#gzip on;
#伺服器相關配置
server {
#偵聽80端口
listen 80;
#定義使用www.xx.com通路
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
#預設請求
location / {
root html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
# 定義錯誤提示頁面
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;
# }
#}
4、nginx常用指令
#進入到nginx的sbin目錄下
cd /usr/local/nginx/sbin
#指令
#啟動
./nginx
#重新加載配置檔案
./nginx -s reload
#檢視nginx程序
ps aux | grep nginx 檢視nginx程序
#停止(強制的)
./nginx -s stop
#安全退出(線程一個個關閉)
./nginx -s quit
5、檢視是否安裝成功
浏覽器輸入ip位址,出現以下界面表示安裝成功
