1. nginx安裝

    注：yum安裝過程中如果報錯except IOError, e invalid syntax並且重新安裝了python3，那麼是因為當前yum不支援python3，解決方案1：升級yum；2：修改/usr/bin/yum檔案的開頭改為#! /usr/bin/python2

yum install gcc-c++
yum install -y pcre pcre-devel
yum install -y zlib zlib-devel
yum install -y openssl openssl-devel

wget -c https://nginx.org/download/nginx-1.12.0.tar.gz
 

tar -zxvf nginx-1.12.0.tar.gz
cd nginx-1.12.0
./configure
make && make install
# 檢視安裝位置
whereis nginx
# 測試配置檔案並檢查配置檔案 
nginx -t

如果報錯error while loading shared libraries: libgd.so.2: cannot open shared object，需要安裝libgd

yum install gd

當執行

nginx -t

出現

nginx: the configuration file /www/server/nginx/conf/nginx.conf syntax is ok
nginx: configuration 
 
file /www/server/nginx/conf/nginx.conf test is successful

說明安裝成功。

2. 配置conf檔案

vi /www/server/nginx/conf/nginx.conf

user  www www;
worker_processes auto;
error_log  /www/wwwlogs/nginx_error.log  crit;
pid        /www/server/nginx/logs/nginx.pid;

events
    {
        use epoll;
        worker_connections 
 
51200;
        multi_accept on;
    }
http
    {
        include       mime.types;
                #include luawaf.conf;
                include proxy.conf;

        tcp_nodelay on;
        fastcgi_connect_timeout 300;
        fastcgi_send_timeout 300;
        fastcgi_read_timeout 300;
        fastcgi_buffer_size 64k;
        fastcgi_buffers 4 64k;
        fastcgi_busy_buffers_size 128k;
        fastcgi_temp_file_write_size 256k;
                fastcgi_intercept_errors on;
        gzip on;
        gzip_min_length  1k;
        gzip_buffers     4 16k;
        gzip_http_version 1.1;
        gzip_comp_level 2;
        gzip_types     text/plain application/javascript application/x-javascript text/javascript text/css application/xml;
        gzip_vary on;

        gzip_disable   "MSIE [1-6]\.";
        limit_conn_zone $binary_remote_addr zone=perip:10m;
                limit_conn_zone $server_name zone=perserver:10m;
        server_tokens off;
        access_log off;
