4.配置
#首先把原来的配置文件清空> /usr/local/nginx/conf/nginx.conf#编辑vi /usr/local/nginx/conf/nginx.conf#加入如下内容user nobody nobody;worker_processes 2;error_log /usr/local/nginx/logs/nginx_error.log crit;pid /usr/local/nginx/logs/nginx.pid;worker_rlimit_nofile 51200;events{use epoll;worker_connections 6000;}http{include mime.types;default_type application/octet-stream;server_names_hash_bucket_size 3526;server_names_hash_max_size 4096;log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]''$host "$request_uri" $status''"$http_referer" "$http_user_agent"';sendfile on;tcp_nopush on;keepalive_timeout 30;client_header_timeout 3m;client_body_timeout 3m;send_timeout 3m;connection_pool_size 256;client_header_buffer_size 1k;large_client_header_buffers 8 4k;request_pool_size 4k;output_buffers 4 32k;postpone_output 1460;client_max_body_size 10m;client_body_buffer_size 256k;client_body_temp_path /usr/local/nginx/client_body_temp;proxy_temp_path /usr/local/nginx/proxy_temp;fastcgi_temp_path /usr/local/nginx/fastcgi_temp;fastcgi_intercept_errors on;tcp_nodelay on;gzip on;gzip_min_length 1k;gzip_buffers 4 8k;gzip_comp_level 5;gzip_http_version 1.1;gzip_types text/plain application/x-javascript text/css text/htm application/xml;#加载其他目录的nginx配置文件include /etc/nginx/conf/*.conf;server {listen 80 default_server;listen [::]:80 default_server;server_name _;root /usr/share/nginx/html;# Load configurat:ion files for the default server block.include /usr/local/nginx/default.d/*.conf;location / {}error_page 404 /404.html;location = /404.html {}error_page 500 502 503 504 /50x.html;location = /50x.html {}}}
5 启动服务
#检验一下配置文件是否有错误存在/usr/local/nginx/sbin/nginx -t#启动nginxservice nginx start#配置环境变量vim /etc/profile修改(增加)path 多个用:分割
让环境变量生效source /etc/profile#启动nginxservice nginx start
