RETVAL=0
prog="Nginx"

start() {
        echo -n $"Starting $prog: "
        mkdir -p /dev/shm/nginx_temp

#保存退出 接下來添加權限
chmod 755 /etc/init.d/nginx
#添加nginx到服務
chkconfig --add nginx
#加到開機自動啓動
chkconfig nginx on

4.配置

#首先把原來的配置文件清空
> /usr/local/nginx/conf/nginx.conf
#編輯
vi /usr/local/nginx/conf/nginx.conf

#加入以下內容
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;


server
        {
            listen 80 default;
            server_name _;
            return 502;
        }
        include /usr/local/nginx/conf/host/*.conf;


}

這裏作了ngnix反向代理,ngnix轉發動態請求到tomcat

server
    {
        listen 80 default;
        server_name 127.0.0.1:8080;
        charset utf-8;
        access_log logs/host.access.log;
        
        location / {
            proxy_pass http://127.0.0.1:8080;
        }
    }
    include /usr/local/nginx/conf/host/*.conf;
}

#檢驗一下配置文件是否有錯誤存在
[root@VM_177_101_centos conf]# /usr/local/nginx/sbin/nginx  -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

#啓動nginx
service nginx start

至此，nginx已經安裝成功，再啓用tomcat,經過ip便可訪問到tomcat歡迎頁面。
