安装nginx

首先需要安装pcre库

1.下载安装包 wget    

2.解压  tar -zxvf pcre-8.40.tar.gz

3.进入安装包目录 cd pcre-8.40

4.编译安装./configure

make && make install

5.查看PCRE版本pcre-config --version

安装nginx

1.下载安装包 wget

2.解压  tar -zxvf nginx-1.14.0.tar.gz

3.切换到安装目录cd nginx-1.14.0

4../configure --prefix=/root/data/nginx1 后面跟的路径是它的安装路径

5.echo $?

6.make && make install

7.echo $?

8.cd /root/data/nginx1/

9.ls  # 安装完成

conf  html  logs  sbin

创建nginx的主配置文件，因为我们不使用nginx自带的配置文件：

1.mv nginx.conf nginx.conf.bak  ##对配置文件进行备份

2.vim nginx.conf  # 内容如下

user nobody nobody;

worker_processes 2;

error_log /root/data/nginx1/logs/nginx_error.log crit;

pid /root/data/nginx1/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 /root/data/nginx1/client_body_temp;

    proxy_temp_path /root/data/nginx1/proxy_temp;

    fastcgi_temp_path /root/data/nginx1/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;

    add_header Access-Control-Allow-Origin *;

    include vhost/*.conf;

}

3.mkdir vhost  # 创建虚拟主机配置文件的存放目录

4.cd vhost

5.vim   # 创建虚拟主机配置文件，内容如下：

upstream 192.168.204.134{

        # 需要负载的server列表，可以直接使用ip

        server 192.168.204.134:9999 weight=1;

        server 192.168.204.134:9080 weight=3;

        # server weight=1;

        # server weight=3;

}

 

server{

  listen 80;

  autoindex on;

  server_name 192.168.204;

  access_log /root/data/nginx1/logs/access.log combined;

  index index.html index.htm index.jsp;

 

  location / {

        proxy_pass

        add_header Access-Control-Allow-Origin *;

  }

}

3.检查nginx配置文件，显示没问题则启动nginx服务：

1.cd /root/data/nginx1/sbin

2. ./nginx -t  # 检查nginx配置文件

nginx: the configuration file /root/data/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /root/data/nginx/conf/nginx.conf test is successful

3../nginx -c /root/data/nginx1/conf/nginx.conf  # 启动nginx服务

4.netstat -lntp | grep nginx  # 检查端口是否已监听

5.ps aux |grep nginx  # 检查nginx进程是否正常
