  • centos安装nginx

    1、编译环境gcc g++ 开发库之类的需要提前装好

      yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

    2、首先安装PCRE  pcre功能是让nginx有rewrite功能

      

      2.1 先检查系统里是否安装了pcre软件

      rpm -qa pcre   如果没有显示说明没有安装  反之安装过

      rpm -e --nodeps pcre  删除pcre

      

      2.2 下载PCRE:wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

      解压安装包:tar zxvf pcre-8.35.tar.gz

      进入安装包目录:cd pcre-8.35

      编译:./configure

      安装:make && make install

      查看安装版本:pcre-config --version   如果出现版本号,说明安装成功

      

      

    3、安装nginx

      下载nginx:wget http://nginx.org/download/nginx-1.6.2.tar.gz

      解压安装包: tar zxvf nginx-1.6.2.tar.gz

      进入安装包目录:cd nginx-1.6.2

      编译安装:./configure

      安装:make

      安装:make install  

      注:

      第一次编译的时候:

      使用64位的系统第一次编译安装出现

      error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory这种情况,nginx默认是在lib64下,32为的是在lib下

      查找:find / -name 'libpcre.so.1'  出现 /usr/local/lib/libpcre.so.1,我们建立以符号链接:ln -s /usr/local/lib/libpcre.so.1 /lib64/libpcre.so.1

      这样可以查看nginx版本 /usr/local/nginx/sbin/nginx -v  出现版本号

    4、nginx配置

      cd /usr/local/nginx/conf ,把下面的内容覆盖到nginx.conf,内容从菜鸟网站上搜索的

    [root@bogon conf]#  cat /usr/local/webserver/nginx/conf/nginx.conf
    
    user www www;
    worker_processes 2; #设置值和CPU核心数一致
    error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
    pid /usr/local/webserver/nginx/nginx.pid;
    #Specifies the value for maximum file descriptors that can be opened by this process.
    worker_rlimit_nofile 65535;
    events
    {
      use epoll;
      worker_connections 65535;
    }
    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';
      
    #charset gb2312;
         
      server_names_hash_bucket_size 128;
      client_header_buffer_size 32k;
      large_client_header_buffers 4 32k;
      client_max_body_size 8m;
         
      sendfile on;
      tcp_nopush on;
      keepalive_timeout 60;
      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 128k;
      gzip on; 
      gzip_min_length 1k;
      gzip_buffers 4 16k;
      gzip_http_version 1.0;
      gzip_comp_level 2;
      gzip_types text/plain application/x-javascript text/css application/xml;
      gzip_vary on;
     
      #limit_zone crawler $binary_remote_addr 10m;
     #下面是server虚拟主机的配置
     server
      {
        listen 80;#监听端口
        server_name localhost;#域名
        index index.html index.htm index.php;
        root /usr/local/webserver/nginx/html;#站点目录
          location ~ .*.(php|php5)?$
        {
          #fastcgi_pass unix:/tmp/php-cgi.sock;
          fastcgi_pass 127.0.0.1:9000;
          fastcgi_index index.php;
          include fastcgi.conf;
        }
        location ~ .*.(gif|jpg|jpeg|png|bmp|swf|ico)$
        {
          expires 30d;
      # access_log off;
        }
        location ~ .*.(js|css)?$
        {
          expires 15d;
       # access_log off;
        }
        access_log off;
      }
    
    }

    可以检测配置的是否正确

    [root@iZbp1bb2egi7w0ueys548pZ /]# /usr/local/nginx/sbin/nginx -t

    出现test is successful字样说明OK

    [root@iZbp1bb2egi7w0ueys548pZ sbin]# /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

    5、启动nginx

    [root@iZbp1bb2egi7w0ueys548pZ /]# /usr/local/nginx/sbin/nginx

    注意不要到sbin目录下执行nginx,否则会报错:-bash: nginx: command not found

    [root@iZbp1bb2egi7w0ueys548pZ sbin]# nginx
    -bash: nginx: command not found

      启动的时候有报错,如下

      nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
      nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
      nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
      nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)...

      这说明80接口有被占用,查看端口

      netstat -ntpl

      

      或者

      ps -ef |grep nginx

      查看master的进程号

      

      kill -QUIT pid

      再次启动

      /usr/local/nginx/sbin/nginx

      网页访问  127.0.0.1

      

      至此,安装配置完成!

      在学习过程中配到问题:

      1、在下载安装pcre和nginx中,要用root身份,一般下载到/usr/local/src/,下载到其他地方配置呢?(测试几次没成功)

      2、菜鸟网站中编译nginx的时候 配置安装地址 

       ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35

       编译不成功?(配置安装路径应该没问题,编译的时候报pcrelib.so.0不存在,安装的时候webserver文件没有建立成功,想着应该还是和64位的配置文件路径有关系,有待验证)  

    6、卸载nginx

      删除nginx文件即可

      rm -rf /usr/local/nginx
