Centos下安装nginx步骤解析

  最近研究LNMP,首先要在linux下配置nginx服务器,话不多说,上步骤
  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++ libtoolopenssl openssl-devel
  2、首先安装PCREpcre功能是让nginx有rewrite功能
  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
  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
  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默认地址 /usr/local/nginx
  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
  

user www www;  
worker_processes
2; #设置值和CPU核心数一致  
error_log
/usr/local/nginx/logs/nginx_error.log crit; #日志位置和日志级别  
pid
/usr/local/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 $binary_remote_addr 10m;
  #下面是server虚拟主机的配置
  server
  {
  listen 80;#监听端口
  server_name localhost;#域名
  index index.html index.htm index.php;
  root /usr/local/nginx/html;#站点目录
  location ~ .*\.(php|php5)?$
  {
  #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
  /usr/local/nginx/sbin/nginx -t

  说明配置成功
  5、启动nginx
  启动的时候有报错,如下
  nginx: bind() to 0.0.0.0:80 failed (98: Address already in use)
  nginx: bind() to 0.0.0.0:80 failed (98: Address already in use)
  nginx: bind() to 0.0.0.0:80 failed (98: Address already in use)
  nginx: bind() to 0.0.0.0:80 failed (98: Address already in use)...
  这说明80接口有被占用,查看接口
  netstat -ntpl
  kill -9 $pid //杀掉进程
  再次启动
  /usr/local/nginx/sbin/nginx
  停止服务器
  /usr/local/nginx/sbin/nginx -s stop 或 /usr/local/nginx/sbin/nginx -s quick
  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
