centos7.4 下安装 uginx

参考给小白的 Nginx 30分钟入门指南

one、安装：

root 用户登录
1、yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel
2、[root@bogon ~]#  wget  https://jaist.dl.sourceforge.net/project/pcre/pcre/8.42/pcre-8.42.tar.gz
3、[root@bogon ~]#  tar zxvf pcre-8.42.tar.gz    # 解压 
4、[root@bogon ~]#   cd pcre-8.42
5、[root@bogon pcre-8.42]#  ./configure
6、[root@bogon pcre-8.42]#   make && make install
7、[root@bogon pcre-8.42]#   pcre-config --version
8、[root@bogon ~]#  wget  https://nginx.org/download/nginx-1.15.1.tar.gz
9、[root@bogon ~]# tar zxvf nginx-1.15.1.tar.gz
10、[root@bogon ~]# cd nginx-1.15.1
11、[root@bogon nginx-1.15.1]# ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/root/pcre-8.42    # 注意此 /root/pcre-8.42 为 pcre-8.42.tar.gz 解压后的文件夹
12、[root@bogon nginx-1.15.1]# make
13、[root@bogon nginx-1.15.1]# make install
14、[root@bogon nginx-1.15.1]# /usr/local/webserver/nginx/sbin/nginx -v

two、创建 Nginx 运行使用的用户 userweb：

useradd userweb
passwd userweb

Three、配置 /usr/local/webserver/nginx/conf/nginx.conf：

user userweb userweb;
worker_processes 4; #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';
  access_log  logs/access.log  main;
#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
    error_page   500 502 503 504  /50x.html;
      location = /50x.html 
    {
      root   /usr/local/webserver/nginx/html;
    }

      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;
  }
}

four、 检查 nginx 配置文件正确性

/usr/local/webserver/nginx/sbin/nginx -t

five、启动 nginx

/usr/local/webserver/nginx/sbin/nginx

six、访问服务器 IP

seven、配置 nginx 自启动，参考(https://www.cnblogs.com/phpandmysql/p/7966538.html)<3、添加到系统服务>部分

vim /etc/init.d/nginx

#!/bin/sh 
# chkconfig: 2345 85 15 
# Startup script for the nginx Web Server 
# description: nginx is a World Wide Web server.  
# It is used to serve HTML files and CGI. 
# processname: nginx 
   
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin 
DESC="nginx deamon" 
NAME=nginx 
DAEMON=/usr/local/webserver/nginx/sbin/$NAME
SCRIPTNAME=/etc/init.d/$NAME 
   
test -x $DAEMON || exit 0 
   
d_start(){ 
  $DAEMON || echo -n "already running" 
} 
   
d_stop(){ 
  $DAEMON -s quit || echo -n "not running" 
} 
   
   
d_reload(){ 
  $DAEMON -s reload || echo -n "can not reload" 
} 
   
case "$1" in 
start) 
  echo -n "Starting $DESC: $NAME" 
  d_start 
  echo "." 
;; 
stop) 
  echo -n "Stopping $DESC: $NAME" 
  d_stop 
  echo "." 
;; 
reload) 
  echo -n "Reloading $DESC conf..." 
  d_reload 
  echo "reload ." 
;; 
restart) 
  echo -n "Restarting $DESC: $NAME" 
  d_stop 
  sleep 2 
  d_start 
  echo "." 
;; 
*) 
  echo "Usage: $ScRIPTNAME {start|stop|reload|restart}" >&2 
  exit 3 
;; 
esac 
exit 0  

eight、保存退出后，再使用下面的命令，使其可执行；然后，添加配置并查看。可用chkconfig修改其值，也可用ntsysv工具改变是否自启动。

chmod +x /etc/init.d/nginx 
chkconfig --add nginx 
chkconfig nginx on/off     #  添加自启动 / 删除自启动
chkconfig --list nginx    
root 用户权限：
service nginx start
service nginx stop
#  nginx 0:off 1:off 2:on 3:on 4:on 5:on 6:off
