LNMP架构(2)Nginx安装,默认虚拟主机,Nginx用户认证,Nginx域名重定向

Nginx安装1、下载并解压安装包[[email protected] ~]# cd /usr/local/src/[[email protected] src]# wget http://nginx.org/download/nginx-1.12.2.tar.gz[[email protected] src]# tar zxvf nginx-1.12.2.tar.gz2、配置编译选项[[email protected] src]# cd nginx-1.12.2[[email protected] nginx-1.12.2]# ./configure --prefix=/usr/local/nginx3、编译和安装[[email protected] nginx-1.12.2]# make[[email protected] nginx-1.12.2]# make install4、编写Nginx启动脚本并加入系统服务和开机启动[[email protected] nginx-1.12.2]# vim /etc/init.d/nginx

#!/bin/bash# chkconfig: - 30 21# description: http service.# Source Function Library . /etc/init.d/functions# Nginx Settings NGINX_SBIN="/usr/local/nginx/sbin/nginx" NGINX_CONF="/usr/local/nginx/conf/nginx.conf" NGINX_PID="/usr/local/nginx/logs/nginx.pid" RETVAL=0 prog="Nginx"start() { echo -n $"Starting $prog: " mkdir -p /dev/shm/nginx_temp daemon $NGINX_SBIN -c $NGINX_CONF RETVAL=$? echo return $RETVAL }stop() { echo -n $"Stopping $prog: " killproc -p $NGINX_PID $NGINX_SBIN -TERM rm -rf /dev/shm/nginx_temp RETVAL=$? echo return $RETVAL }reload() { echo -n $"Reloading $prog: " killproc -p $NGINX_PID $NGINX_SBIN -HUP RETVAL=$? echo return $RETVAL }restart() { stop start }configtest() { $NGINX_SBIN -c $NGINX_CONF -t return 0 }case "$1" in start) start ;; stop) stop ;; reload) reload ;; restart) restart ;; configtest) configtest ;; *) echo $"Usage: $0 {start|stop|reload|restart|configtest}" RETVAL=1esacexit $RETVAL

[[email protected] nginx-1.12.2]# chmod 755 /etc/init.d/nginx
[[email protected] nginx-1.12.2]#chkconfig --add nginx
[[email protected] nginx-1.12.2]# chkconfig nginx on

5、更改Nginx配置文件[[email protected] nginx-1.12.2]# > /usr/local/nginx/conf/nginx.conf[[email protected] nginx-1.12.2]#vim /usr/local/nginx/conf/nginx.conf

user nobody nobody;

    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;

    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;
        server_name localhost;
        index index.html index.htm index.php;
        root /usr/local/nginx/html;
        location ~ \.php$
        {
            include fastcgi_params;
            fastcgi_pass unix:/tmp/php-fcgi.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
        }    
    }
}
[[email protected] nginx-1.12.2]# service nginx start
[[email protected] nginx-1.12.2]# ps aux |grep nginx
root      14119  0.0  0.0  20500   628 ?        Ss   14:54   0:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nobody    14120  0.0  0.1  22944  3212 ?        S    14:54   0:00 nginx: worker process
nobody    14121  0.0  0.1  22944  3212 ?        S    14:54   0:00 nginx: worker process
root      14123  0.0  0.0 112680   968 pts/0    R+   14:54   0:00 grep --color=auto nginx
6、测试是否正确解析PHP[[email protected] nginx-1.12.2]# vim /usr/local/nginx/html/test.php //写入以下内容<?phpecho "This is a test php page!";?>[[email protected] nginx-1.12.2]# curl localhost/test.phpThis is a test php page! //出现这个说明解析正常
默认虚拟主机 在Nginx中也有默认虚拟主机,跟httpd类似,第一个被Nginx加载的虚拟主机就是默认主机,但和httpd不相同的地方是,它还有一个配置用来标记默认虚拟主机,也就是说,如果没有这个标记,第一个虚拟主机为默认虚拟主机。1、修改主配置文件[[email protected] nginx-1.12.2]#vim /usr/local/nginx/conf/nginx.conf //修改为以下内容#加入这行,意思是/usr/local/nginx/conf/vhost/下面所有以.conf结尾的都会加载
 include vhost/*.conf;#这里方便实验先注释掉server的内容#    server#    {#        listen 80;#        server_name localhost;#        index index.html index.htm index.php;#        root /usr/local/nginx/html;#        location ~ \.php$ #        {#            include fastcgi_params;#            fastcgi_pass unix:/tmp/php-fcgi.sock;#            fastcgi_index index.php;#            fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;#        }    #    }   
}  
2、创建vhost目录及配置文件[[email protected] ~]# mkdir /usr/local/nginx/conf/vhost
[[email protected] ~]# cd /usr/local/nginx/conf/vhost[[email protected] vhost]# vim zlinux.conf //写入以下内容

server
{
   listen 80 default_server;   //有这个标记的就是默认虚拟主机
   server_name zlinux.com;
   index index.html index.htm index.php;
   root /data/wwwroot/default;
}
[[email protected] vhost]# mkdir /data/wwwroot
[[email protected] vhost]# mkdir /data/wwwroot/default[[email protected] vhost]# /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
[[email protected] vhost]# /usr/local/nginx/sbin/nginx -s reload //重新加载配置文件[[email protected] vhost]# echo "这是默认主机" > /data/wwwroot/default/index.html
[[email protected] vhost]# curl -x127.0.0.1:80 zlinux.com
这是默认主机[[email protected] vhost]# curl -x127.0.0.1:80 11223.com //访问一个没有定义的网址,一会访问到zlinux.com
这是默认主机
