十二周二课 Nginx安装、Nginx默认虚拟主机、Nginx用户认证、Nginx域名重定向
Nginx安装首先进入/usr/local/src目录。然后下载Nginx。
wget http://nginx.org/download/nginx-1.12.1.tar.gz
然后解压
tar zxf nginx-1.12.1.tar.gz
然后进入我们刚才解压好的目录进行编译
cd nginx-1.12.1
# ./configure --prefix=/usr/local/nginx
这里没有加编译参数，我们可以根据实际情况，在后期编译的时候去添加参数。
在以后我们安装环境的时候，源码包一定要保留，因为我们不一定需要什么模块，所以保留源码包还是很必要的。
编译完成后我们进行安装
make &&make install
安装完后我们会得到四个目录
# ls /usr/local/nginx/
confhtmllogssbin
然后我们编辑一个启动脚本
vim /etc/init.d/nginx
#!/bin/bash
chkconfig: - 30 21
description: http service.

. /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

echo $"Usage: $0 {start|stop|reload|restart|configtest}"

esac
exit $RETVAL

然后更改权限启动脚本的权限
chmod 755 /etc/init.d/nginx
chkconfig --add nginx
开机自启动
chkconfig nginx on
然后我们更改一下nginx的配置文件，我们要将原来的配置文件清空。
首先我们进入nginx的配置文件目录
cd /usr/local/nginx/conf/
然后将以前的配置文件清空
/usr/local/nginx/conf/nginx.conf（>重定向符号，单独使用，可以吧一个文档快速清空。）
然后编辑配置文件
vim /usr/local/nginx/conf/nginx.conf
user nobody nobody;
worker_processes 2;
error_log /usr/local/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/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" "$http_user_agent"';
sendfile on;
tcp_nopush on;
keepalive_timeout 30;
client_header_timeout 3m;
client_body_timeout 3m;
send_timeout 3m;
connection_pool_size 256;
client_header_buffer_size 1k;
large_client_header_buffers 8 4k;
request_pool_size 4k;
output_buffers 4 32k;
postpone_output 1460;
client_max_body_size 10m;
client_body_buffer_size 256k;
client_body_temp_path /usr/local/nginx/client_body_temp;
proxy_temp_path /usr/local/nginx/proxy_temp;
fastcgi_temp_path /usr/local/nginx/fastcgi_temp;
fastcgi_intercept_errors on;
tcp_nodelay on;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 8k;
gzip_comp_level 5;
gzip_http_version 1.1;
gzip_types text/plain application/x-javascript text/css text/htm
application/xml;
server
{
listen 80;
server_name localhost;
index index.html index.htm index.php;
root /usr/local/nginx/html;
location ~ .php$
{
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;
}
}
}
也可以去网站直接复制https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/nginx.conf
然后检查是否有语法错误
#/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
配置语法正确。
然后我们启动nginx
/etc/init.d/nginxstart
启动后查看是否成功启动
# ps aux |grep nginx
root 52130.00.020496 620 ? Ss 22:10 0:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nobody 52140.00.3229403208 ? S 22:10 0:00 nginx: worker process
nobody 52150.00.3229403208 ? S 22:10 0:00 nginx: worker process
root 52190.00.0 112676 976 pts/0 R+ 22:10 0:00 grep --color=auto nginx
上面显示有两个worker，说明启动成功。然后我们查看一下端口
#netstat -lntp |grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 5213/nginx: master
已经成功的监听了80端口。
然后我们看是否能解析php
首先编辑文件
vim /usr/local/nginx/html/1.php
然后输入内容
