Nginx(“engine x“)是一款是由俄罗斯的程序设计师Igor Sysoev所开发高性能的 Web和 反向代理 服务器,也是一个 IMAP/POP3/SMTP 代理服务器。在高连接并发的情况下,Nginx是Apache服务器不错的替代品。
Nginx 安装
系统平台:CentOS release 6.6 (Final) 64位。
一、安装编译工具及库文件
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
二、首先要安装 PCRE
PCRE 作用是让 Nginx 支持 Rewrite 功能。
1、下载 PCRE 安装包,下载地址: downloads.sourceforge.net/project/pcr…
[root@bogon src]# cd /usr/local/src/
[root@bogon src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
[root@bogon src]# tar zxvf pcre-8.35.tar.gz
[root@bogon src]# cd pcre-8.35
[root@bogon pcre-8.35]# ./configure
[root@bogon pcre-8.35]# make && make install
[root@bogon pcre-8.35]# pcre-config --version
安装 Nginx
1、下载 Nginx,下载地址:nginx.org/en/download…
[root@bogon src]# cd /usr/local/src/
[root@bogon src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz
[root@bogon src]# tar zxvf nginx-1.6.2.tar.gz
[root@bogon src]# cd nginx-1.6.2
[root@bogon nginx-1.6.2]# ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
[root@bogon nginx-1.6.2]# make
[root@bogon nginx-1.6.2]# make install
[root@bogon nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v
到此,nginx安装完成。
Nginx 配置
[root@bogon conf]# /usr/sbin/groupadd www
[root@bogon conf]# /usr/sbin/useradd -g www www
配置nginx.conf,将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容。
[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.

# access_log off;
}
access_log off;
}
}
[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t
启动 Nginx
Nginx 启动命令如下:
[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx
访问站点
Nginx 其他命令
以下包含了 Nginx 常用的几个命令:
/usr/local/webserver/nginx/sbin/nginx -s reload # 重新载入配置文件
/usr/local/webserver/nginx/sbin/nginx -s reopen # 重启 Nginx
/usr/local/webserver/nginx/sbin/nginx -s stop # 停止 Nginx
关于 uri 的截取
- root 指令只是将搜索的根设置为 root 设定的目录,即不会截断 uri,而是使用原始 uri 跳转该目录下查找文件
- aias 指令则会截断匹配的 uri,然后使用 alias 设定的路径加上剩余的 uri 作为子路径进行查找
示例 1:root
#------------目录结构----------
/www/x1/index.html
/www/x2/index.html
#--------配置-----------------------
index index.html index.php;
location /x/ {
root "/www/";
}
#-------访问--------------
curl http://localhost/x1/index.html
curl http://localhost/x2/index.html
#----------配置-----------------
location /y/z/ {
alias /www/x1/;
}
#---------访问--------------
curl http://localhost/y/z/index.html
如果proxy_pass的url带uri,则会截断匹配的uri
示例:
#-------servers配置--------------------
location / {
echo $uri #回显请求的uri
}
#--------proxy_pass配置---------------------
location /t1/ { proxy_pass http://servers; } #正常,不截断
location /t2/ { proxy_pass http://servers/; } #正常,截断
location /t3 { proxy_pass http://servers; } #正常,不截断
location /t4 { proxy_pass http://servers/; } #正常,截断
location /t5/ { proxy_pass http://servers/test/; } #正常,截断
location /t6/ { proxy_pass http://servers/test; } #缺"/",截断
location /t7 { proxy_pass http://servers/test/; } #含"//",截断
location /t8 { proxy_pass http://servers/test; } #正常,截断
#---------访问----------------------
for i in $(seq 6)
do
url=http://localhost/t$i/doc/index.html
echo "-----------$url-----------"
curl url
done
#--------结果---------------------------
----------http://localhost:8080/t1/doc/index.html------------
/t1/doc/index.html
----------http://localhost:8080/t2/doc/index.html------------
/doc/index.html
----------http://localhost:8080/t3/doc/index.html------------
/t3/doc/index.html
----------http://localhost:8080/t4/doc/index.html------------
/doc/index.html
----------http://localhost:8080/t5/doc/index.html------------

----------http://localhost:8080/t6/doc/index.html------------

----------http://localhost:8080/t7/doc/index.html------------

----------http://localhost:8080/t8/doc/index.html------------
