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: http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
[root@bogon src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
2、解压安装包:
[root@bogon src]# tar zxvf pcre-8.35.tar.gz
3、进入安装包目录
[root@bogon src]# cd pcre-8.35
4、编译安装
[root@bogon pcre-8.35]# ./configure
[root@bogon pcre-8.35]# make && make install
5、查看pcre版本
[root@bogon pcre-8.35]# pcre-config --version
三、安装 Nginx
1、下载安装包
[root@bogon src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz
2、解压安装包
[root@bogon src]# tar zxvf nginx-1.6.2.tar.gz
3、进入安装包目录
[root@bogon src]# cd nginx-1.6.2
4、编译安装
[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
5、查看nginx版本。到此,nginx安装完成。
[root@bogon nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v
6、检查配置文件nginx.conf的正确性命令:
[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t
7、启动 Nginx
[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx
8、访问站点
从浏览器访问我们配置的站点ip:
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
四:负载均衡
1、建立三台主机 有三个tomcat 建立一个简单的项目test
2、/nginx/conf文件修改参数
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
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;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;

}

#

location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80

}
