linux下nginx负载实现

1.创建下载路径

mkdir  /usr/local/nginx

2.进入nginx路径下

 cd  /usr/local/nginx

3.通过wget命令下载nginx压缩包

wget -c https://nginx.org/download/nginx-1.10.1.tar.gz

4.安装gcc-c++

yum install gcc-c++

5.安装pcre pcre-devel

yum install -y pcre pcre-devel

6.安装zlib

yum install -y zlib zlib-devel

7.安装open ssl

yum install -y openssl openssl-devel

8.进入/usr/local/nginx路径下，在解压 nginx-1.10.1.tar.gz

cd /usr/local/nginx

tar -zxvf nginx-1.10.1.tar.gz

9.进入解压文件

cd nginx-1.10.1

10默认配置

./configure

11.编译安装首先进入目录（/usr/local/nginx-1.10.1）

cd /usr/local/nginx-1.10.1

make

make install

12.进入/usr/local/nginx/sbin目录

cd /usr/local/nginx/sbin

13.启动nginx（在/usr/local/nginx/sbin目录 ）

./nginx

14.关闭nginx

./nginx -s quit

 或者

./nginx -s stop

15.重启nginx

./nginx -s reload

16.查看进程

ps aux|grep nginx

负载均衡测试

cd /usr/local/nginx

cp -r html /html2/

cd html2/

vim index.html

cd /usr/local/nginx/conf

修改配置文件
