安装

到nginx官网下载对应版本的nginx，地址http://nginx.org/en/download.html
我这里下载的是nginx-1.8.1.tar.gz
上传至服务器

1
scp nginx-1.8.1.tar.gz root@192.168.0.112:/home

登录服务器并进入home目录
首先先安装必要的安装的环境，执行如下命令

1

3
yum install gcc gcc-c++ -y
yum install pcre.x86_64 pcre-devel.x86_64 -y
yum install zlib-devel.x86_64 zlib.x86_64 -y

解压

1
tar -zxvf nginx-1.8.1.tar.gz -C /usr/local/

设置配置

1
2
cd /usr/local/nginx-1.8.1
./configure --prefix=/usr/local/nginx --with-pcre --user=daemon --group=daemon --with-http_stub_status_module

编译与安装

1
make && make install

此时nginx将会安装到/usr/local/nginx中
建立软连接，以便在任何目录下都能执行nginx命令

1
ln -s /usr/local/nginx/sbin/nginx   /usr/local/sbin/

配置

编辑配置

1
vim nginx.conf

192.168.0.110:8080和192.168.0.111:8080是两个运行在tomcat上的web服务
