Nginx配置tcp请求端口转发 stream { # 添加socket转发的代理 upstream socket_proxy { hash $remote_addr consistent; # 转发的目的地址和端口 server 192.168.1.100:9000 weight=5 max_fails=3 fail_timeout=30s; } # 提供转发的服务，即访问localhost:9001，会跳转至代理socket_proxy指定的转发地址 server { listen 9001; proxy_connect_timeout 1s; proxy_timeout 3s; proxy_pass socket_proxy; } }

CentOS配置jdk环境变量 1.下载linux版1.8JDK包安装版本 jdk-8u191-linux-x64.tar.gz 为例2.解压安装包到指定目录tar -zxvf jdk-8u191-linux-x64.tar.gz3.配置环境变量并生效（1）root用户打开配置文件 /etc/profilevi /etc/profile在末尾添加以下内容：export JAVA_HOME=/home/$USER/programs/soft/jdk1.8.0_381 export CLASSPATH=.:${JAVA_HOME}/jre/lib/rt.jar:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar export PATH=$PATH:${JAVA_HOME}/bin（2）普通用户vi ~/.bash_profile在.bash_profile文件中填入如下语句：export PATH export JAVA_HOME=/home/$USER/programs/soft/jdk1.8.0_381 export PATH=$JAVA_HOME/bin:$PATH export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar4.使配置文件生效source /etc/profilesource ~/.bash_profile5.检验java环境java -version出现以下内容：java version "1.8.0_381" Java(TM) SE Runtime Environment (build 1.8.0_381-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)
