安装基于java的ss服务端程序：shadowsocks-netty-server (速度较慢，不建议使用）

首先搭建java环境:
apt-get install -y default-jre (或者安装openjdk-7-jre)   

这样java环境就搭建好了。

接着是搭建maven环境,参考http://briteming.blogspot.com/2013/10/linux-vpsjava-opoopress.html 

root@umh:~# mvn -version

Apache Maven 3.0.5
(0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 11:22:22-0400)

Java version: 1.7.0_151, vendor: Oracle Corporation

Java home: /usr/lib/jvm/java-7-openjdk-amd64/jre

Default locale: zh_CN, platform encoding: UTF-8

OS name: "linux", version: "2.6.32-042stab103.6", arch: "amd64", family: "unix"

root@umh:~#

(运行 mvn -version 命令,检验是否正确地安装了 Maven。如上的显示则表明正确地安装了 Maven。）

然后，

git clone https://github.com/ksfzhaohui/shadowsocks-netty-server

cd shadowsocks-netty-server

root@umh:~/shadowsocks-netty-server# ls

README.md  conf  pom.xml  shell  src  

root@umh:~/shadowsocks-netty-server# mvn package

(会在当前目录下，生成target目录）

root@umh:~/shadowsocks-netty-server# ls

README.md  conf  pom.xml  shell  src  target

root@umh:~/shadowsocks-netty-server# cd target

root@umh:~/shadowsocks-netty-server/target# ls

archive-tmp  classes  shadowsocks-netty-server-0.0.1-bin.zip shadowsocks-netty-server-0.0.1.jar

root@umh:~/shadowsocks-netty-server/target# rm -rf  shadowsocks-netty-server-0.0.1.jar
(当前目录下的这个shadowsocks-netty-server-0.0.1.jar有问题，故删除它）

root@umh:~/shadowsocks-netty-server/target# unzip shadowsocks-netty-server-0.0.1-bin.zip

root@umh:~/shadowsocks-netty-server/target# 

root@umh:~/shadowsocks-netty-server/target# ls 

archive-tmp  classes  shadowsocks-netty-server-0.0.1  shadowsocks-netty-server-0.0.1-bin.zip

root@umh:~/shadowsocks-netty-server/target# cd shadowsocks-netty-server-0.0.1

root@umh:~/shadowsocks-netty-server/target/shadowsocks-netty-server-0.0.1# ls

conf  lib  logs  shadowsocks-netty-server-0.0.1.jar  shadowsocks-netty-server.bat  shadowsocks-netty-server.sh

root@umh:~/shadowsocks-netty-server/target/shadowsocks-netty-server-0.0.1# nano conf/config.xml

root@umh:~/shadowsocks-netty-server/target/shadowsocks-netty-server-0.0.1# cat conf/config.xml

<?xml version="1.0" encoding="UTF-8" ?>

<config>

<local_port>10820</local_port>

<method>aes-256-cfb</method>

<password>your-password</password>

</config>

root@umh:~/shadowsocks-netty-server/target/shadowsocks-netty-server-0.0.1# java -jar shadowsocks-netty-server-0.0.1.jar

不过命令：java -jar shadowsocks-netty-server-0.0.1.jar是运行在前台的，容易退出。我们可以利用systemd来把该命令运行为service:

nano /etc/systemd/system/shadowsocks-netty-server.service

内容为：

[Unit]

After=network.target

[Service]

WorkingDirectory=/root/shadowsocks-netty-server/target/shadowsocks-netty-server-0.0.1/

ExecStart=/usr/bin/java -jar /root/shadowsocks-netty-server/target/shadowsocks-netty-server-0.0.1/shadowsocks-netty-server-0.0.1.jar

Restart=always

[Install]

WantedBy=multi-user.target

然后运行：

systemctl start shadowsocks-netty-server

systemctl enable shadowsocks-netty-server

服务器端搭建完成。

至于客户端，通用通常的ss客户端程序。也可使用此文https://briteming.blogspot.com/2018/10/javassshadowsocks-netty.html里所说的客户端程序。
