  1. 项目的Github地址
  2. 官方部署教程,适用于Centos6

准备工作

  1. 更新yum源
    yum update
  2. 添加epel源
    yum install -y epel-release
  3. 安装git等

    1
    2
    3
    yum install -y git
    yum install -y wget
    yum install python-setuptools && easy_install pip
  4. 安装 libsodium

    6
    yum -y groupinstall "Development Tools"
    wget https://github.com/jedisct1/libsodium/releases/download/1.0.13/libsodium-1.0.13.tar.gz
    tar xf libsodium-1.0.13.tar.gz && cd libsodium-1.0.13
    ./configure && make -j2 && make install
    echo /usr/local/lib > /etc/ld.so.conf.d/usr_local_lib.conf
    ldconfig

git clone -b manyuser https://github.com/glzjin/shadowsocks.git
cd shadowsocks
yum -y install python-devel
yum -y install libffi-devel
yum -y install openssl-devel
pip install -r requirements.txt

获取配置文件

cd /root/shadowsocks
cp apiconfig.py userapiconfig.py
cp config.json user-config.json

主要编辑 userapiconfig.py ,来解释下里面各项配置的意思

运行的话,有几种方式。

  • python server.py 用于调错的
  • ./run.sh 无日志后台运行
  • ./logrun.sh 有日志后台运行
  • supervisord

编辑 /etc/security/limits.conf
最后添加
* soft nofile 51200
* hard nofile 51200
然后在运行之前执行
ulimit -n 51200
然后编辑 /etc/sysctl.conf
fs.file-max = 51200
net.core.rmem_max = 67108864
net.core.wmem_max = 67108864

保存
sysctl -p 来使其生效。

yum install supervisor python-pip -y

wget https://github.com/glzjin/ssshell-jar/raw/master/supervisord.conf -O /etc/supervisord.conf
wget https://raw.githubusercontent.com/Supervisor/initscripts/master/centos-systemd-etcs -O /usr/lib/systemd/system/systemd-supervisor.service
vi /usr/lib/systemd/system/systemd-supervisor.service
在里面加入LimitNOFILE=512000

编辑 /etc/supervisord.conf 最后一段改成如下的,以 /root/shadowsocks/ 为例
[program:mu]
command=python /root/shadowsocks/server.py
directory=/root/shadowsocks
autorestart=true
startsecs=10
startretries=36
redirect_stderr=true
user=root ; setuid to this UNIX account to run the program
log_stdout=true ; if true, log program stdout (default true)
log_stderr=true ; if true, log program stderr (def false)
logfile=/var/log/mu.log ; child log path, use NONE for none; default AUTO
;logfile_maxbytes=1MB ; max # logfile bytes b4 rotation (default 50MB)
;logfile_backups=10 ; # of logfile backups (default 10)
保存

然后

`systemctl enable systemd-supervisor`设置开机自启
`systemctl start systemd-supervisor`启动supervisord
`systemctl status systemd-supervisor`查看supervisord运行情况

如果运行正常,节点不能使用可能需要在iptables里放行端口

vi /etc/sysconfig/iptables
-A INPUT -p tcp -m tcp --dport 1025: -j ACCEPT 添加这一行
保存
-A INPUT -p tcp -m state --dport 443 --state NEW -j ACCEPT
-A INPUT -p udp -m state --dport 443 --state NEW -j ACCEPT
-A INPUT -p udp -m udp --dport 443 -j ACCEPT
单端口同时开启tcp和udp
systemctl restart iptables.service 重启iptables
