Config shadowsocks-libev on Linux

With no time updating Twist, I wrote this extremly simple script to setup shadowsocks-libev both server and client.

apt-get update -y
apt-get upgrade -y
apt-get dist-upgrade -y
apt-get autoremove -y
apt-get install --no-install-recommends -y gettext build-essential autoconf libtool libpcre3-dev asciidoc xmlto libev-dev libc-ares-dev automake golang golang-go fail2ban apache2 unzip git
git clone https://github.com/jedisct1/libsodium --branch master
pushd libsodium
bash autogen.sh
./configure --prefix=/usr
make
make install
ldconfig
popd
mbedtlsver="$(wget -qO- https://tls.mbed.org/download-archive | grep -oE '[0-9]+\.[0-9]+\.[0-9]+' | cut -d'.' -f1,2,3 | sort -V | tail -1)"
wget -t 3 -T 30 -nv -O mbedtls-${mbedtlsver}-gpl.tgz https://tls.mbed.org/download/mbedtls-${mbedtlsver}-gpl.tgz
tar xf mbedtls-${mbedtlsver}-gpl.tgz
pushd mbedtls-${mbedtlsver}
make SHARED=1 CFLAGS=-fPIC
make DESTDIR=/usr install
ldconfig
popd
git clone https://github.com/shadowsocks/shadowsocks-libev.git
pushd shadowsocks-libev
git submodule update --init --recursive
bash autogen.sh
./configure --disable-documentation
make
make install
ldconfig
popd
git clone https://github.com/shadowsocks/simple-obfs.git
pushd simple-obfs
git submodule update --init --recursive
./autogen.sh
./configure
make
make install
ldconfig
popd
git clone https://github.com/shadowsocks/v2ray-plugin.git
pushd v2ray-plugin
go get
go build
ldconfig
popd
rm -fr libsodium mbedtls-${mbedtlsver}-gpl.tgz mbedtls-${mbedtlsver} shadowsocks-libev simple-obfs v2ray-plugin
sleep 3
reboot

Server-side configuration should be like this before replaced by customized configuration. It stored in /etc/shadowsocks-libev/config.json by default, you can use sudo nano /etc/shadowsocks-libev/config.json to edit it.

{
    "server":["0.0.0.0","[::0]"],
    "server_port":serverport,
    "password":"serverpassword",
    "method":"encryptmethod",
    "timeout":7200,
    "udp_timeout":7200,
    "fast_open":true,
    "reuse_port":true,
    "plugin":"obfs-server",
    "plugin_opts":"obfs=tls;fast-open;failover=obfshost:serverport",
    "nofile":512000,
    "nameserver":"nameserver1,nameserver2",
    "dscp":"EF",
    "mode":"tcp_and_udp",
    "mptcp":false,
    "ipv6_first":false,
    "no_delay":true,
}

This would be client configuration example which is always stored in /etc/shadowsocks-libev/config.json and you can also use sudo nano /etc/shadowsocks-libev/config.json to edit it. It necessary to replace all the infomation which matches to your server-side configuration.

{
    "local_port":"localport",
    "server":"serverhost",
    "fast_open":true,
    "reuse_port":true,
    "nameserver":"nameserver1,nameserver2",
    "mode":"tcp_and_udp",
    "no_delay":true,
    "server_port":serverport,
    "password":"serverpassword",
    "method":"encryptmethod",
    "plugin":"obfs-local",
    "plugin_opts":"obfs=tls;fast-open;obfs-host=obfshost",
    "timeout":5
}

To start server, it's better to use systemctl enable shadowsocks-libev and systemctl start shadowsocks-libev, and it will set shadowsocks-libev to start while starting system.

Staring shadowsocks-libev client is a little different from starting server. Firstly the file /etc/systemd/system/shadowsocks-libev.service should be change by editing it using nano /etc/systemd/system/shadowsocks-libev.service. Then relpace the line matches ExecStart= with ExecStart=/usr/bin/ss-local -c $CONFFILE $DAEMON_ARGS. Last use the same command as starting server to start shadowsocks-libev client.

You can also monitor the status of your server both client by systemctl status shadowsocks-libev and for shadowsocks-libev client it shows like this as ss-local:
