我修改之后的脚本如下，原文中的 LIBSODIUM_VER 版本 1.0.13 文件 404 了，所以换了 1.0.17 版本。去这个网页查看当前存在哪些文件: https://download.libsodium.org/libsodium/releases/

创建 /home/你的用户名/temp/install-shadowsocks-libev.sh，并赋予可执行权限 $ sudo chmod +x /home/你的用户名/temp/install-shadowsocks-libev.sh

#!/bin/bash
# install dependencies
yum update -y
yum install -y pcre pcre-devel git gettext gcc autoconf libtool automake make asciidoc xmlto c-ares-devel libev-devel

export LIBSODIUM_VER=1.0.17
wget https://download.libsodium.org/libsodium/releases/libsodium-$LIBSODIUM_VER.tar.gz
tar xvf libsodium-$LIBSODIUM_VER.tar.gz
pushd libsodium-$LIBSODIUM_VER
./configure --prefix=/usr && make
#./configure && make && make check
make install
popd
ldconfig

export MBEDTLS_VER=2.6.0
wget https://tls.mbed.org/download/mbedtls-$MBEDTLS_VER-gpl.tgz
tar xvf mbedtls-$MBEDTLS_VER-gpl.tgz
pushd mbedtls-$MBEDTLS_VER
make SHARED=1 CFLAGS=-fPIC
make DESTDIR=/usr install
popd
ldconfig

# clean directory
rm -rf /tmp/shadowsocks-libev

# compile and install
cd /tmp
git clone https://github.com/shadowsocks/shadowsocks-libev.git
cd shadowsocks-libev
git submodule update --init --recursive
./autogen.sh
./configure
make
make install
cd ..
rm -rf /tmp/shadowsocks-libev

临时提权至 root 执行脚本

$ sudo su
# bash /home/你的用户名/temp/install-shadowsocks-libev.sh

耐心等待一段时间。如网络没啥大问题则不会出错。

创建配置文件 /etc/shadowsocks-libev/config.json，假设内容如下

{
    "server":["0.0.0.0"],
    "mode":"tcp_and_udp",
    "server_port":8899,
    "local_port":1080,
    "password":"xxxyyy",
    "timeout":86400,
    "method":"chacha20-ietf-poly1305"
}

创建 /etc/default/shadowsocks-libev，作为 ss-server 运行时的 变量/配置 定义文件

# Defaults for shadowsocks initscript
# sourced by /etc/init.d/shadowsocks-libev
# installed at /etc/default/shadowsocks-libev by the maintainer scripts

#
# This is a POSIX shell fragment
#
# Note: `START', `GROUP' and `MAXFD' options are not recognized by systemd.
# Please change those settings in the corresponding systemd unit file.

# Enable during startup?
START=yes

# Configuration file
CONFFILE="/etc/shadowsocks-libev/config.json"

# Extra command line arguments
DAEMON_ARGS="-u"

# User and group to run the server as
USER=nobody
GROUP=nobody

# Number of maximum file descriptors
MAXFD=32768

要基于 systemd 管理服务，创建文件 /lib/systemd/system/shadowsocks-libev.service

防火墙放行 8899 tcp/udp

$ sudo firewall-cmd --zone=public --add-port=8899/tcp --permanent && sudo firewall-cmd --zone=public --add-port=8899/udp --permanent && sudo firewall-cmd --reload

使用 systemd 设置开机自启和启动服务

$ sudo systemctl enable shadowsocks-libev
$ sudo systemctl start shadowsocks-libev

使用 $ sudo systemctl status shadowsocks-libev 查看运行状态。
