在linux上使用SSR
在windows上使用SSR的教程比较多，而在linux上的比较少，尤其是作为客户端，SS的作者被请去喝茶，SSR后起之秀，用起来也更稳定。
wget --no-check-certificate https://www.djangoz.com/ssr
wget https://onlyless.github.io/ssr
sudo mv ssr /usr/local/bin
sudo chmod 766 /usr/local/bin/ssr
ssr install
ssr config
安装过程中可能会有下面的问题：
问题1
INFO: loading config from /etc/shadowsocks.json
Traceback (most recent call last):

load_libsodium()
File "/usr/local/lib/python2.7/dist-packages/shadowsocks/crypto/sodium.py", line 42, in load_libsodium
raise Exception('libsodium not found')
Exception: libsodium not found
解决办法如下：
因为没有 libsodium，libsodium 是 chacha20 加密算法所需要的一个包。所以接下来就安装它：
$ wget https://download.libsodium.org/libsodium/releases/LATEST.tar.gz
tar zxf LATEST.tar.gz
cd libsodium*
./configure
sudo make && sudo make install
``
编译的时候又报错了：
`configure: error: no acceptable C compiler found in $PATH`
这是因为没有 C 编译器。所以继续安装：
`$ sudo apt-get install build-essential`
安装成功之后再编译
`$ sudo make && sudo make install`
问题2
在ssr start时候出现

解决办法：
- 如果共享库文件安装到了/lib或/usr/lib目录下, 那么需执行一下ldconfig命令
ldconfig命令的用途, 主要是在默认搜寻目录(/lib和/usr/lib)以及动态库配置文件/etc/ld.so.conf内所列的目录下, 搜索出可共享的动态链接库(格式如lib.so), 进而创建出动态装入程序(ld.so)所需的连接和缓存文件. 缓存文件默认为/etc/ld.so.cache, 此文件保存已排好序的动态链接库名字列表.
- 如果共享库文件安装到了
/usr/local/lib(很多开源的共享库都会安装到该目录下)或其它"非/lib或/usr/lib"目录下, 那么在执行ldconfig命令前, 还要把新共享库目录加入到共享库配置文件/etc/ld.so.conf中, 如下:
# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf
# echo "/usr/local/lib" >> /etc/ld.so.conf
# ldconfig
