安装libsodium，让服务器支持chacha20等加密方式

用chacha20加密方式需要安装libsodium
注意：libsodium从1.0.15开始就废弃了aes-128-ctr
yum install wget m2crypto git libsodium -y


yum -y groupinstall “Development Tools”
wget https://github.com/jedisct1/libsodium/releases/download/1.0.17/libsodium-1.0.17.tar.gz
tar xf libsodium-1.0.17.tar.gz && cd libsodium-1.0.17

./autogen.sh
./configure && make -j2 && make install
echo /usr/local/lib > /etc/ld.so.conf.d/usr_local_lib.conf
ldconfig
