 直接下载预编译包即可，能通过配置实现透明代理
+===== Optimization =====
+==== sysctl ====
+优化sysctl参数，创建、编辑 ''/etc/sysctl.d/10-shadowsocks.conf'' 文件：
+<code - /etc/sysctl.d/10-shadowsocks.conf>
+# max open files
+fs.file-max = 51200

+# default read buffer
+net.core.rmem_default = 65536
+# default write buffer
+net.core.wmem_default = 65536
+# max processor input queue
+net.core.netdev_max_backlog = 4096
+# max backlog
+net.core.somaxconn = 4096
+# resist SYN flood attacks
+net.ipv4.tcp_syncookies = 1
+# reuse timewait sockets when safe
+net.ipv4.tcp_tw_reuse = 1
+# turn off fast timewait sockets recycling
+net.ipv4.tcp_tw_recycle = 0
+# short FIN timeout
+net.ipv4.tcp_fin_timeout = 30
+# short keepalive time
+net.ipv4.tcp_keepalive_time = 1200
+# outbound port range

+# for high-latency network
+net.ipv4.tcp_congestion_control = hybla
+# for low-latency network, use cubic instead
+#net.ipv4.tcp_congestion_control = cubic
+</code>
+重新载入sysctl：
+<code>
+sudo sysctl --system
+</code>
