Need to buy a VPS with root privileges, then it purchased 512 M memory 5 G SSD, 500 G flow / month, 9.99 knife each year, but it seems now that low-cost packages over. Interested friends can look at other companies or other packages of VPS. Some friends said that some very fast, watch YouTube directly to 1440p, but I have not tested, currently my VPS speed can meet my needs, and DO the price is more expensive.
The figure is the use of SS and take IPsec VPN services, for reference only:
After the server purchase, installation CentOS7, because these tutorials are based CentOS7, install a new OS, moving tile union Tell your SSH port and root password, which they can not be customized, if you really want to remember the forgotten You can also reset the root password, or directly using sSH to log online to move bricklayer operation can also be provided, that is, the reaction is relatively slow, so after we commonly ssh login to configure the VPS, Mac is like under the direct use of the terminal, the next win on their own Looking for a tool like ssh.
Login ssh command:
$ Ssh-p vps port number address root @ vpsIP
After the login as equivalent in local operation, you can use various Linux commands to operate.
Configure the firewall
If SSH can not sign, it means the firewall turned off SSH port, you need to log in via SSH online turn off the firewall reconfiguration.
Clear Firewall Configuration
$ Iptables -F
Clear iptabels all entries, while nat did not set, but we will follow the script configuration, do not worry. If SSH login normally do not control the firewall.

$ Firewall-cmd --permanent --add-service = ssh
$ Firewall-cmd --reload
OK, now preparations are in place, the installation source, install a firewall is configured, the next step began to build the service.
Build Shadowsocks Service
This service is the simplest and most commonly used.
$ Yum install m2crypto python-setuptools
$ Easy_install pip
