CentOS 7 安装以及配置

  1. Disable SELINUX

    查看selinux 配置, 注意选择permissive或者disabled

[root@node01 centibox]# cat /etc/sysconfig/selinux # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=enforcing # SELINUXTYPE= can take one of three two values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted

  1. 检查基本环境

    • python (系统自带2.7.5,无pip)
    • node
    • erlang
    • c/c++ (parser) （系统自带gcc 4.8.5)
    • Java (Spark/Hadoop)


  2. 安装pip，shadowsocks，polipo

    #安装epel-release (扩展包, pip 需要)
yum install epel-release
yum -y update

    3.1 配置shadowsocks

    yum install python-setuptools && easy_install pip
#如果发现easy_insall pip 说找不到,可以使用
#yum install python-pip 替代
pip install shadowsocks
mkdir -p /etc/shadowsocks

vi /etc/shadowsocks/config.json
{
"server":"*****",
"server_port":8388,
"local_address": "127.0.0.1",
"local_port":1080,
"password":"*****",
"timeout":600,
"method":"aes-256-cfb",
}

vi /usr/lib/systemd/system/shadowsocks-client.service


[Unit]

After=network.target

[Service]

User=root
Group=root

[Install]
WantedBy=multi-user.target

    3.2 配置polipo

     git clone https://github.com/jech/polipo.git
 make all
 mkdir /etc/polipo
 [root@node01 centibox]# cat /etc/polipo/conf
 proxyAddress = "0.0.0.0"

 socksParentProxy = "127.0.0.1:1080"
 socksProxyType = socks5

 chunkHighMark = 50331648
 objectHighMark = 16384

 serverMaxSlots = 64
 serverSlots = 16
 serverSlots1 = 32

  3. 安装docker

    Docker.com 有一篇详细的文档.

    我选择的是使用脚本安装

    curl -fsSL https://get.docker.com/ | sh

usermod -aG docker centibox

docker run --cpu-shares 5 -m 64m  hello-world

echo  $(docker ps -a -q)
