硬件環(huán)境：
3臺(tái)32G內(nèi)存服務(wù)器
操作系統(tǒng)：
centos7-1511
網(wǎng)卡配置为朋，保證服務(wù)器都可以訪問(wèn)外網(wǎng)：
TYPE=Ethernet
BOOTPROTO=static
DEVICE=eno1
ONBOOT=yes
IPADDR=192.168.144.104
NETMASK=255.255.252.0
DNS1=127.0.0.1
DNS2=114.114.114.114
GATEWAY=192.168.147.254
關(guān)閉防火墻宇整，關(guān)閉selinux
安裝epel源阴绢，三臺(tái)服務(wù)器都操作
yum -y install epel-release
/etc/hosts偏灿，三臺(tái)服務(wù)器同樣配置:
192.168.144.104 server1
192.168.144.105 server2
192.168.144.108 server3
192.168.144.104 jobs.blueking.com
192.168.144.104 cmdb.blueking.com
192.168.144.104 paas.blueking.com
配置主機(jī)名穿扳，server1,server2,server3
配置免密登陸（方法一）
Step1 三臺(tái)服務(wù)器上，ssh-keygen三次回車
Step2 將三個(gè)服務(wù)器下面的.ssh/id_rsa.pub中的公鑰收集到server1的.ssh/authorized_keys
[root@server1 ~]# cat .ssh/id_rsa.pub > .ssh/authorized_keys
[root@server2 ~]# cat .ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDPJdc5o/LzAWD+8t2iZNR31011KqorynNvUkP6VlMvkISy6xN8Eqn90irxo4EHRzxLwflsNUv6VvC4DGi2aCkQEtarTCmN6UGPg2lPiMBZjqCH4fX5Fv1pAYlQWqxqoAmCZ3nmWSQlpXNNStcx4IDx8X9fI5MTS7Qx+URG5VJoSG5nY8sbX9KyK/sGwRvqJvGedLw+crop+/ze+C9sDAkHucbeIKRSzy9P72eHrKqiHDp5YUmHw3z57TLHXA1LGkgAJOTf3tVWnp58F8RUZ5koCs/BCz6wHAyZ0dFqhFMUY8cd4AspfJbNSRXzIDk4vvbOFUDnJ8FjwSuM5CX0Rh51 root@server2
...
[root@server1 ~]# cat .ssh/authorized_keys

Step3 將server1中的authorized_keys公鑰復(fù)制到server2,server3中
[root@server1 ~]# scp .ssh/authorized_keys server3:~/.ssh/
root@server3's password:
authorized_keys 100% 1182 1.2KB/s 00:00
[root@server1 ~]# scp .ssh/authorized_keys server2:~/.ssh/
root@server2's password:
authorized_keys 100% 1182 1.2KB/s 00:00
配置免密登陸（方法二）
ssh-keygen -t rsa -b 2048
cat /root/.ssh/id_rsa.pub >/root/.ssh/authorized_keys
chmod 600 /root/.ssh/authorized_keys
for ip in $(awk '{print $1}' install.config); do
rsync -a /root/.ssh/authorized_keys root@$ip:/root/.ssh/
done
使用阿里pip源
[root@server1 ~]# cat /data/src/.pip/pip.conf
[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
trusted-host = mirrors.aliyun.com
三臺(tái)服務(wù)器上安裝Development Tools
# yum group list
# yum -y groupinstall "Development Tools"
配置三臺(tái)服務(wù)器時(shí)間同步
# ntpdate -u cn.pool.ntp.org
# timedatectl set-timezone Asia/Shanghai 執(zhí)行完后時(shí)間就變?yōu)楸本r(shí)間了
余下步驟參考官網(wǎng)文檔
