Linux运维---02.制作trove-redis镜像，

redis-3.2 镜像制作及验证
镜像制作
1.安装redis

yum install redis
yum install epl-release   
yum install python-pip  git gcc
pip2 install redis  
pip2 install hiredis   
vim /etc/redis.conf   
protected-mode no   
systemctl enable redis  

2.源码安装trove-guestagent

useradd -m trove   
Defaults:trove !requiretty  
trove ALL=(ALL) NOPASSWD:ALL  

cd /root/  
git clone https://github.com/openstack/trove.git -b stable/pike    
cd trove   
pip install -r requirements.txt  \
    --index-url http://mirrors.aliyun.com/pypi/simple/ \
    --trusted-host mirrors.aliyun.com  
python setpu.py install 

mkdir -p /etc/trove/conf.d

备注：kolla-ctrl1,kolla-ctrl2,kolla-ctrl3 trove.conf所有配置文件都要修改

vim /etc/kolla/trove-api/trove.conf     
vim /etc/kolla/trove-taskmanager/trove-taskmanager.conf     
添加如下配置文件  
[redis]      
tcp_port = 6379,16379      
volume_support = False      
docker restart trove_api trove_conductor trove_taskmanager
