SSL证书签发

按照架构设计，在hdss7-12，hdss7-21, hdss7-22三台上部署etcd服务：

首先创建etcd用户：

# useradd -s /sbin/nologin -M etcd

创建应用包存放目录

# mkdir -p /opt/src
# cd /opt/src

下载etcd组件：

地址：https://github.com/etcd-io/etcd/tags

# wget https://github.com/etcd-io/etcd/releases/download/v3.2.28/etcd-v3.2.28-linux-amd64.tar.gz
# tar -zxf etcd-v3.2.28-linux-amd64.tar.gz -C ../
# ln -s /opt/etcd-v3.2.28-linux-amd64/ /opt/etcd
# mkdir -p /opt/etcd/certs /data/etcd /data/logs/etcd-server

编辑etcd启动脚本：


# vim /opt/etcd/etcd-server-startup.sh

标红处在另外两台服务器上需要修改成对应自己的ip地址：

#!/bin/sh
./etcd --name etcd-server-7-12 \
       --data-dir /data/etcd/etcd-server \
       --listen-peer-urls https://10.4.7.12:2380 \
       --listen-client-urls https://10.4.7.12:2379,http://127.0.0.1:2379 \
       --quota-backend-bytes 8000000000 \
       --initial-advertise-peer-urls https://10.4.7.12:2380 \
       --advertise-client-urls https://10.4.7.12:2379,http://127.0.0.1:2379 \
       --initial-cluster  etcd-server-7-12=https://10.4.7.12:2380,etcd-server-7-21=https://10.4.7.21:2380,etcd-server-7-22=https://10.4.7.22:2380 \
       # --ca-file ./certs/ca.pem \
       # --cert-file ./certs/etcd-peer.pem \
       --key-file ./certs/etcd-peer-key.pem \
       --client-cert-auth  \
       --trusted-ca-file ./certs/ca.pem \
       --peer-ca-file ./certs/ca.pem \
       --peer-cert-file ./certs/etcd-peer.pem \
       --peer-key-file ./certs/etcd-peer-key.pem \
       --peer-client-cert-auth \
       --peer-trusted-ca-file ./certs/ca.pem \
       --log-output stdout

添加执行权限：

# chmod +x /opt/etcd/etcd-server-startup.sh

创建证书存放目录：

# mkdir /opt/etcd/certs

# cd /opt/etcd/certs

拷贝证书：

# scp hdss7-200:/opt/certs/ca.pem ./
# scp hdss7-200:/opt/certs/etcd-peer.pem ./
# scp hdss7-200:/opt/certs/etcd-peer-key.pem ./

给目录授权：

# chown -R etcd.etcd /opt/etcd/certs /data/etcd /data/logs/etcd-server

安装supervisor管理服务

# yum install supervisor -y

启动服务：

# systemctl start supervisord 
# systemctl enable supervisord

编辑etcd启动脚本：红色部分根据主机修改

# vi /etc/supervisord.d/etcd-server.ini

更新supervisord

# supervisorctl update

检查状态：

# supervisorctl status
