SUSE 上的 etcd

现在，没有可用于etcd3的软件包。 本指南使用tarball安装作为解决方法，直到有合适的软件包为止。

The etcd service runs on the controller node.

安装并配置组件

1. 安装 etcd:

   • 创建 etcd 用户:

     # groupadd --system etcd
     # useradd --home-dir "/var/lib/etcd" \
           --system \
           --shell /bin/false \
           -g etcd \
           etcd
     

   • 创建所需的目录:

     # mkdir -p /etc/etcd
     # chown etcd:etcd /etc/etcd
     # mkdir -p /var/lib/etcd
     # chown etcd:etcd /var/lib/etcd
     

   • Determine your system architecture:

     # uname -m
     

   • Download and install the etcd tarball for x86_64/amd64:

     # ETCD_VER=v3.2.7
     # rm -rf /tmp/etcd && mkdir -p /tmp/etcd
     # curl -L \
           https://github.com/coreos/etcd/releases/download/${ETCD_VER}/etcd-${ETCD_VER}-linux-amd64.tar.gz \
           -o /tmp/etcd-${ETCD_VER}-linux-amd64.tar.gz
     # tar xzvf /tmp/etcd-${ETCD_VER}-linux-amd64.tar.gz \
           -C /tmp/etcd --strip-components=1
     # cp /tmp/etcd/etcd /usr/bin/etcd
     # cp /tmp/etcd/etcdctl /usr/bin/etcdctl
     

     Or download and install the etcd tarball for arm64:

     # ETCD_VER=v3.2.7
     # rm -rf /tmp/etcd && mkdir -p /tmp/etcd
     # curl -L \
           https://github.com/coreos/etcd/releases/download/${ETCD_VER}/etcd-${ETCD_VER}-linux-arm64.tar.gz \
           -o /tmp/etcd-${ETCD_VER}-linux-arm64.tar.gz
     # tar xzvf /tmp/etcd-${ETCD_VER}-linux-arm64.tar.gz \
           -C /tmp/etcd --strip-components=1
     # cp /tmp/etcd/etcd /usr/bin/etcd
     # cp /tmp/etcd/etcdctl /usr/bin/etcdctl
     

2. 创建并编辑 /etc/etcd/etcd.conf.yml 文件，设置 initial-cluster 、 initial-advertise-peer-urls 、 advertise-client-urls 、 listen-client-urls 为控制节点的管理 IP 地址，以允许其他节点通过管理网络访问。

   name: controller
   data-dir: /var/lib/etcd
   initial-cluster-state: 'new'
   initial-cluster-token: 'etcd-cluster-01'
   initial-cluster: controller=http://10.0.0.11:2380
   initial-advertise-peer-urls: http://10.0.0.11:2380
   advertise-client-urls: http://10.0.0.11:2379
   listen-peer-urls: http://0.0.0.0:2380
   listen-client-urls: http://10.0.0.11:2379
   

3. 创建并编辑 /usr/lib/systemd/system/etcd.service 文件:

   [Unit]
   After=network.target
   Description=etcd - highly-available key value store
   
   [Service]
   # Uncomment this on ARM64.
   # Environment="ETCD_UNSUPPORTED_ARCH=arm64"
   LimitNOFILE=65536
   Restart=on-failure
   Type=notify
   ExecStart=/usr/bin/etcd --config-file /etc/etcd/etcd.conf.yml
   User=etcd
   
   [Install]
   WantedBy=multi-user.target
   

   重新载入 systemd 服务文件:

   # systemctl daemon-reload
   

完成安装

1. 启用并启动 etcd 服务:

   # systemctl enable etcd
   # systemctl start etcd
