Linux Centos7 上安装consul

Linux Centos7 上安装consul

1.下载

wget https://releases.hashicorp.com/consul/0.7.5/consul_0.7.5_linux_amd64.zip 

[root@localhost soft]# wget  https://releases.hashicorp.com/consul/0.7.5/consul_0.7.5_linux_amd64.zip --2017-07-02 19:01:02--  https://releases.hashicorp.com/consul/0.7.5/consul_0.7.5_linux_amd64.zipResolving releases.hashicorp.com (releases.hashicorp.com)... 151.101.73.183, 2a04:4e42:11::439Connecting to releases.hashicorp.com (releases.hashicorp.com)|151.101.73.183|:443... failed: Connection timed out.Connecting to releases.hashicorp.com (releases.hashicorp.com)|2a04:4e42:11::439|:443... failed: Network is unreachable.[root@localhost soft]# wget https://releases.hashicorp.com/consul/0.7.5/consul_0.7.5_linux_amd64.zip --2017-07-02 19:04:23--  https://releases.hashicorp.com/consul/0.7.5/consul_0.7.5_linux_amd64.zipResolving releases.hashicorp.com (releases.hashicorp.com)... 151.101.73.183, 2a04:4e42:11::439Connecting to releases.hashicorp.com (releases.hashicorp.com)|151.101.73.183|:443... connected.HTTP request sent, awaiting response... 200 OKLength: 8764587 (8.4M) [application/zip]Saving to: 鈥榗onsul_0.7.5_linux_amd64.zip鈥100%[==================================================================================================================================================================================================>] 8,764,587   59.4KB/s   in 3m 31s 2017-07-02 19:07:55 (40.7 KB/s) - 鈥榗onsul_0.7.5_linux_amd64.zip鈥saved [8764587/8764587][root@localhost soft]# ll

2.解压

unzip consul_0.7.5_linux_amd64.zip

就会在当前目下看到consul文件

  inflating: consul                  [root@localhost soft]# lltotal 44540-rwxr-xr-x. 1 root root 36003713 Feb 14 20:15 consul-rw-r--r--. 1 root root  8764587 Mar  1 08:50 consul_0.7.5_linux_amd64.zip

3.执行以下 ./consul 出现以下信息就说明安装成功

[root@localhost soft]# ./consulusage: consul [--version] [--help] <command> [<args>]Available commands are:    agent          Runs a Consul agent    configtest     Validate config file    event          Fire a new event    exec           Executes a command on Consul nodes    force-leave    Forces a member of the cluster to enter the "left" state    info           Provides debugging information for operators    join           Tell Consul agent to join cluster    keygen         Generates a new encryption key    keyring        Manages gossip layer encryption keys    kv             Interact with the key-value store    leave          Gracefully leaves the Consul cluster and shuts down    lock           Execute a command holding a lock    maint          Controls node or service maintenance mode    members        Lists the members of a Consul cluster    monitor        Stream logs from a Consul agent    operator       Provides cluster-level tools for Consul operators    reload         Triggers the agent to reload configuration files    rtt            Estimates network round trip time between nodes    snapshot       Saves, restores and inspects snapshots of Consul server state    version        Prints the Consul version    watch          Watch for changes in Consul

4.启动consul

我的linux ip地址为:10.11.3.161

 ./consul agent -dev -ui -node=consul-dev -client=10.11.3.161

出现以下信息，说明consul已在启动

然后在虚拟机浏览器中输 http://10.11.3.161:8500 就看到以下图：

然后我在本机上访问consul 发现访问不了，后发现centos的防火墙比较严，8500端口没有打开，执行以下命令即行：

[root@localhost soft]# firewall-cmd --zone=public --add-port=8500/tcp --permanent  

[root@localhost soft]# systemctl stop firewalld.service [root@localhost soft]# systemctl start firewalld.service 

这样再启动consul，就可以访问了
