#### 安装
|
||
|
||
```bash
|
||
# 使用yum部署consul
|
||
yum install -y yum-utils
|
||
yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo
|
||
yum -y install consul
|
||
# 如果yum下载失败，可以直接下载RPM包安装
|
||
wget https://rpm.releases.hashicorp.com/RHEL/7/x86_64/stable/consul-1.13.3-1.x86_64.rpm
|
||
rpm -ivh ./consul-1.13.3-1.x86_64.rpm
|
||
```
|
||
|
||
#### 配置
|
||
|
||
```bash
|
||
vi /etc/consul.d/consul.hcl
|
||
log_level = "ERROR" #日志级别，日志太多可以只打印error日志，不需要可以去掉这行。
|
||
advertise_addr = "192.168.x.x" #填写你的网卡IP，如果启动或运行有报错，可以尝试去掉这行。
|
||
data_dir = "/opt/consul"
|
||
client_addr = "0.0.0.0"
|
||
ui_config{
|
||
enabled = true
|
||
}
|
||
server = true
|
||
bootstrap = true
|
||
acl = {
|
||
enabled = true
|
||
default_policy = "deny"
|
||
enable_token_persistence = true
|
||
}
|
||
```
|
||
|
||
#### 启动服务
|
||
|
||
```bash
|
||
chown -R consul:consul /opt/consul #注意下数据目录的权限。
|
||
systemctl enable consul.service
|
||
systemctl start consul.service
|
||
```
|
||
|
||
### 安装后首次获取登录Token（记录SecretID，即为Consul登录的Token）
|
||
```bash
|
||
consul acl bootstrap|grep SecretID
|
||
```
|
||
|
||
|
||
### 忘记global-management Token，重新生成
|
||
```
|
||
# 记录最后的reset index: xx
|
||
consul acl bootstrap
|
||
|
||
# 进入consul数据目录执行
|
||
echo 13 > acl-bootstrap-reset
|
||
|
||
# 重新创建一个global-management Token
|
||
consul acl bootstrap
|
||
```
|
||
|
||
### consul kv 备份还原
|
||
```
|
||
consul kv export --http-addr=http://127.0.0.1:8500 -token=admin-token '' > consul_kv_bak.json
|
||
consul kv import --http-addr=http://127.0.0.1:8500 -token=admin-token @consul_kv_bak.json
|
||
```
