配置ansible

我本地的机器是archlinux, 先安装ansible

1
paru -S ansible

配置/etc/ansible/hosts, 记录下服务器的IP, 以及普通用户sudo提权密码

1
2
[centos8]
192.168.56.103 ansible_become_pass="sudo_password"

发送自己的ssh公钥到服务器

1
ssh-copy-id -i /home/basi/.ssh/id_rsa.pub basi@192.168.56.103

检测ansible是否配置正确，返回的结果为root则配置正确

1
ansible centos8 -u basi -b --become-user root --become-method sudo -m command -a "whoami"

安装redis

编写安装脚本redis-install.sh

7
#!/bin/bash
cd /opt
wget https://download.redis.io/redis-stable.tar.gz
tar -zxvf redis-stable.tar.gz
cd redis-stable && make install #默认安装到/usr/local/bin
cp redis.conf /usr/local/etc/redis.conf
nohup redis-server /usr/local/etc/redis.conf >>/var/log/redis.log 2>&1 &

执行本地脚本，编译安装redis到服务器

1
ansible centos8 -u basi -b --become-user root --become-method sudo -m script -a "/home/basi/redis-install.sh"

检查是否安装成功，且在运行中

1
ansible centos8 -u basi -b --become-user root --become-method sudo -m shell -a "netstat -tulnp | grep redis-server"

成功运行的结果：
