1.编写salt配置文件
[root@master state]# tree
├── sysctl
└── init.sls
[root@master sysctl]# cat init.sls
net.ipv4.ip_forward:
sysctl.present:
- name: net.ipv4.ip_forward
- value: 0
net.ipv4.tcp_syn_retries:
sysctl.present:
- name: net.ipv4.tcp_syn_retries
- value: 1
net.ipv4.tcp_tw_recycle:
sysctl.present:
- name: net.ipv4.tcp_tw_recycle
- value: 1
net.ipv4.tcp_tw_reuse:
sysctl.present:
- name: net.ipv4.tcp_tw_reuse
- value: 1
2.执行命令推送
[root@master sysctl]# salt minion02 state.sls state.sysctl

3.在minion02端查看
[root@minion02 ~]# cat /etc/sysctl.d/99-salt.conf
#
# Kernel sysctl configuration
#
net.ipv4.ip_forward = 0
net.ipv4.tcp_syn_retries = 1
