saltstack的深入-增加针对系统调优的state配置

saltstack的深入-增加针对系统调优的state配置

一、基础环境
1、在tvm-saltmaster的基础上操作。
2、网络:
eth0:host-only(用于虚拟内网,手动固定IP,这样从宿主机可以直接连接到这个vm)
eth1:NAT(用于上外网,动态IP)
[root@tvm-saltmaster ~]# cd /etc/sysconfig/network-scripts/
[root@tvm-saltmaster network-scripts]# cat ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.56.253
PREFIX=24
GATEWAY=192.168.56.1
DNS1=192.168.56.254

[root@tvm-saltmaster network-scripts]# cat ifcfg-eth1
DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
DNS1=192.168.56.254


二、针对limits,sysctl,rc.local,modprobe做一些配置
1、sls文件
[root@tvm-saltmaster base]# cat abc/init.sls 
include:
  - abc.hosts
  - abc.resolv
  - abc.yum
  - abc.packages
  - abc.systemtuning
[root@tvm-saltmaster base]# cat abc/systemtuning.sls 
## update sysctl
# 
# via pc @ 2015/8/12

basic-limits:
  file.managed:
    - name: /etc/security/limits.d/my-limits.conf
    - source: salt://conf.d/systemtuning/my-limits.conf

basic-sysctl:
  file.append:
    - name: /etc/sysctl.conf
    - source: salt://conf.d/systemtuning/sysctl.conf

basic-rc-local:
  file.append:
    - name: /etc/rc.local
    - source: salt://conf.d/systemtuning/rc-local.conf

basic-modprobe-dist:
  file.append:
    - name: /etc/modprobe.d/dist.conf
    - source: salt://conf.d/systemtuning/modprobe-dist.conf
    
    
2、conf文件 
[root@tvm-saltmaster base]# tail -n 100 conf.d/systemtuning/*      
==> conf.d/systemtuning/modprobe-dist.conf <==

## user define
alias net-pf-10 off
alias ipv6 off

==> conf.d/systemtuning/my-limits.conf <==

## user define
*          soft    nofile    65535
*          hard    nofile    65535
*          soft    nproc     unlimited
*          hard    nproc     unlimited
*          soft    core      unlimited

==> conf.d/systemtuning/rc-local.conf <==

## user define
ulimit -SHn 65535

==> conf.d/systemtuning/sysctl.conf <==

## user define
fs.file-max = 51200

net.core.rmem_max = 8388608
net.core.wmem_max = 8388608
net.core.rmem_default = 65536
net.core.wmem_default = 65536
net.core.netdev_max_backlog = 250000
net.core.somaxconn = 4096

net.ipv4.ip_local_port_range = 10000 65000
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 0
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_time = 1200

net.ipv4.tcp_max_syn_backlog = 8192
net.ipv4.tcp_max_tw_buckets = 5000
net.ipv4.tcp_rmem = 4096 87380 8388608
net.ipv4.tcp_wmem = 4096 65536 8388608
net.ipv4.tcp_mem = 8388608 8388608 8388608


三、总结
此处用到了以下方法:
file.managed
file.append

执行:
[root@tvm-saltmaster base]# salt 'tvm-test' state.sls abc.systemtuning --output-file='/tmp/salt.log'  
或者:
[root@tvm-saltmaster base]# salt '*' state.highstate --output-file='/tmp/salt.log' 
查看结果:
[root@tvm-saltmaster base]# more /tmp/salt.log 


备注:上述所谓调优参数仅做参考,根据实际的业务场景来配置,切忌直接套用。
