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。 ZYXW、参考 1、官网doc http://docs.saltstack.com/en/latest/ref/states/all/salt.states.file.html
