### Centos 7 初始化 ```shell # 第一次部署 ansible-playbook -i hosts/system_hosts system_init/centos7/centos7.yml --skip-tags clean_op_tags ``` ## 調整配置后再次部署 如果優化后，調整了配置，想再次進行優化，需要修改task下的C7_Clean_Optimiz_Tags.yml文件，注釋不優化的部分 假如想重新同步sysct.conf，注釋其他即可 ``` --- - name: clean optimization tags lineinfile: path: "{{ op_tag }}" state: absent regexp: '.system_init' loop: # - /etc/yum.repos.d/CentOS-Base.repo # - /etc/yum.repos.d/epel.repo # - /etc/locale.conf # - /etc/security/limits.d/20-nproc.conf # - /etc/limits.conf # - /etc/ssh/sshd_config - /etc/sysctl.conf # - /etc/profile.d/ps.sh # - /root/.vimrc # - /etc/fail2ban/jail.conf # - /var/spool/cron/root # - /etc/rc.d/rc.local loop_control: loop_var: op_tag tags: clean_op_tags ``` 簡單說就是清理掉之前優化后的tag，讓程序判斷再次優化 ``` ansible-playbook -i hosts/system_hosts system_init/centos7/centos7.yml ```
