一、創(chuàng)建centos7.6系統(tǒng)并優(yōu)化系統(tǒng)

1.關(guān)閉NetworkManager

systemctl disable NetworkManagersystemctl stop NetworkManager

2.關(guān)閉selinux

setenforce 0sed -i "s#SELINUX=enforcing#SELINUX=disabled#g" /etc/selinux/config

3.關(guān)閉firewalld

systemctl stop firewalldsystemctl disable firewalld

4.安裝日常需要用的軟件

yum install vim nc wget lrzsz telnet net-tools epel-release bind-utils tree cifs-utils ntpdate -y

5.修改網(wǎng)絡(luò)配置（改為/etc/sysconfig/network-scripts/ifcfg-eth0）及多網(wǎng)卡配置

###修改網(wǎng)卡文件名和配置cd /etc/sysconfig/network-scriptscp ifcfg-ens192 /tmp/ifcfg-ens192_baksed -i "s#NAME=.*#NAME='eth0'#g" ifcfg-ens192sed -i "s#DEVICE=.*#DEVICE='eth0'#g" ifcfg-ens192mv ifcfg-ens192 ifcfg-eth0###修改grub配置sed -i 's#GRUB_CMDLINE_LINUX=.*#GRUB_CMDLINE_LINUX=/"rhgb quiet net.ifnames=0 biosdevname=0/"#g' /etc/default/grubgrub2-mkconfig -o /boot/grub2/grub.cfg

6.修改所有用戶的最大文件數(shù)

#cat >> /etc/security/limits.conf <<eof*    soft  nofile 65535eof#cat >> /etc/security/limits.conf <<eof*    hard  nofile 65535eof

7.修改普通用戶的最大進(jìn)程數(shù)

#sed -i "/*/s#*     soft  nproc.*#*     soft  nproc   65535#g" /etc/security/limits.d/20-nproc.conf

二、導(dǎo)出centos7 ova模板并修改模板文件

1.用ovftool工具導(dǎo)出(由于瀏覽器不支持大文件導(dǎo)出)

1）下載ovftool工具
https://www.vmware.com/support/developer/ovf/

2）安裝ovftool工具
雙擊VMware-ovftool-4.3.0-7948156-win.x86_64.msi，默認(rèn)下一步，完成即可

3）用ovftool命令導(dǎo)出ova模板

PS >cd C:/Program Files/VMware/VMware OVF ToolPS >./ovftool.exe -dm=thin "vi://10.10.90.239/centos-template" d:/centos-template/centos-template.ova #10.10.90.239為宿主機(jī)ipFingerprint will be added to the known host fileWrite 'yes' or 'no'yes #輸入yesEnter login information for source vi://10.10.90.239/Username: root #用戶名Password: ********* #密碼Opening VI source: vi://root@10.10.90.239:443/centos-templateOpening OVA target: d:/centos-template/centos-template.ovaWriting OVA package: d:/centos-template/centos-template.ovaTransfer CompletedCompleted successfully

2.修改ova模板里文件
1）將centos-template.ova后綴名改為centos-template.rar
2）解壓縮centos-template.rar
3）刪除centos-template.mf和centos-template.nvram
4）修改centos-template.ovf文件，將帶有nvram字符的兩行刪除掉，保存文件

三.導(dǎo)入ovf模板

打開瀏覽器-->進(jìn)入vmware esxi6.7 宿主機(jī)頁(yè)面 --> 虛擬機(jī) --> 創(chuàng)建/注冊(cè)虛擬機(jī) --> 從OVF或OVA文件部署虛擬機(jī) --> test-centos-template（為該虛擬機(jī)輸入名稱。）--> 單擊以選擇文件或拖放（將centos-template.ovf和centos-template-disk1.vmdk兩個(gè)文件拖放到此區(qū)域） --> 默認(rèn)下一頁(yè) -->完成
