<bdo id='PLCbb'></bdo><ul id='Rzgss'></ul> - 主機初始化
- 數據盤掛載到/app目錄，參考如下（注意：/dev/sdb替換為對應的數據盤）
sudo mkfs.xfs -f -i attr=2 -l lazy-count=1,sectsize=4096 -b size=4096 -d sectsize=4096 -n ftype=1 /dev/sdb
sudo mkdir -p /app
sudo chmod 777 /app
sudo mount /dev/sdb /app
echo "UUID="`blkid /dev/sdb|cut -d '"' -f2`" /app xfs defaults 0 0" | sudo tee -a /etc/fstab
- jdk解壓到/app下，并且/etc/profile與/etc/bashrc中配置jdk環境變量
sudo tar -zxvf /tmp/jdk-8u221-linux-x64.tar.gz -C /app
echo 'export JAVA_HOME=/app/jdk1.8.0_221' | sudo tee -a /etc/profile
echo 'export JRE_HOME=$''JAVA_HOME/jre' | sudo tee -a /etc/profile
echo 'export CLASSPATH=.:$''JAVA_HOME/jre/lib/rt.jar:$''JAVA_HOME/lib/dt.jar:$''JAVA_HOME/lib/tools.jar' | sudo tee -a /etc/profile

- 新增用戶teledb，并添加sudo權限
sudo useradd teledb
echo '1qaz@WSX' | sudo passwd --stdin teledb
echo "teledb ALL=(ALL) NOPASSWD: ALL" | sudo tee -a /etc/sudoers
