我正在尝试编写用于自动化/etc/init.d/oracleasm configure命令的代码,因为它需要4个输入才能继续。
Default user to own the driver interface [grid]: grid
Default group to own the driver interface [y]: oinstall
Start Oracle ASM library driver on boot (y/n) [y]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
通常,为实现此目的而编写代码的最佳方法是什么。请建议我。

如果您有一个可以非交互式运行的命令会更好,但您可以使用expect
运行交互式命令。根据您的示例,它将是:
bash 'OracleASM' do
user 'root'
code <<-EOF
/usr/bin/expect -c 'spawn /etc/init.d/oracleasm configure
expect "Default user to own the driver interface [grid]: "
send "grid\r"
expect "Default group to own the driver interface [y]: "
send "oinstall\r"
expect "Start Oracle ASM library driver on boot (y/n) [y]: "
send "y\r"
expect "Scan for Oracle ASM disks on boot (y/n) [y]: "
send "y\r"
expect eof'
EOF
end
成为幂等命令很重要/etc/init.d/oracleasm configure
,这意味着你可以运行一次,两次或一百次,它的行为和结果系统将是相同的。如果不是这种情况,您需要对命令(only_if
或not_if
)进行一些保护,以便在需要时仅运行命令:
bash 'OracleASM' do
user 'root'
code <<-EOF
....
EOF
not_if { ::File.exists?('/...') }
end
