在研发过程当中,不断的有项目或者产品升级,在此过程当中,咱们能够充分利用shell脚本去实现一些固定步骤的一键部署和升级。linux
在编写脚本前,咱们能够编写一个额外的配置文件做为一键部署的入参文件,脚本能够读取到该配置文件中的变量值。届时,只须要修改配置文件内的配置,而无需更改脚本。
如:test.propertiesshell
[root@linux01 ~/test_sh]# vim test.properties # set parameters start # int type id_test=12 # string type str_test="test properties" # array with white space type array_test=(arr1 arr2 arr3)
[root@linux01 ~/test_sh]# ll -rw-r----- 1 root root 159 Mar 16 21:43 test.properties
[root@linux01 ~/test_sh]# vim test.sh #!/bin/bash # print start time starttime=$(date +%Y-%m-%d\ %H:%M:%S) # echo to log echo "【Start to execute the script】, start time is: " $starttime >> test_sh.log # read properties from other file source ./test.properties echo "Parameters: cat test.properties" >> test_sh.log while read line do echo $line >> test_sh.log; done < test.properties echo "------ test.properties end------" >> test_sh.log # ============================================================== # create dir mkdir ${str_test}${id_test} echo -e "\nmkdir dir success, and name is: "${str_test}${id_test} >> test_sh.log # product file for ((i=0; i<${#array_test[@]}; i++)) do echo "now array_test i is "${#array_test[@]} >> test_sh.log echo "This is ${array_test[i]} file " >> ${array_test[i]}_file.txt done # print end time endtime=`date +"%Y-%m-%d %H:%M:%S"`
[root@linux01 ~/test_sh]# ll -rw-r----- 1 root root 159 Mar 16 21:43 test.properties -rwxr-x--- 1 root root 993 Mar 16 21:45 test.sh
注意为了简化,咱们将test.properties
和test.sh
放到一个目录下,以便于读取配置。vim
[root@linux01 ~/test_sh]# sh test.sh [root@linux01 ~/test_sh]# ll total 28 -rw-r----- 1 root root 19 Mar 16 22:11 arr1_file.txt -rw-r----- 1 root root 19 Mar 16 22:11 arr2_file.txt -rw-r----- 1 root root 19 Mar 16 22:11 arr3_file.txt -rw-r----- 1 root root 159 Mar 16 22:08 test.properties drwxr-x--- 2 root root 4096 Mar 16 22:11 test_properties12 -rwxr-x--- 1 root root 969 Mar 16 22:11 test.sh -rw-r----- 1 root root 469 Mar 16 22:11 test_sh.log
