    Your mysql path is wrong, try replacing /usr/bin/mysql with /usr/local/bin/mysql or find the propper path of mysql cmd.

    Nice script .

    Probably, your mysql binary isn’t in /usr/bin/ try to find it:
    find / -name mysql
    if you have a different location, change the value in the script:
    ## Path to mysql bins ##

    I ./add_database.sh: line 47: /usr/local/mysql/bin/mysql -u root -h localhost -p’wbzd’ -e “GRANT select,insert ON lijun.* TO lijun@ IDENTIFIED BY ‘lijun’;”: No such file or directory

    I replacing /usr/bin/mysql with /usr/local/mysql/bin/mysql,but the same
    I used: /usr/local/mysql/bin/mysql -h localhost -u root -p’wbzd’ it’s ok
