Making bash the default shell
• Globally: Set ibmpaseforshell variable

• For your user: edit ~/.profile. On v7.1:
# detect if we're in a PASE shell
/QSYS.LIB/QSHELL.LIB/UNAME.PGM > /dev/null 2>&1
if [ $? != 0 -a "$SHELL" != "/QOpenSys/usr/bin/bash" ]
then
exec /usr/bin/bash
fi

Create a welcoming development environment on IBM iAlan Seiden Consulting Local development (PC) • Developer codes and tests on her/his PC • Requirement options for testing § Copy of database (difficult for IBM i) § Connection to IBM i database (live data testing) • Requires “DB2 Connect” product • Workflow that deploys to the IFS eventually for production or QA 12
- 13. Create a welcoming development environment on IBM iAlan Seiden Consulting Development on IFS Could use Zend Studio remote server connection 13

- 17. Create a welcoming development environment on IBM iAlan Seiden Consulting Secure shell (ssh) • Provides a fast, secure means to transfer files and submit command to remote servers • Runs as a server program, the SSH daemon (sshd) • One step creates public/private keys and starts server: > STRTCPSVR *SSHD • Verify that sshd is running with > NETSTAT *CNN Look for local port called “ssh” or 22 • If sshd isn’t listed, make sure the QUSRWRK subsystem is running and try again > STRSBS SBSD(QUSRWRK) > STRTCPSVR *SSHD 17

- 30. Create a welcoming development environment on IBM iAlan Seiden Consulting Tips for PHP-CLI • To ensure success § Navigate to PHP’s “bin” directory where php-cli is located • cd /usr/local/zendsvr6/bin • Specify php-cli explicitly; “php” will not work in all versions • PHP-CLI on IBM i vs. other systems § On IBM i, php-cli is a shell script that sets up paths for PHP § On Linux, Windows, et al., php-cli is an actual executable file § php-cli -n is faster because it bypasses php.ini and loading extensions 30
