 Description   

I've installed MaxScale 1.2.0 on Centos 7.1.1503 this morning. I've noticed an issue with maxadmin though: i can't use the up arrow to access old commands that have been typed in.

You can see the attached screenshot to see what happens.

Also, I currently have libedit-3.0-12.20121213cvs.el7.x86_64 installed.

libedit needs to be installed on he build machine in order for the command history to work.

failshell Can you try again with 1.2.1?

Comment by Jean-Francois Theroux [ 2015-11-02 ]

Sadly, I get the same error.

What is the ldd output for your installation's maxadmin?

For comparison, here is one from a CentOS 7 VM with MaxScale 1.2.1:

[root@localhost etc]# ldd /bin/maxadmin
 
	linux-vdso.so.1 =>  (0x00007fff54f96000)
 
	libedit.so.0 => /lib64/libedit.so.0 (0x00007f9080f6d000)
 
	libc.so.6 => /lib64/libc.so.6 (0x00007f9080bab000)
 
	libtinfo.so.5 => /lib64/libtinfo.so.5 (0x00007f9080981000)
 
	/lib64/ld-linux-x86-64.so.2 (0x00007f90811b0000)

The libtinfo.so seems to be provided by ncurses-devel but on the VM the package isn't installed. Can you try installing this package and trying if it fixes your problems?

I installed ncurses-devel and it's stil not working.

Comment by markus makela [ 2015-11-02 ]

Thank you for a quick reply. It seems there is something wrong with the build process for CentOS 7, we'll let you know when we have more information.

Comment by markus makela [ 2016-08-30 ]

Adding readline support for maxadmin is one way to fix this.

Comment by Esa Korhonen [ 2017-01-16 ]

After testing MaxScale 1.4.4 in CentOS 7, it seems MaxAdmin is working as intended. The command history requires that the libedit-devel package is installed when configuring and compiling.

Please upgrade to 1.4.4 and retry.
