Vim-LatexSuite:/bin/bash: латекс command not found

TeXLive 2015: I installed TeXLive 2015 following the simplest instruction sudo ./install-tl-ubuntu (without any options) of scottkosty/install-tl-ubuntu@GitHub.

Vim-Latex-Suite: I installed Vim-Latex-Suite following these Инстальятион Инструктионс, including these recommended settings.

However, \ll (to я составил .tex in Latex-Suite) does not work.
The command :!latex -interaction=nonstopmode % шоу

/bin/bash: latex: command not found
shell returned 127    

My current configurations:

echo $PATH in ubuntu шоу:

/opt/texbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

:echo $PATH in vim шоу:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

which latex шоу /opt/texbin/latex;
and latex --version шоу

Two methods which do not work:

1. Adding export PATH=$PATH:/opt/texbin/ to file .bashrc

2. The method from ТЕКС Ливе and vim-latexsuite PATH problems does not work for я:

   $ cat /etc/profile.d/latex.sh  
   export PATH="${PATH}:/usr/local/texlive/2015/bin/x86_64-linux"
   

ADDED: By the way, in my another Ubuntu system with латекс installed in another way, which latex gives /usr/bin/latex and vim-latex works.
