Currently this role is not compatible with ProxySQL >= v2.0.1.
This role is just compatible with Ansible 2.7.9 or higher due to a bug in the migration from MySQLdb to PyMySQL (#40123) in the MySQL module utils.
Release 0.3.0 is compatible with Ansible 2.7.0 or lower.
This role installs and configures ProxySQL - the high performance, high availability, protocol aware proxy for MySQL.
Since version 2.3.0 Ansible is providing an module to configure ProxySQL itself. This Ansible role is using this functionality but adding some (hopefully useful) features on top:
- Automatic installation for different operating systems
- (Pre-) generation of proxysql.cnf
- Manage a ProxySQL-Cluster (with a custom module which adds the functionality to configure ProxySQL servers)
- Differentiate between dynamic and static
global_variables- restart ProxySQL if required
Please also take a look at the "Known issues or: Good to know" section in this document.
This role requires Ansible 2.5.0 or higher.
You can simply use pip to install (and define) a stable version:
pip install ansible==2.7.9All platform requirements are listed in the metadata file.
ansible-galaxy install timorunge.proxysqlThe variables that can be passed to this role. For all variables, take a look at defaults/main.yml.

...On Ubuntu 16.04 Ansible (version does not matter) / ProxySQL > 1.4.7 seems
to have problems to communicate correctly via mysql-python /
python-mysqldb.
Example error:
"unable to modify server.. (1045, 'unrecognized token: \"\\'\\n AND compression = 0\\n AND weight = 1\\n AND use_ssl = 0\\n AND max_connections = 2000\\n AND max_latency_ms = 0\\n AND max_replication_lag = 5\"')"Note:
I've done the following little research with mysql-python installed via pip
on Ubuntu 16.04. Don't worry, it's also failing with python-mysqldb.
In the MySQLdb python library the execute method (class BaseCursor) is
generating a query in the following way:
query = query % tuple([db.literal(item) for item in args])db.literal is part of the Connection class and returns single objects as a
string and mutliple objects as a sequence while it's converting each sequence
as well.
def literal(self, o):
# ...
return self.escape(o, self.encoders)self.escape
should escape all special characters in the given object and is using a mapping
dict to provide quoting functions for each type. This is self.encoders which -
per default and not set different - using MySQLdb.converters.
The mapping for a string is StringType: Thing2Literal. So the string will be
escaped with the method Thing2Literal.
def Thing2Literal(o, d):
# ...
return string_literal(o, d)string_literal
should convert our string object into a SQL string literal. This means, any
special SQL characters are escaped, and it is enclosed within single quotes.
In other words, it performs:
"'%s'" % escape_string(str(obj))During escaping the string the string objects are getting deleted and are
returning just a single quote (').
Since in the tests nothing beside the version of ProxySQL changed I assume that a change in ProxySQL (diff 1.4.7 vs. 1.4.8) is causing Ansible to fail. Because ProxySQL itself - if not triggered via Ansible - is working perfectly fine.
Last but not least...
This issue is sorted by installing mysqlclient - which is a fork of MySQLdb - via pip.
ProxySQL itself is not providing "up to date" packages for Ubuntu > 16.04. This Ansible role is working around this by downloading the 16.04 release for Ubuntu > 16.04 and installing the same (this behavoir might change in the future).
There is a package dependency for libcrypto++6 and libssl1.0.0 starting
from Ubuntu >= 18.04 (which is sorted out automatically).
ProxySQL has some global_variables which can't be changed during runtime
(see proxysql_non_dynamic_variables in vars/main.yml).
Having said that, this alone is not a problem since this ProxySQL role is
taking care (by generating proxysql.cnf) and provides the possibility to
restart automatically if such a variable will change (set
proxysql_restart_on_static_variables_change to True).
This role is also setting this value in the ProxySQL database itself and here the problem begins:
If you're changing more than one static variable technically everything is OK.
ProxySQL is restarting and taking the new value from proxysql.cnf. But just
the first value is changed in the database itself.
It's not an "big issue" since the real value is taken correctly from the configuration file itself but you'll see a changeset in the next Ansible run which will:
- Restart ProxySQL once again
- Idempotence tests will fail (if you're not bootstrapping from scratch)
A potential solution could be to not set proxysql_non_dynamic_variables in
the ProxySQL database.
The ProxySQL clustering is still experimental. A quote from the clustering documentation: "because this feature is still experimental, the table is not automatically loaded from disk".
For the initialisation from the proxysql.cnf it's important that hostname
(obviously) and port (it's not taking the default value) are defined.
...is not working because of some dependency issues.
Technically we need the following packages to apply Ansible correctly:
proxysql_dependency_pkgs:
- MySQL-python
- mysqlWith the enabled Percona repository the package dependencies for MySQL-python
and mysql are clashing.
