# Run MySQL on Occlum
[`MySQL`](https://www.mysql.com/) is a widely used open-source relational database management system (RDBMS).
### Preinstall dependencies
Related dependencies: libnuma-dev libboost-all-dev boost-1.77.0
```
./preinstall_deps.sh
```
### Download and build MySQL
```
./dl_and_build_mysql.sh
```
This command downloads MySQL-8.0.31 source code and builds from it.
When completed, all MySQL related binaries and tools are installed.
### Run server and client
#### Initialize and start the MySQL server
```
./run_mysql_server.sh
```
This command initializes and runs the server (using `mysqld`) in Occlum.
When completed, the server starts to wait connections.
#### Start the MySQL client and send simple queries
```
./run_mysql_client.sh
```
This command starts the client (using `mysql`) in Occlum and test basic query SQLs.
The network protocol between client and server uses uds(unix domain socket) by default.
More configuration can be tuned and applied in `my.cnf`.
