### MySQL'de SSL Ba\u011flant\u0131 Kurulumu ve De\u011fi\u015fkenlerin G\u00f6sterilmesi<\/p>
MySQL, g\u00fcvenli ba\u011flant\u0131lar kurmak ve sunucu de\u011fi\u015fkenlerini y\u00f6netmek i\u00e7in \u00e7e\u015fitli ara\u00e7lar sunar. Bu yaz\u0131da, **SSL ba\u011flant\u0131 kurulumu** ve **SHOW VARIABLES** komutu ile ilgili temel bilgileri ve kullan\u0131m \u00f6rneklerini ele alaca\u011f\u0131z.<\/p>

### SSL Ba\u011flant\u0131 Kurulumu<\/p>
MySQL'de SSL ba\u011flant\u0131lar\u0131, veri ileti\u015fimini \u015fifreleyerek g\u00fcvenli hale getirir. Bu \u00f6zellik, \u00f6zellikle hassas verilerin iletilmesi gereken durumlarda \u00f6nemlidir.<\/p>
#### Debian Tabanl\u0131 Sistemlerde SSL Kurulumu
1. **OpenSSL ve Gerekli K\u00fct\u00fcphanelerin Kurulumu:**
```bash
apt-get -y install openssl
apt-get -y install libssl-dev
```<\/p>
2. **SSL Sertifikalar\u0131n\u0131n Olu\u015fturulmas\u0131:**
```bash
mkdir \/home\/ubuntu\/mysqlcerts
cd \/home\/ubuntu\/mysqlcerts<\/p>
openssl genrsa 2048 > ca-key.pem
openssl req -new -x509 -nodes -days 3600 -key ca-key.pem -out ca.pem<\/p>
openssl req -newkey rsa:2048 -days 3600 -nodes -keyout server-key.pem -out server-req.pem
openssl rsa -in server-key.pem -out server-key.pem
openssl x509 -req -in server-req.pem -days 3600 -CA ca.pem -CAkey ca-key.pem -set_serial 01 -out server-cert.pem<\/p>
openssl req -newkey rsa:2048 -days 3600 -nodes -keyout client-key.pem -out client-req.pem
openssl rsa -in client-key.pem -out client-key.pem
openssl x509 -req -in client-req.pem -days 3600 -CA ca.pem -CAkey ca-key.pem -set_serial 01 -out client-cert.pem
```<\/p>
3. **MySQL Yap\u0131land\u0131rma Dosyas\u0131na SSL Ayarlar\u0131n\u0131n Eklenmesi:**
```bash
vi \/etc\/mysql\/mysql.conf.d\/mysqld.cnf
```
`` b\u00f6l\u00fcm\u00fcne a\u015fa\u011f\u0131daki sat\u0131rlar\u0131 ekleyin:
```ini
ssl-ca = \/home\/ubuntu\/mysqlcerts\/ca.pem
ssl-cert = \/home\/ubuntu\/mysqlcerts\/server-cert.pem
ssl-key = \/home\/ubuntu\/mysqlcerts\/server-key.pem
```<\/p>
4. **MySQL'in Yeniden Ba\u015flat\u0131lmas\u0131:**
```bash
service mysql restart
```<\/p>
5. **SSL Ba\u011flant\u0131s\u0131n\u0131n Test Edilmesi:**
```bash
mysql --ssl-ca=ca.pem --ssl-cert=client-cert.pem --ssl-key=client-key.pem -h 127.0.0.1 -u superman -p
```<\/p>
Ba\u011flant\u0131n\u0131n g\u00fcvenli oldu\u011funu do\u011frulamak i\u00e7in:
```sql
SHOW VARIABLES LIKE '%ssl%';
```<\/p>
#### CentOS\/RHEL 7'de SSL Kurulumu
CentOS\/RHEL 7'de SSL kurulumu benzer ad\u0131mlar\u0131 i\u00e7erir, ancak sertifikalar\u0131n konumu ve dosya yollar\u0131 farkl\u0131 olabilir. \u00d6rne\u011fin, sertifikalar `\/etc\/pki\/tls\/certs\/mysql\/` dizinine yerle\u015ftirilir ve MySQL yap\u0131land\u0131rma dosyas\u0131 (`\/etc\/my.cnf`) g\u00fcncellenir.<\/p>
---<\/p>
### SHOW VARIABLES ve SHOW STATUS Komutlar\u0131<\/p>
MySQL'de sunucu de\u011fi\u015fkenlerini ve durum bilgilerini g\u00f6r\u00fcnt\u00fclemek i\u00e7in `SHOW VARIABLES` ve `SHOW STATUS` komutlar\u0131 kullan\u0131l\u0131r.<\/p>
#### SHOW VARIABLES \u00d6rne\u011fi
Sunucu de\u011fi\u015fkenlerini g\u00f6r\u00fcnt\u00fclemek i\u00e7in:
```sql
SHOW VARIABLES;
```<\/p>
Belirli bir de\u011fi\u015fkeni filtrelemek i\u00e7in:
```sql
SHOW VARIABLES LIKE 'max_join_size';
```<\/p>
Veya joker karakterler kullanarak:
```sql
SHOW VARIABLES LIKE '%size%';
```<\/p>
#### SHOW STATUS \u00d6rne\u011fi
Sunucu durum bilgilerini g\u00f6r\u00fcnt\u00fclemek i\u00e7in:
```sql
SHOW STATUS;
```<\/p>
Belirli bir durum de\u011fi\u015fkenini filtrelemek i\u00e7in:
```sql
SHOW STATUS LIKE 'Threads_connected';
```<\/p>
#### GLOBAL ve SESSION Modifikat\u00f6rleri
- `GLOBAL`: Sunucunun genel de\u011fi\u015fkenlerini ve durum bilgilerini g\u00f6sterir.
- `SESSION`: Mevcut oturum i\u00e7in ge\u00e7erli de\u011fi\u015fkenleri ve durum bilgilerini g\u00f6sterir.<\/p>
\u00d6rnek:
```sql
SHOW GLOBAL VARIABLES;
SHOW SESSION STATUS;
```<\/p>
