feat: refactor 30+ skills to Anthropic progressive disclosure pattern
- All SKILL.md files now <500 lines (avg reduction 69%) - Detailed content extracted to references/ subdirectories - Frontmatter standardised: only name + description (Anthropic standard) - New skills: brand-guidelines, spec-coauthor, report-templates, skill-creator - Design skills: anti-slop guidelines, premium-proposals reference - Removed non-standard frontmatter fields (triggers, version, author, category) Plugins affected: infraestrutura, marketing, dev-tools, crm-ops, gestao, core-tools, negocio, perfex-dev, wordpress, design-media Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# /server-health - Comandos SSH e Template de Output
|
||||
|
||||
## Comandos por Passo
|
||||
|
||||
### Passo 1: Sistema
|
||||
|
||||
```bash
|
||||
uptime
|
||||
free -h
|
||||
df -h
|
||||
top -bn1 | head -20
|
||||
cat /proc/loadavg
|
||||
vmstat 1 3
|
||||
ps aux | grep -E 'httpd|mysql|nginx' | grep -v grep
|
||||
```
|
||||
|
||||
**Validação:**
|
||||
- Load 1min <2: OK | 2-5: Warning | >5: Critical
|
||||
- RAM <70%: OK | Swap >10%: Investigar
|
||||
|
||||
### Passo 2: MySQL
|
||||
|
||||
```bash
|
||||
mysqladmin status
|
||||
mysqladmin processlist | head -20
|
||||
mysql -e "SHOW GLOBAL STATUS LIKE 'Threads%';"
|
||||
mysql -e "SHOW GLOBAL STATUS LIKE 'Slow_queries';"
|
||||
mysql -e "SELECT table_schema, ROUND(SUM(data_length + index_length) / 1024 / 1024, 2) AS 'Size (MB)' FROM information_schema.TABLES GROUP BY table_schema ORDER BY SUM(data_length + index_length) DESC LIMIT 10;"
|
||||
mysqlcheck --all-databases --check
|
||||
```
|
||||
|
||||
**Queries Críticas:**
|
||||
```sql
|
||||
-- Ver queries lentas em execução
|
||||
SELECT id, user, host, db, command, time, state, LEFT(info, 100) as query
|
||||
FROM information_schema.PROCESSLIST
|
||||
WHERE command != 'Sleep' AND time > 5
|
||||
ORDER BY time DESC;
|
||||
|
||||
-- BDs maiores que 500MB
|
||||
SELECT table_schema, ROUND(SUM(data_length + index_length) / 1024 / 1024, 2) AS size_mb
|
||||
FROM information_schema.TABLES
|
||||
GROUP BY table_schema
|
||||
HAVING size_mb > 500
|
||||
ORDER BY size_mb DESC;
|
||||
```
|
||||
|
||||
### Passo 3: Web Servers
|
||||
|
||||
```bash
|
||||
systemctl status httpd --no-pager | head -15
|
||||
systemctl status nginx --no-pager | head -15
|
||||
curl -sI localhost | head -10
|
||||
curl -sI -H 'Accept-Encoding: gzip' localhost | grep -i encoding
|
||||
netstat -an | grep :80 | wc -l
|
||||
netstat -an | grep :443 | wc -l
|
||||
httpd -S 2>&1 | grep -E 'port|namevhost' | head -20
|
||||
```
|
||||
|
||||
### Passo 4: PHP
|
||||
|
||||
```bash
|
||||
php -v | head -1
|
||||
php -i | grep memory_limit
|
||||
php -i | grep -E 'opcache.enable|opcache.memory_consumption'
|
||||
ps aux | grep php-fpm | wc -l
|
||||
```
|
||||
|
||||
### Passo 5: SSL/Certificados
|
||||
|
||||
```bash
|
||||
ls -lh /root/.acme.sh/cwp_certs/
|
||||
|
||||
for d in $(ls /root/.acme.sh/cwp_certs/); do
|
||||
echo "=== $d ==="
|
||||
grep -E 'Le_NextRenewTimeStr|Le_Alt' /root/.acme.sh/cwp_certs/$d/*.conf 2>/dev/null | head -3
|
||||
done
|
||||
|
||||
echo | openssl s_client -connect DOMINIO:443 2>/dev/null | openssl x509 -noout -dates -subject
|
||||
tail -100 /root/.acme.sh/acme.sh.log | grep -E 'Renew|error|success'
|
||||
```
|
||||
|
||||
**Validação SSL:**
|
||||
- Renovação >30 dias: OK | 15-30 dias: Avisar | <15 dias: Urgente
|
||||
|
||||
### Passo 6: Segurança
|
||||
|
||||
```bash
|
||||
systemctl status fail2ban --no-pager 2>/dev/null
|
||||
fail2ban-client status 2>/dev/null | head -10
|
||||
fail2ban-client status sshd 2>/dev/null | grep "Banned IP"
|
||||
netstat -tlnp | grep LISTEN | head -20
|
||||
last -10
|
||||
grep "Failed password" /var/log/secure | tail -20
|
||||
systemctl status firewalld --no-pager || iptables -L -n | head -20
|
||||
```
|
||||
|
||||
### Passo 7: Sites WordPress
|
||||
|
||||
```bash
|
||||
for dir in /home/*/public_html; do
|
||||
if [ -f "$dir/wp-config.php" ]; then
|
||||
domain=$(basename $(dirname $dir))
|
||||
echo "=== $domain ==="
|
||||
grep "wp_version = " $dir/wp-includes/version.php | head -1
|
||||
du -sh $dir/wp-content
|
||||
curl -sI "http://$domain" | head -3
|
||||
fi
|
||||
done
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Verificação Rápida (Quick Mode)
|
||||
|
||||
```bash
|
||||
echo "=== QUICK HEALTH ===" && \
|
||||
uptime && \
|
||||
free -h | grep Mem && \
|
||||
df -h | grep -E '^/dev/vda|Filesystem' && \
|
||||
mysqladmin status 2>&1 | head -1 && \
|
||||
systemctl is-active httpd nginx mysql
|
||||
```
|
||||

|
||||
|
||||
## MySQL Deep Dive
|
||||
|
||||
```bash
|
||||
# Optimizar todas as BDs
|
||||
mysqlcheck --optimize --all-databases
|
||||
|
||||
# Limpar logs binários antigos (>7 dias)
|
||||
mysql -e "PURGE BINARY LOGS BEFORE DATE_SUB(NOW(), INTERVAL 7 DAY);"
|
||||
|
||||
# Verificar fragmentação
|
||||
mysql -e "SELECT table_schema, table_name,
|
||||
ROUND(data_length/1024/1024,2) as data_mb,
|
||||
ROUND(data_free/1024/1024,2) as free_mb
|
||||
FROM information_schema.TABLES
|
||||
WHERE data_free > 0
|
||||
ORDER BY data_free DESC LIMIT 10;"
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Limpeza de Cache/Temp
|
||||
|
||||
```bash
|
||||
# Limpar cache WordPress
|
||||
find /home/*/public_html/wp-content/cache -type f -delete
|
||||
|
||||
# Limpar sessions PHP antigas
|
||||
find /var/lib/php/session -type f -mtime +7 -delete
|
||||
|
||||
# Limpar logs Apache/Nginx >30 dias
|
||||
find /home/*/logs -name "*.log" -mtime +30 -delete
|
||||
```
|
||||

|
||||
|
||||
## Recomendações Prioritárias
|
||||
|
||||
### URGENTE (Hoje)
|
||||

|
||||
2. Renovar SSL solarfv360.pt
|
||||
|
||||
### IMPORTANTE (Esta Semana)
|
||||
3. Optimizar queries lentas MySQL
|
||||
|
||||
### MELHORIAS (Mês)
|
||||
4. Configurar alertas automáticos
|
||||
```

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Swap Alto (>30%)
|
||||
```bash
|
||||
ps aux --sort=-%mem | head -10
|
||||
swapoff -a && swapon -a
|
||||
```
|
||||
|
||||
### Load Alto (>5)
|
||||
```bash
|
||||
ps aux --sort=-%cpu | head -10
|
||||
iostat -x 1 5
|
||||
top -bn1 | head -20
|
||||
```
|
||||
|
||||
### MySQL Lento
|
||||
```bash
|
||||
mysqladmin processlist
|
||||
tail -50 /var/log/mysql/slow.log
|
||||
mysqlcheck --optimize --all-databases
|
||||
```
|
||||
|
||||
### Sites WordPress com Erro
|
||||
```bash
|
||||
tail -100 /home/USER/logs/error.log
|
||||
ls -lh /home/USER/public_html/wp-content
|
||||
chown -R USER:USER /home/USER/public_html/wp-content
|
||||
```
