}
PostgreSQL 主从复制:
# 1. 主节点配置(10.0.2.10)
vi /etc/postgresql/15/main/postgresql.conf
# 添加配置:
listen_addresses = '10.0.2.10'
wal_level = replica
max_wal_senders = 3
wal_keep_size = 1GB
# 2. 创建复制用户
sudo -u postgres psql
CREATE USER replica_user WITH REPLICATION ENCRYPTED PASSWORD 'your_password';
# 3. 编辑 pg_hba.conf
vi /etc/postgresql/15/main/pg_hba.conf
# 添加:
host replication replica_user 10.0.2.11/32 scram-sha-256
# 4. 从节点配置(10.0.2.11)
# 停止 PostgreSQL
sudo systemctl stop postgresql
# 清空数据目录
sudo rm -rf /var/lib/postgresql/15/main/*
# 执行基础备份
sudo -u postgres pg_basebackup -h 10.0.2.10 -D /var/lib/postgresql/15/main -U replica_user -P -v -R
# 启动 PostgreSQL
sudo systemctl start postgresql
# 5. 验证复制状态
sudo -u postgres psql -c "SELECT * FROM pg_stat_replication;"
# 1. 安装 Redis Cluster
sudo dnf install redis -y
# 2. 配置 Redis 集群(节点 1:10.0.3.10)
vi /etc/redis/redis.conf
# 修改配置:
bind 10.0.3.10
port 6379
cluster-enabled yes
cluster-config-file nodes-6379.conf
cluster-node-timeout 5000
appendonly yes
# 3. 配置 Redis 集群(节点 2:10.0.3.11)
vi /etc/redis/redis.conf
# 修改配置:
bind 10.0.3.11
port 6379
cluster-enabled yes
cluster-config-file nodes-6379.conf
cluster-node-timeout 5000
appendonly yes
# 4. 启动 Redis 集群
sudo systemctl start redis
# 5. 创建集群
redis-cli --cluster create 10.0.3.10:6379 10.0.3.11:6379 --cluster-replicas 1
# 6. 验证集群状态
redis-cli -c cluster info
