安装oracle11g时，ORACLE_SID设置成db_254的形式，会导致sqlplus登录时不方便，因此最好设置成exportORACLE_SID=db254的形式，以免引起不必要的麻烦。一小兄弟来

安装oracle11g时，ORACLE_SID设置成db_254的形式，会导致sqlplus登录时不方便，因此最好设置成export ORACLE_SID=db254的形式，以免引起不必要的麻烦。

一小兄弟来电询问，说keepalived做mysql的failover时，，vip可以漂移，但mysql进程自动起不来。疑惑在于：脚本权限没问题，手动运行也是对的。我建议他把配置发过来，其内容为：

global_defs {

router_id LVS_DEVEL

}

vrrp_script check_mysql {

script /tmp/check_mysql.sh

interval 2

weight 2

}

track_script {

check_mysql

}

vrrp_instance VI_1 {

state MASTER

interface eth0

virtual_router_id 51

priority 100

advert_int 1

authentication {

auth_type PASS

auth_pass 1111

}

virtual_ipaddress {

192.168.112.70

}

哈哈，track_script跑到vrrp_instance外边去了，要把它关在里面才行哟！他说网上全是这样，真是以讹传讹，误导人呢!贴个正确的配置在后面，供大家参考：

global_defs {

router_id LVS_DEVEL

}

vrrp_script check_mysql {

script /tmp/check_mysql.sh

interval 2

weight 2

}

vrrp_instance VI_1 {

state MASTER

interface eth0

virtual_router_id 51

priority 100

advert_int 1

authentication {

auth_type PASS

auth_pass 1111

}

track_script {

check_mysql

}

virtual_ipaddress {

192.168.112.70

}

Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
