oracle linux 7.3 下用dtrace 跟踪 mysql-community-server-5.6.20

第一部分：oracle linux 7.3 dtrace 安装:

http://public-yum.oracle.com/

 

内核升极到

[root@server1 SPECS]# uname -r

4.1.12-94.3.8.el7uek.x86_64

 

yum install \

kernel-uek-firmware-4.1.12-94.3.8.el7uek.noarch \

kernel-uek-debug-devel-4.1.12-94.3.8.el7uek.x86_64 \

kernel-uek-doc-4.1.12-94.3.8.el7uek.noarch \

kernel-uek-devel-4.1.12-94.3.8.el7uek.x86_64 \

kernel-uek-4.1.12-94.3.8.el7uek.x86_64 \

 

 

安装DTRACE 程序

yum install

dtrace-utils-devel-0.6.0-3.el7.x86_64      //手动下载

dtrace-utils-0.6.0-3.el7.x86_64            //手动下载

dtrace-modules-4.1.12-94.3.8.el7uek-0.6.0-4.el7.x86_64

 

探针模块加载：

[root@server1 ~]# cat probe.sh

cd /usr/lib/modules/4.1.12-94.3.8.el7uek.x86_64/kernel/drivers/dtrace/

modprobe fbt

modprobe profile

modprobe systrace

modprobe fasttrap

modprobe dtrace

modprobe sdt

 

 

测试：

Testing function entry codes

[root@oel65 Dtrace]# dtrace -n 'syscall::open:entry  { printf("Exec: %s  File: %s" , execname , stringof(arg0) ); }'

dtrace: description 'syscall::open:entry  ' matched 1 probe

CPU     ID                    FUNCTION:NAME

  0      8                       open:entry Exec: udisks-daemon  File: /dev/sr0

  0      8                       open:entry Exec: vminfo  File: /var/run/utmp

  0      8                       open:entry Exec: vminfo  File: /etc/passwd

第二部分MYSQL 安装

1.选择版本：mysql-community-server-5.6.20 起开始内置dtrace(但是mysql 8.0 移除）

2.下载：

http://public-yum.oracle.com/

http://public-yum.oracle.com/repo/OracleLinux/OL7/MySQL56/x86_64/index.html下载四个文件

mysql-community-client-5.6.20-4.el7.x86_64.rpm

mysql-community-common-5.6.20-4.el7.x86_64.rpm

mysql-community-server-5.6.20-4.el7.x86_64.rpm

mysql-community-libs-5.6.20-4.el7.x86_64.rpm

3.安装:

rpm -ivh mysql-community-libs-5.6.20-4.el7.x86_64.rpm

rpm -ivh mysql-community-common-5.6.20-4.el7.x86_64.rpm

rpm -ivh mysql-community-client-5.6.20-4.el7.x86_64.rpm

rpm -ivh mysql-community-server-5.6.20-4.el7.x86_64.rpm

4.文件安装位置
