tokudb_TokuDB 安装
安装TokuDB:
0､关闭内存大页
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
查看下
cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]
cat /sys/kernel/mm/transparent_hugepage/defrag
always madvise [never]
tokuDB内存分配需要jemalloc支持，因此使用之前需要安装jemalloc
yum install -y jemalloc
rpm -qa |grep jemalloc
jemalloc-3.6.0-1.el7.x86_64
rpm -ql jemalloc-3.6.0-1.el7.x86_64
/usr/bin/jemalloc.sh
/usr/lib64/libjemalloc.so.1
/usr/share/doc/jemalloc-3.6.0
/usr/share/doc/jemalloc-3.6.0/COPYING
/usr/share/doc/jemalloc-3.6.0/README
/usr/share/doc/jemalloc-3.6.0/VERSION
/usr/share/doc/jemalloc-3.6.0/jemalloc.html
tar xf Percona-Server-5.7.21-21-Linux.x86_64.ssl101.tar.gz
mv Percona-Server-5.7.21-21-Linux.x86_64.ssl101 tokudb57
mkdir /home/work/data/mysql3504
2､初如化
/home/work/tokudb57/bin/mysqld --defaults-file=/home/work/data/my3504.conf --basedir=/home/work/tokudb57/ --user=work --initialize-insecure
--initialize-insecure 初如化MySQL是空密码
--defaults-file= 指定配置文件,最好放在前面，不要放在最后
3､配置文件my3306.conf
加入：
[mysqld_safe]
thp-setting=never
malloc-lib=/usr/lib64/libjemalloc.so.1
3､启动
chown -R work:work /home/work/data/mysql3306/
改密码:
set password=password('123456');
/home/work/tokudb57/bin/mysqld_safe --defaults-file=/home/work/data/mysql3306/my3306.conf --user=work &
4､安装TokuDB
cd /home/work/tokudb57/bin/
ps_tokudb_admin --enable -u'root' -p -S /home/work/tmp/mysql3306.sock
/home/work/tokudb57/bin/ps_tokudb_admin --enable --user=root --password='' --socket=/home/work/tmp/mysql3306.sock
Enter password:

此时InnoDB还是默认引擎 重启下server，并在my3306.conf [mysqld]添加如下配置:
------------- tokudb ---------------
default-storage-engine = TokuDB
tokudb_directio = on
tokudb_cache_size = 2G
tokudb_row_format = tokudb_lzma
tokudb_commit_sync = 0
tokudb_fsync_log_period = 1000
重启后TokuDB 就是默认存储引擎了

错误:
一、 初始化错误
[ERROR] InnoDB: Expected to open 4 undo tablespaces but was able to find only 0 undo tablespaces.Set the innodb_undo_tablespaces parameter to the correct value and retry. Suggested value is 0
解决：
报错原因：
在初始化数据库的时候没有指定innodb_undo_tablespaces参数
解决方法：
在初始化数据库的时候写上--defaults-file参数，在对应的配置文件中写上对应的innodb_undo_tablespaces参数
/home/work/tokudb57/bin/mysqld --defaults-file=/home/work/data/my3504.conf --basedir=/home/work/tokudb57/ --user=work --initialize-insecure
二、tokudb安装:
root@dqd-stat-mysql-slave01.bj.uc:/home/work/data# ps_tokudb_admin --enable -u'root' -p'123456' -h 127.0.0.1 -P 3504

INFO: SELinux is disabled.
ERROR: Failed to list mysql plugins! Please check username, password and other options for connecting to server...
用户名和密码都是正常的
解决:
/home/work/tokudb57/bin/ps_tokudb_admin --enable --user=root --password='' --socket=/home/work/tmp/mysql3306.sock
三、 Percona Server 未启动
/home/work/tokudb57/bin/ps_tokudb_admin --enable --user=root --password='' --socket=/home/work/tmp/mysql3504.sock

搞了老错误，又来新错误, server是启动的
解决:
root@dqd-stat-mysql-slave01.bj.uc:/home/work/data# grep "Percona Server is not running" /home/work/tokudb57/bin/ps_tokudb_admin
printf "ERROR: Percona Server is not running with jemalloc, please restart mysql service to enable it and then run this script...\n\n";
printf "ERROR: Percona Server is not running with libHotBackup.so preloaded, please restart mysql service to enable it and then run this script again...\n\n";
vim /home/work/tokudb57/bin/ps_tokudb_admin
if [ $ENABLE_TOKUBACKUP = 1 ]; then
printf "Checking if Percona Server is running with libHotBackup.so preloaded...n"
LIBHOTBACKUP_STATUS=$(grep -c libHotBackup.so /proc/${PID_NUM}/environ)
if [ $LIBHOTBACKUP_STATUS = 0 ]; then
printf "ERROR: Percona Server is not running with libHotBackup.so preloaded, please restart mysql service to enable it and then run this script again...\n\n";
exit 1
else
printf "INFO: Percona Server is running with libHotBackup.so preloaded.\n\n";

打开脚本和pid 有关 ，那就回一个pid
root@dqd-stat-mysql-slave01.bj.uc:/home/work/data# grep "pid" /home/work/data/mysql3306/my3306.conf
pid-file = /home/work/tmp/mysql.pid
