安装TokuDB 1, 创建mysql数据目录 #顺便把临时目录创建好
mkdir -p /data/mysql/tmp
groupadd -r mysql
useradd -g mysql -r -s /sbin/nologin -M -d /data/mysql mysql
chown -R mysql:mysql /data/mysql 2, 编辑配置文件vim /etc/my.cnf
[mysqld]
datadir=/data/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
bind-address=xx(替换为内网IP地址)
#unique_checks=OFF
#tokudb_commit_sync=OFF
#tokudb_fsync_log_period=1000
max_connections=1000
#default-storage-engine=TokuDB #先把这一条配置注释掉，因为这时候还没安装TokuDB，不注释的话mysql会启动失败，等安装完TokuDB引擎后再打开这行配置
tmpdir=/data/mysql/tmp/ #修改临时数据存放目录（默认是tmp下面，如果查日志时临时数据比较大的话会差不到，会报警磁盘不够。） [mysqld_safe]
thp-setting=never
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid 3, 安装
yum install http://www.percona.com/downloads/percona-release/redhat/0.1-3/percona-release-0.1-3.noarch.rpm
yum install Percona-Server-tokudb-56.x86_64 4, 启动 # (如需安装多实例)初始化数据库实例并启动数据库
# /usr/bin/mysql_install_db --user=mysql --datadir=/data/mysql_toku_3307 --basedir=/usr/ --defaults-file=/data/mysql_toku_3307/my.cnf &
# /usr/bin/mysqld_safe --defaults-file=/data/mysql_toku_3307/my.cnf --user=mysql &
# mysql_install_db 4.1初始化数据库：
/usr/bin/mysql_install_db --user=mysql --datadir=/data/mysql --basedir=/usr/ service mysql start 5, 增加用户
echo "insert into mysql.user (Host,User,Password,ssl_cipher,x509_issuer,x509_subject) values('%','xx',password('xx'),'','','');grant all privileges on *.* to 'xx'@'%' identified by 'xx';flush privileges; " | mysql -uroot 6, 安装TokuDB引擎
ps_tokudb_admin --enable -uxx -pxx -h内网IP地址 7, 设置TokuDB为默认引擎
SET global default_storage_engine=TokuDB; (需要重新登录mysql才能看到生效) 8, 查看是否安装成功 show engines; 查看版本 SELECT @@tokudb_version; mysql> show engines;

vim /etc/security/limits.conf * soft nproc 655300
* hard nproc 655300
* soft nofile 655300
* hard nofile 655300 10.把/etc/my.cnf 里面的#default-storage-engine=TokuDB 注释打开并重启mysql
/etc/init.d/mysql restart
