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;

9.修改系统文件描述符的数量

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
