MySQL 5.7主要特性

1、更好的性能

对于多核CPU、固态硬盘、锁有着更好的优化,每秒100W QPS已不再是MySQL的追求,下个版本能否上200W QPS才是用户更关心的。

2、更好的InnoDB存储引擎

3、更为健壮的复制功能

复制带来了数据完全不丢失的方案,传统金融客户也可以选择使用。此外,GTID在线平滑升级也变得可能。

4、更好的优化器

优化器代码重构的意义将在这个版本及以后的版本中带来巨大的改进,Oracle官方正在解决MySQL之前最大的难题。

5、原生JSON类型的支持

6、更好的地理信息服务支持

InnoDB原生支持地理位置类型,支持GeoJSON,GeoHash特性
7、新增sys库

以后这会是DBA访问最频繁的库MySQL 5.7已经作为数据库可选项添加到《OneinStack》

安装准备

安装依赖包

[root@snails ~]# yum -y install gcc gcc-c++ ncurses ncurses-devel cmake bison

下载相应源码包

[root@snails ~]# wget https://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
[root@snails ~]# wget http://cdn.mysql.com/Downloads/MySQL-5.7/mysql-5.7.13.tar.gz

新建MySQL用户和用户组

[root@snails ~]# groupadd -r mysql && useradd -r -g mysql -s /sbin/nologin -M mysql

预编译

[root@snails ~]# tar -zxvf boost_1_59_0.tar.gz
[root@snails data]# md5sum mysql-5.7.13.tar.gz 
8fab75dbcafcd1374d07796bff88ae00 mysql-5.7.13.tar.gz
[root@snails ~]# tar -zxvf mysql-5.7.13.tar.gz
[root@snails data]# mkdir -p /data/mysql
[root@snails data]# cd mysql-5.7.13
[root@snails data]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DWITH_BOOST=../boost_1_59_0 -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1 -DENABLE_DTRACE=0 -DDEFAULT_CHARSET=utf8mb4 -DDEFAULT_COLLATION=utf8mb4_general_ci -DWITH_EMBEDDED_SERVER=1

编译安装

[root@snails mysql-5.7.13]# make -j `grep processor /proc/cpuinfo | wc -l`
#编译很消耗系统资源,小内存可能编译通不过make install
[root@snails mysql-5.7.13]# make install

设置启动脚本,开机自启动

[root@snails mysql-5.7.13]# ls -lrt /usr/local/mysql
[root@snails mysql-5.7.13]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@snails mysql-5.7.13]# chmod +x /etc/init.d/mysqld
[root@snails mysql-5.7.13]# systemctl enable mysqld
mysqld.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig mysqld on

添加mysql的环境变量

复制代码 代码如下:
[root@snails mysql-5.7.13]# echo -e '\n\nexport PATH=/usr/local/mysql/bin:$PATH\n' /etc/profile && source /etc/profile

初始化数据库

复制代码 代码如下:
[root@snails mysql-5.7.13]# mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

注:

  • MySQL之前版本mysql_install_db是在mysql_basedir/script下
  • MySQL 5.7直接放在了mysql_install_db/bin目录下。
  • "–initialize"已废弃,生成一个随机密码(~/.mysql_secret)
  • "–initialize-insecure"不会生成密码
  • "–datadir"目录下不能有数据文件

启动数据库

[root@snails mysql-5.7.13]# systemctl start mysqld
[root@snails mysql-5.7.13]# systemctl status mysqld
 mysqld.service - LSB: start and stop MySQL
 Loaded: loaded (/etc/rc.d/init.d/mysqld)

查看MySQL服务进程和端口

[root@snails mysql-5.7.13]# ps -ef | grep mysql
root  23940  1 0 11:15 "htmlcode">
[root@snails mysql-5.7.13]# mysql_secure_installation

常用操作

将MySQL数据库的动态链接库共享至系统链接库

一般MySQL数据库还会被类似于PHP等服务调用,所以我们需要将MySQL编译后的lib库文件添加至当前Linux主机链接库 /etc/ld.so.conf.d/下,这样MySQL服务就可以被其它服务调用了。

 [root@snails mysql-5.7.13]# ldconfig |grep mysql
[root@snails mysql-5.7.13]# echo "/usr/local/mysql/lib" > /etc/ld.so.conf.d/mysql.conf
[root@snails mysql-5.7.13]# ldconfig
[root@snails mysql-5.7.13]# ldconfig -v |grep mysql
ldconfig: 无法对 /libx32 进行 stat 操作: 没有那个文件或目录
ldconfig: 多次给出路径“/usr/lib”
ldconfig: 多次给出路径“/usr/lib64”
ldconfig: 无法对 /usr/libx32 进行 stat 操作: 没有那个文件或目录
/usr/lib64/mysql:
 libmysqlclient.so.18 -> libmysqlclient.so.18.0.0
/usr/local/mysql/lib:
 libmysqlclient.so.20 -> libmysqlclient.so.20.3.0

创建其它MySQL数据库用户

[root@snails mysql-5.7.13]# mysql -uroot -p

《魔兽世界》大逃杀!60人新游玩模式《强袭风暴》3月21日上线

暴雪近日发布了《魔兽世界》10.2.6 更新内容,新游玩模式《强袭风暴》即将于3月21 日在亚服上线,届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。

艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕,并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时,他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中,玩家将会进入一个全新的海盗主题大逃杀式限时活动,其中包含极高的风险和史诗级的奖励。

《强袭风暴》不是普通的战场,作为一个独立于主游戏之外的活动,玩家可以用大逃杀的风格来体验《魔兽世界》,不分职业、不分装备(除了你在赛局中捡到的),光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式,玩家在加入海盗主题的预赛大厅区域前,可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹,《巨龙崛起》和《魔兽世界:巫妖王之怒 经典版》的玩家都可以获得奖励。
