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。

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

也可以使用官方下载链接 进行下载。

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 \

-DENABLE_DTRACE=0 \

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

[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

[root@snails mysql-5.7.13]# mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

注:

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 ?        00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/data/mysql --pid-file=/data/mysql/mysql.pid

[root@snails mysql-5.7.13]# netstat -tunpl | grep 3306
tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      24776/mysqld

设置数据库 root 用户密码

MySQL 和 Oracle 数据库一样,数据库也默认自带了一个 root 用户(这个和当前 Linux 主机上的 root 用户是完全不搭边的),我们在设置好 MySQL 数据库的安全配置后初始化 root 用户的密码。配制过程中,一路输入 y 就行了。这里只说明下 MySQL5.7.13 版本中,用户密码策略分成低级 LOW 、中等 MEDIUM 和超强 STRONG 三种,推荐使用中等 MEDIUM 级别!

[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
Enter password:
