ununtu15.10源码编译安装mysql5.7.11

本文适合任何linux系统，以Ubuntu15.10为例

官方下载mysql的源码mysql-5.7.11.tar.gz

http://downloads.mysql.com/archives/get/file/mysql-5.7.11.tar.gz

推荐使用下面的链接includes Boost Headers

http://downloads.mysql.com/archives/get/file/mysql-boost-5.7.11.tar.gz

因为如果你使用的上面的链接下过来，编译的时候还是需要在线下载boost

下载之后把源码解压到一个目录，并且准本用于编译，我的位置在/opt/src/mysql-5.7.11

一 编译准备工作

下载编译的linux库和编译工具

Centos系列方法

yum -y install gcc gcc-c++ bison cmake ncurses perlyum -y install make bison-devel ncurses-devel

Ubuntu方法

sudo apt-get install make cmake gcc g++ bison libncurses5-dev

设定一个安装mysql的目录，并创建data和boost目录(注意从现在起使用root权限操作）

sudo mkdir -pv  /usr/local/mysql /usr/local/mysql/data /usr/local/mysql/boost

二 编译三部曲：

（1）cmake一下是必须的cmake设置

sudo cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data  -DWITH_INNOBASE_STORAGE_ENGINE=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock -DMYSQL_TCP_PORT=3306 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/mysql/boost

（2）编译

sudo make

（3）安装

sudo make install

如果make中失败可以使用如下命令

sudo make cleansudo rm -f CMakeCache.txtsudo rm -rf /etc/my.cnf

然后继续make，make过程根据个人电脑配置决定。时间一般要十多分钟，注意查看有没有error等信息

三  安装完成后开始配置 mysql

（1）新建运行Mysql的用户和组

sudo groupadd mysqlsudo useradd -g mysql mysql

（2）设置Mysql安装目录的权限

cd /usr/local/mysqlsudo chown -R mysql:mysql ./

（3）建立配置文件

cp support-files/my-default.cnf /etc/my.cnfsudo chown mysql:mysql /etc/my.cnf

修改配置文件：

sudo vi /etc/my.cnf[client]port = 3306socket = /usr/local/mysql/data/mysql.sock[mysqld]port = 3306socket = /usr/local/mysql/data/mysql.sockbasedir = /usr/local/mysqldatadir  = /usr/local/mysql/data

（4）创建环境变量

vim /etc/profilePATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH

（5）初始化数据库

cd /usr/local/mysql## mysql5.5-5.6sudo scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/## mysql5.7sudo bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

注意mysql5.7初始化与之前有所不同，初始化之前先清空或转移mysql/data下的数据，初始化之后mysql生成一个临时密码，用于第一次登陆

这个密码在初始化日志中。如下

hadoop@hadoop:mysql$ sudo cp support-files/my-default.cnf /etc/my.cnfhadoop@hadoop:mysql$ sudo chown mysql:mysql /etc/my.cnfhadoop@hadoop:mysql$ sudo vi /etc/my.cnfhadoop@hadoop:mysql$ sudo bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data 2016-05-15T11:19:54.773262Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

Table 'mysql.gtid_executed' cannot be opened.2016-05-15T11:19:56.763408Z 1 [Note] A temporary password is generated for root@localhost: oCiiyEkWl1&+

这里生成的临时密码是 oCiiyEkWl1&+在mysql5.7使用一下方法为root用户设置密码

启动mysq,启动方法看下文，执行（这里的password ‘root’是新密码，后面的-p'oCiiyEkWl1&+'是临时密码

bin/mysqladmin -h localhost -u root password 'root' -p'oCiiyEkWl1&+'mysqladmin: [Warning] Using a password on the command line interface can be insecure.Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.##创建新密码成功后，即可使用新密码登陆 root@hadoop:mysql# bin/mysql -uroot -pupdate mysql.user set authentication_string=password('root') where user='root' and Host = 'localhost';

四  mysql启动

方法1：

直接启动

bin/mysqld_safe &

检查MySQL服务是否启动：
ps -ef |grep mysql

hadoop@hadoop:mysql$ sudo bin/mysqld_safe &[1] 14146hadoop@hadoop:mysql$ 2016-05-15T11:26:02.900684Z mysqld_safe Logging to '/usr/local/mysql/data/hadoop.err'.2016-05-15T11:26:02.926254Z mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data2016-05-15T11:26:04.880224Z mysqld_safe mysqld from pid file /usr/local/mysql/data/hadoop.pid endedps -ef |grep mysqlhadoop   14320 25013  0 19:26 pts/20   00:00:00 grep --color=auto mysqlhadoop   24592 23672  0 17:56 ?        00:00:52 gedit /home/hadoop/Desktop/MyDoc/mysqlroot     24679 24555  0 18:00 ?        00:00:00 /bin/sh bin/mysqld_safemysql    24840 24679  0 18:00 ?        00:00:01 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/usr/local/mysql/data/hadoop.err --pid-file=/usr/local/mysql/data/hadoop.pid --socket=/usr/local/mysql/data/mysql.sock --port=3306[1]+  已完成               sudo bin/mysqld_safehadoop@hadoop:mysql$ 

方法2：
通过服务启动
添加服务，复制启动脚本到/etc/init.d目录：

cd /usr/local/mysql/cp support-files/mysql.server /etc/init.d/mysqldsudo chmod 755 /etc/init.d/mysqldsudo /etc/init.d/mysqld startsudo /etc/init.d/mysqld stop## 或者sudo service mysqld startsudo service mysqld stop## 检查MySQL服务是否启动：ps -ef |grep mysqld

（注：）在这里可能有些ubuntu在mysql5.7启动会出现一下错误

Unit mysqld.service failed to load: No such file or directory.

首先确认/etc/init.d/mysqld以及权限没有错误，然后建议安装完mysql重启一下机器，如果还不行，执行如下

systemctl enable mysqld.servicesystemctl start mysqld.service##或<pre name="code" class="plain">systemctl enable mysqldsystemctl start mysqld

再尝试，或者重启后在启动尝试

五 用户和密码

修改root密码

mysql -h127.0.0.1 -uroot -pupdate mysql.user set password=password("mysqldba") where user='root';flush privileges;设置权限：GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;flush privileges;

测试一下：

select now(),user(),version();show databases;

ubuntu设置mysql开机自启动设置和取消

sudo update-rc.d -f mysqld defaultssudo update-rc.d -f mysqld remove
