mysql5.7编译安装

1.      安装库文件

安装编译代码需要的包

shell>yum -y install make gcc-c++ bisonncurses-devel #Set timezone(设置服务器的时区：亚洲上海) shell>rm -rf /etc/localtime shell>ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime          #Remove MYSQL if exists mysql (删除服务器上已存在MYSQL,切记数据库备份)      shell>rpm -qa|grep mysql shell>rpm -e mysql shell>yum -y remove mysql-server mysql mysql-libs

 

2.      下载编译安装cmake

cmake-2.8.4.tar.gz,cmake安装包.在www.cmake.org可下最新版本

Shell>tar  -zxvf cmake-2.8.8.tar.gz shell>cd cmake-2.8.8 shell>./bootstrap shell>make shell>make install

 

3.      下载安装boost

(MySQL currently requires boost_1_59_0)，http://sourceforge.net/projects/boost/files/boost/

shell>unzipboost_1_59_0.zip shell>mvboost_1_59_0  /usr/local/boost shell>cd  /usr/local/boost shell> ./bootstrap.sh shell> ./b2

 

4.      编译安装Mysql 5.7.9版本

shell>tar zxvf mysql-5.7.9.tar.gz shell>cd mysql-5.7.9 shell>cmake  -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_DATADIR=/usr/local/mysql/data \ -DSYSCONFDIR=/etc \ -DWITH_MYISAM_STORAGE_ENGINE=1  \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_ARCHIVE_STORAGE_ENGINE=1   \ -DWITH_BLACKHOLE_STORAGE_ENGINE=1  \ -DWITH_PERFSCHEMA_STORAGE_ENGINE=1  \ -DWITH_PARTITION_STORAGE_ENGINE=1  \ -DWITH_EXAMPLE_STORAGE_ENGINE=0    \ -DWITH_FEDERATED_STORAGE_ENGINE=0  \ -DWITH_BOOST=/usr/local/boost    \ -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \ -DMYSQL_TCP_PORT=3306 \ -DENABLED_LOCAL_INFILE=1 \ -DENABLED_PROFILING=1    \ -DWITH_EXTRA_CHARSETS=gbk,gb2312,utf8,ascii,utf8mb4 \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci   shell>make -j`grep processor /proc/cpuinfo | wc -l` && make install

 

5.      配置MySQL用户

shell>groupadd mysql shell>useradd -g mysql  -s /sbin/nologin mysql

修改权限

shell>chown -R mysql.mysql /usr/local/mysql shell>mkdir /var/lib/mysql shell>chown -R mysql.mysql /var/lib/mysql        #socket文件存放位置

 

6.      初始化mysql数据库

进入安装路径，执行初始化配置脚本，创建系统自带的数据库和表

shell> bin/mysql_install_db --user=mysql # Before MySQL 5.7.6 shell> bin/mysqld --initialize --user=mysql--basedir=/usr/local/mysql--datadir=/usr/local/mysql/data # MySQL 5.7.6 and up   2015-10-25T13:55:17.985338Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2015-10-25T13:55:20.481855Z 0 [Warning] InnoDB: New log files created, LSN=45790 2015-10-25T13:55:20.757621Z 0 [Warning] InnoDB: Creating foreign key constraint system tables. 2015-10-25T13:55:20.829606Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 0803aa28-7b20-11e5-9937-000c29502ea3. 2015-10-25T13:55:20.831561Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened. 2015-10-25T13:55:20.844288Z 1 [Note] A temporary password is generated forroot@localhost: 8QVlQ(s82//L

 

7.      修改my.cnf配置文件(自由发挥)

shell>vi /etc/my.cnf [mysqld] # These are commonly set, remove the # and set as required. basedir=/usr/local/mysql datadir=/usr/local/mysql/data port=3306 #server_id = ..... socket=/var/lib/mysql/mysql.sock

 

8.      添加mysql自启动
添加服务，拷贝服务脚本到init.d目录，并设置开机启动

shell>cp support-files/mysql.server /etc/init.d/mysqld shell>chkconfig mysqld on shell>service mysqld start

 

9.      配置环境变量

MySQL启动成功后，root默认没有密码，我们需要设置root密码。

设置之前，我们需要先设置PATH，使之直接调用mysql

修改/etc/profile文件，在文件末尾添加

#vi /etc/profile PATH=/usr/local/mysql/bin:$PATH export PATH

关闭文件，运行下面的命令，让配置立即生效

#source /etc/profile

 

10.  新添加的初始化密码

mysql5.7会生成一个初始化密码

shell>mysql -uroot  -p’eZ4hXJ,r2Tde’ mysql> show databases; ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement. 修改默认密码 mysql>alter user 'root'@'localhost' identified by '123456';

 

11.  添加防火墙

防火墙的3306端口默认没有开启，若要远程访问，需要开启这个端口

打开/etc/sysconfig/iptables

在“-A INPUT –m state--state NEW –m tcp –p –dport 22 –j ACCEPT”，下添加：

-A INPUT-m state --state NEW -m tcp -p -dport 3306 -j ACCEPT

然后保存，并关闭该文件，在终端内运行下面的命令，刷新防火墙配置：

serviceiptables restartCentOS 7中默认使用Firewalld做防火墙，所以修改iptables后，在重启系统后，根本不管用。

Firewalld中添加端口方法如下：

firewall-cmd--zone=public --add-port=3306/tcp --permanent

firewall-cmd--reload
