#查看系统版本
[root@ctos3 ~]# cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core)
#下载源码包，需要注意的是mysql5.7 编译安装需要boost 库，可以在官网下载含boost的源码包
https:/https://img.qb5200.com/download-x/dev.mysql.comhttps://img.qb5200.com/download-x/downloads/mysql/5.7.html#downloads
#提示，下载的时候如果不想进行登录或注册，就点不用，开始下载
#开始源码编译安装
#1.安装相关依赖包
yum install -y gcc gcc-c++ cmake ncurses ncurses-devel bison wget openssl-devel.x86_64
#2.创建用户和组
groupadd mysql useradd mysql -s /sbin/nologin -M -g mysql
#3.下载mysql和解压,也可以下载好使用rz(包名lrzsz)上传
mkdir /homehttps://img.qb5200.com/download-x/demo/tools/ cd /homehttps://img.qb5200.com/download-x/demo/tools/
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.29.tar.gz
tar xf mysql-boost-5.7.29.tar.gz
#4.配置相关参数
[root@ctos3 tools]# cd mysql-5.7.29/ [root@ctos3 mysql-5.7.29]# pwd /homehttps://img.qb5200.com/download-x/demo/tools/mysql-5.7.29 [root@ctos3 mysql-5.7.29]# cmake -DCMAKE_INSTALL_PREFIX=/application/mysql -DMYSQL_DATADIR=/application/mysqlhttps://img.qb5200.com/download-x/data -DMYSQL_UNIX_ADDR=/application/mysql/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_BOOST=boost
#参数介绍
DCMAKE_INSTALL_PREFIX #指定MySQL程序的安装目录 DMYSQL_DATADIR #数据文件目录 DMYSQL_UNIX_ADDR #socket文件路径 DDEFAULT_CHARSET #指定服务器默认字符集，默认latin1 DDEFAULT_COLLATION #指定服务器默认的校对规则，默认latin1_general_ci
#5.编译安装
[root@ctos3 mysql-5.7.29]# make -j 2 && make install
#-j参数作用：编译时会占用大量的系统资源，可以通过-j参数指定多个编译命令进行并行编译来提高速度,使用以下命令查看系统CPU核数
[root@ctos3 ~]# cat /proc/cpuinfo | grep processor |wc -l 2
#6.创建数据目录和修改权限
[root@ctos3 mysql-5.7.29]# mkdir /application/mysqlhttps://img.qb5200.com/download-x/data #存放数据目录
[root@ctos3 mysql-5.7.29]# mkdir /application/mysql/tmp #存放sock目录
[root@ctos3 mysql-5.7.29]# chown -R mysql.mysql /application/mysql/
#7.配置/etc/my.cnf文件
#注意：5.7版本没有模板文件/application/mysql/support-files/my-default.cnf，可根据需要自行添加
[root@ctos3 ~]# cat /etc/my.cnf [mysqld] port = 3306 socket = /application/mysql/tmp/mysql.sock user = mysql basedir = /application/mysql datadir = /application/mysqlhttps://img.qb5200.com/download-x/data pid-file = /application/mysqlhttps://img.qb5200.com/download-x/data/mysql.pid sql_mode='ONLY_FULL_GROUP_BY' log_error = /application/mysql/mysql-error.log !includedir /etc/my.cnf.d [client] port = 3306 socket = /application/mysql/tmp/mysql.sock
#8.初始化数据库
[root@ctos3 support-files]# /application/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/application/mysql --datadir=/application/mysqlhttps://img.qb5200.com/download-x/data
#9.生成服务启动脚本
#设置环境变量 [root@ctos3 support-files]# echo 'export PATH=/application/mysql/bin:$PATH' >> /etc/profile [root@ctos3 support-files]# source /etc/profile [root@ctos3 support-files]# tail -1 /etc/profile export PATH=/application/mysql/bin:$PATH #生成启动脚本 [root@ctos3 ~]# cd /application/mysql/support-files/ [root@ctos3 support-files]# ls magic mysqld_multi.server mysql-log-rotate mysql.server [root@ctos3 support-files]# cp mysql.server /etc/init.d/mysqld #启动服务和设置开机自启 [root@ctos3 support-files]# /etc/init.d/mysqld start Starting MySQL. SUCCESS! [root@ctos3 support-files]# chkconfig mysqld on
#10.登录MySQL(没有密码登录)
[root@ctos3 ~]# mysql -uroot -p Enter password:
#11.查看版本
mysql> select version(); +-----------+ | version() | +-----------+ | 5.7.29 | +-----------+ 1 row in set (0.00 sec)
#12.设置密码
mysql> update mysql.user set authentication_string=password('guoke123') where user='root';
Query OK, 1 row affected, 1 warning (0.01 sec)
Rows matched: 1 Changed: 1 Warnings: 1
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
