在 CentOS7.6 安装 MySQL5.7.25

1. 下载 MySQL-5.7.25.tar.gz 添加Mysql用户

[root@node90 ~]# useradd -s /sbin/nologin -c "MySQL" -M mysql

2. 编译安装依赖编译器 安装依赖库

[root@node90 ~]# yum -y install gcc gcc-c++ ncurses ncurses-devel bison bison-devel wget
注意：cmake-3.14.3 需要c++11版本的支持
[root@node90 ~]# wget https://github.com/Kitware/CMake/releases/download/v3.14.3/cmake-3.14.3.tar.gz
[root@node90 cmake-3.14.3]# ./configure
[root@node90 cmake-3.14.3]# make -j `grep processor /proc/cpuinfo | wc -l`
[root@node90 cmake-3.14.3]# make install

3. 安装boost 1.59.0

[root@node90 ~]# wget https://jaist.dl.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz
[root@node90 ~]# tar xzvf boost_1_59_0.tar.gz
[root@node90 ~]# mv boost_1_59_0 /usr/local/
或者使用
#boost根据你使用的mysql的版本改变而改变版本 下载指定版本连接修改连接版本号即可。
[root@node90 ~]# wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.25.tar.gz 

4. 预编译配置项 配置项详细信息

[root@node90 mysql-5.7.25]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DSYSCONFDIR=/usr/local/mysql/etc \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/logs/mysql.sock \
-DMYSQL_TCP_PORT=3306 \
-DWITH_BOOST=/usr/local/boost_1_59_0 \
-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=OFF

5. 编译

[root@node90 mysql-5.7.25]# make -j `grep processor /proc/cpuinfo|wc -l`

6. 安装

[root@node90 mysql-5.7.25]# make install

7. 创建所需要的目录

[root@node90 mysql]# mkdir data logs etc

8. 初始化数据库

修改MySQL目录权限

chown mysql.mysql -R /usr/local/mysql/

将mysql命令添加到环境变量中

[root@node90 mysql]# vi /etc/profile.d/mysql.sh
export MYSQL_HOME=/usr/local/mysql
export PATH=$MYSQL_HOME/bin:$PATH
[root@node90 mysql]# source /etc/profile
[root@node90 mysql]# mysqld --version
mysqld  Ver 5.7.25 for Linux on x86_64 (Source distribution)

初始化MySQL数据库，如果不想生成随机密码使用--initialize-insecure 选项代替 --initalize 选项初始化

[root@node90 mysql]# mysqld --initialize   --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

9. 设置服务器配置文件

[root@node90 mysql]# vi etc/my.cnf

socket = /tmp/mysql.sock
default-character-set = utf8mb4
 
[mysqld]

10. 启动MySQL

[root@node90 mysql]# touch logs/mysql-error.log
[root@node90 mysql]# chown -R mysql.mysql /usr/local/mysql/
[root@node90 mysql]# ./support-files/mysql.server start

11. 登录MySQL 并修改root用户密码

[root@node90 mysql]# mysql -u root -p 
mysql>  ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';
