1.环境描述
[root@localhost ~]# uname -a
Linux localhost.localdomain 3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22 21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)
2.下载源码包并安装依赖包
链接：https://pan.baidu.com/s/166MCqR2Svd3-30ARS0vg5w
提取码：r3qj
2.1 安装依赖包
yum -y install cmake
yum install gcc gcc-c++ -y
yum -y install ncurses-devel
3.上传源码包Linux服务器并解压预编译
3.1 上传解压
# 上传源码包到Linux服务器
rz命令
# 解压
tar -zxvf mysql-5.7.21.tar.gz
tar -zxvf boost_1_59_0.tar.gz
# 将boost解压后的文件移动到/usr/local/boost
mv boost_1_59_0 /usr/local/boost
# 进入到目录
cd mysql-5.7.21
3.2 预编译
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql5/
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock
-DMYSQL_DATADIR=/data/mysql/
-DSYSCONFDIR=/etc
-DMYSQL_USER=mysql
-DMYSQL_TCP_PORT=3306
-DWITH_XTRADB_STORAGE_ENGINE=1
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DWITH_PARTITION_STORAGE_ENGINE=1
-DWITH_BLACKHOLE_STORAGE_ENGINE=1
-DWITH_MYISAM_STORAGE_ENGINE=1
-DWITH_READLINE=1
-DENABLED_LOCAL_INFILE=1
-DWITH_EXTRA_CHARSETS=1
-DDEFAULT_CHARSET=utf8
-DDEFAULT_COLLATION=utf8_general_ci
-DEXTRA_CHARSETS=all
-DWITH_BIG_TABLES=1
-DWITH_DEBUG=0
-DWITH_BOOST=/usr/local/boost
出现下图表示cmake成功
3.3 make && make install
# -j4表示同时开启4个进程
make -j4 && make install -j4
在编译安装的过程中可能出现如下错误：
出现上述错误后，继续使用命令编译即可：
make && make install
4.进行启动和初始化
# 进入安装目录
[root@localhost mysql-5.7.21]# cd /usr/local/mysql5/
[root@localhost mysql5]# pwd
/usr/local/mysql5
[root@localhost mysql5]# ll

mysql 5.7版本的配置文件和执行启动文件需要自己写或者拷贝
Centos 系统默认有/etc/my.cnf文件，需要替换或者删除文件，重新写入mysql 5.7版本的配置文件
mysql 5.7 版本默认密码是在第一次启动之后会在日志中生成，可以直接搜索password字段，第一次登录修改密码，就需要使用默认密码，然后再去修改
# 配置用户和安装目录
groupadd mysql
useradd -g mysql -r mysql
cd /usr/local/mysql5 && chown mysql:mysql -R .
mkdir -p /data/mysql && chown mysql:mysql -R /data/mysql
# 配置完成之后，修改/etc/my.cnf文件
[root@localhost mysql5]# vim /etc/my.cnf
[mysqld]
basedir = /usr/local/mysql5
datadir = /data/mysql
port = 3306
socket = /tmp/mysql.sock
如下图：
配置完成之后，初始化数据库
[root@localhost etc]# /usr/local/mysql5/bin/mysqld --initialize --user=mysql --datadir=/data/mysql --basedir=/usr/local/mysql5

2019-08-21T10:21:39.343579Z 0 [Warning] InnoDB: New log files created, LSN=45790
2019-08-21T10:21:39.648591Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
2019-08-21T10:21:39.718993Z 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: 76b46fdb-c3fd-11e9-b098-000c2916d1d0.

2019-08-21T10:21:39.726003Z 1 [Note] A temporary password is generated for root@localhost: VI:N(rjb0M;H
从上述返回结果我们可以知道初始密码为：VI:N(rjb0M;H
5.配置命令连接和脚本启动
ln -s /usr/local/mysql5/bin/* /usr/bin/
cp support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig --level 35 mysqld on
# 启动数据库
service mysqld restart
出现上图表示服务已经启动成功
查看mysql进程
6.使用默认密码连接数据库
[root@localhost bin]# cd /usr/local/mysql5/bin/ && ./mysql -uroot -p'VI:N(rjb0M;H'
mysql: [Warning] Using a password on the command line interface can be insecure.
