进入MySQL官网下载页面,地址https://www.mysql.com/downloads/,如果你想使用MySQL 5.7.19的源码版本,点此处直接下载!
选择操作系统为Source Code,选择操作系统版本为Generic Linux,选择Compressed TAR Archive, Includes Boost Headers版本或Compressed TAR Archive版本,暂未研究两个版本的区别,开始以为Includes Boost Headers不用再去下载Boost库,然而安装时发现还是需要,所以此处先任意选择一个版本,选择点击 Download 进行下载
进入/usr/local/src目录,一般我喜欢把下载的文件放在此目录,根据自己的喜好设定
[root@iZ2864f6btwZ src]# cd /usr/local/src
下载MySQL文件,如果wget没有安装,yum -y install wget即可安装
[root@iZ2864f6btwZ src]# wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-boost-5.7.19.tar.gz
问题错误:
如果此处下载遇到如下问题,说明你没有安装openssl,此问题一般只会出现在全新的机器上
[root@iZ2864f6btwZ src]# wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-boost-5.7.19.tar.gz--2017-09-22 16:20:26-- https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-boost-5.7.19.tar.gz Resolving dev.mysql.com (dev.mysql.com)... 137.254.60.11 Connecting to dev.mysql.com (dev.mysql.com)|137.254.60.11|:443... connected. Unable to establish SSL connection.
解决方案:
安装opensll,yum -y install openssl 再次执行下载命令即可
由于MySQL 5.7需要boost 1.59以及以上版本,所以还需要下载boost库,根据本人测试1.59版本的最为适合,其它高版本在安装的时候遇到了一些问题,目前未解决;下载地址,你也可以点击此处直接下载boost_1_59_0.tar.gz,如果wget无法下载,建议使用迅雷下载后再上传到服务器目录
[root@iZ2864f6btwZ src]# wget http://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
解压 boost并拷贝 boost 到 /usr/local/boost 目录
[root@iZ2864f6btwZ src]# tar zxvf boost_1_59_0.tar.gz
[root@iZ2864f6btwZ src]# cp -r boost_1_59_0 /usr/local/boost
安装编译所需的常用组件和依赖包 [ 参考于网络博客 ]
[root@iZ2864f6btwZ src]# yum -y install gcc gcc-c++ ncurses ncurses-devel bison libgcrypt perl make cmake
创建mysql用户组和用户,用来运行mysql服务器, -g指定用户组, -r创建系统用户
[root@iZ2864f6btwZ src]# groupadd mysql
[root@iZ2864f6btwZ src]# useradd -r -g mysql -s /bin/false -M mysql
解压MySQL,进入 mysql-5.7.19 目录
[root@iZ2864f6btwZ src]# tar zxvf mysql-boost-5.7.19.tar.gz
[root@iZ2864f6btwZ src]# cd mysql-5.7.19/
新建MySQL安装所需要目录
[root@iZ2864f6btwZ mysql-5.7.19]# mkdir -p /usr/local/mysql /usr/local/mysql/{data,logs,pids}
修改 /usr/local/mysql 目录所有者权限
[root@iZ2864f6btwZ mysql-5.7.19]# chown -R mysql:mysql /usr/local/mysql
使用cmake命令进行编译
[root@iZ2864f6btwZ mysql-5.7.19]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DMYSQL_TCP_PORT=3306 -DMYSQL_USER=mysql -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DENABLE_DOWNLOADS=1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost
使用make命令进行编译,接下来你将经历漫长的等待~
[root@iZ2864f6btwZ mysql-5.7.19]# make
问题错误:
编译出现错误,查询得知可能是由于内存不足导致的
解决方案:
临时增加交换空间 ( 虚拟内存 )
[root@iZ2864f6btwZ mysql-5.7.19]# dd if=/dev/zero of=/swapfile bs=1k count=2048000
2048000+0 records in
2048000+0 records out
2097152000 bytes (2.1 GB) copied, 34.6782 s, 60.5 MB/s
[root@iZ2864f6btwZ mysql-5.7.19]# mkswap /swapfile
Setting up swapspace version 1, size = 2047996 KiB
no label, UUID=56026239-26e6-40d9-b080-b95acd9db058
[root@iZ2864f6btwZ mysql-5.7.19]# swapon /swapfile
swapon: /swapfile: insecure permissions 0644, 0600 suggested.
[root@iZ2864f6btwZ mysql-5.7.19]# chmod 600 /swapfile
查看创建的交换空间
[root@iZ2864f6btwZ mysql-5.7.19]# free -m
total used free shared buff/cache available
Mem: 992 51 70 0 869 789
Swap: 1999 0 1999
继续执行make命令
[root@iZ2864f6btwZ mysql-5.7.19]# make clean
[root@iZ2864f6btwZ mysql-5.7.19]# make
如果你编译完成后不再想要此交换空间,你可以执行如下命令:
[root@iZ2864f6btwZ mysql-5.7.19]# swapoff /swapfile
[root@iZ2864f6btwZ mysql-5.7.19]# rm /swapfile
温馨提示:
MySQL编译过程等待时间会比较久,有时都以为是“卡”住了,你可以使用top命令查看资源状态,看看cc1plus、make等进程是否在跳动,如果有跳动说明安装还在继续,由于我的 ecs 配置较低,此过程大约经历了几个小时,特别是在29%和74%的时候,几乎都要快放弃了, 如果有经济的能力的话,建议服务器配置还是尽量买高一点。
[root@iZ2864f6btwZ mysql-5.7.19]# top
编译完成后执行 make install 进行安装
[root@iZ2864f6btwZ mysql-5.7.19]# make install
将mysql添加到环境变量,修改/etc/profile文件,在文件最末尾添加export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
[root@iZ2864f6btwZ mysql-5.7.19]# vim /etc/profile
...
unset i
unset -f pathmunge
# mysql执行路径
export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
更新配置文件
[root@iZ2864f6btwZ mysql-5.7.19]# source /etc/profile
初始化数据库, –initialize 表示默认生成一个安全的密码,–initialize-insecure 表示不生成密码
[root@iZ2864f6btwZ mysql-5.7.19]# mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
将mysql服务文件拷贝到/etc/init.d/目录,并给出执行权限
[root@iZ2864f6btwZ mysql-5.7.19]# cp support-files/mysql.server /etc/init.d/mysqld
[root@iZ2864f6btwZ mysql-5.7.19]# chmod a+x /etc/init.d/mysqld
将MySQL并加入开机自动启动
[root@iZ2864f6btwZ mysql-5.7.19]# chkconfig --add mysqld
[root@iZ2864f6btwZ mysql-5.7.19]# chkconfig mysqld on
[root@iZ2864f6btwZ mysql-5.7.19]# chkconfig --list | grep mysqld
Note: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.
If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use
'systemctl list-dependencies [target]'.
mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
修改/etc/my.cnf文件,编辑配置文件如下,仅供参考
[root@iZ2864f6btwZ mysql-5.7.19]# vim /etc/my.cnf
[mysqld]
datadir=/usr/local/mysql/data
socket=/usr/local/mysql/mysql.sock
[mysqld_safe]
log-error=/usr/local/mysql/logs/mysqld.log
pid-file=/usr/local/mysql/pids/mysqld.pid
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd

启动MySQL
[root@iZ2864f6btwZ local]# service mysqld start
Starting MySQL.2017-09-23T16:13:16.049373Z mysqld_safe error: log-error set to '/usr/local/mysql/logs/mysqld.log', however file don't exists. Create writable for user 'mysql'.
The server quit without updating PID file (/usr/local/mysql[FAILED]2864f6btwZ.pid).
问题错误:
由于缺少 mysqld.log 和 mysqld.pid 文件导致无法正常启动
解决方案:
创建 mysqld.log 和 mysqld.pid 文件
[root@iZ2864f6btwZ mysql-5.7.19]# touch /usr/local/mysql/logs/mysqld.log
[root@iZ2864f6btwZ mysql-5.7.19]# touch /usr/local/mysql/pids/mysqld.pid
修改 /usr/local/mysql 的权限
[root@iZ2864f6btwZ mysql-5.7.19]# chown mysql.mysql -R /usr/local/mysql/
再次启动MySQL
[root@iZ2864f6btwZ local]# service mysqld start
查看MySQL运行状态
[root@iZ2864f6btwZ local]# service mysqld status
MySQL is not running, but lock file (/var/lock/subsys/mysql[FAILED]
问题错误:
MySQL is not running, but lock file (/var/lock/subsys/mysql[FAILED]
解决方案:
删除/var/lock/subsys/mysql文件,重新启动MySQL
[root@iZ2864f6btwZ local]# rm -f /var/lock/subsys/mysql
[root@iZ2864f6btwZ local]# service mysqld start

[root@iZ2864f6btwZ mysql-5.7.19]#
问题错误:
/etc/my.cnf 文件配置不正确
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
解决方案:
参考上述步骤 修改 /etc/my.cnf 文件
[root@iZ2864f6btwZ local]# mysql -u root

mysql>
问题错误:
ERROR 1054 (42S22): Unknown column 'password' in 'field list'
解决方案:
由于MySQL 5.7版本下的mysql数据库下已经没有password这个字段了,password字段改成了authentication_string,查询时使用authentication_string字段即可
mysql> select host,user,authentication_string from user;
+-----------+---------------+-------------------------------------------+
| host | user | authentication_string |
+-----------+---------------+-------------------------------------------+
| localhost | root | |
| localhost | mysql.session | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE |
| localhost | mysql.sys | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE |
+-----------+---------------+-------------------------------------------+
3 rows in set (0.00 sec)
设置密码(推荐),注意此方法必须使用flush privileges命令刷新一下权限才能生效
mysql> UPDATE user SET authentication_string=PASSWORD('newpassword') WHERE user='root';
Query OK, 1 row affected, 1 warning (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 1
mysql>
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql>
另外一种方法可以快速密码,但此方法设置的密码使用history命令可以看到,所以不太推荐
[root@iZ2864f6btwZ ~]# mysqladmin -u root password 'newpassword'
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.
