CentOS7源码编译安装MySQL5.7

2024年2月15日 131次阅读 来源: 驸马叶子

一、安装准备

二、下载MySQL

在MySQL下载页，选择MySQL的版本。

  1. 选择版本 MySQL Community Server 5.7.23
  2. 选择 Source Code
  3. 选择 Generic Linux (Architecture Independent)
  4. 选择带boost版本的 mysql-boost-5.7.23.tar.gz
  5. 复制链接地址

下载MySQL

yum -y install wget
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-boost-5.7.23.tar.gz

三、环境依赖

源码方式安装MySQL所需的环境依赖：

  • cmake
  • make
  • gcc
  • gcc-c++
  • bison
  • ncurses
  • ncurses-devel（devel是开发版本）
yum -y install cmake make gcc gcc-c++ bison ncurses ncurses-devel

四、安装MySQL

1. 解压mysql包

tar -zxvf mysql-boost-5.7.23.tar.gz
cd mysql-5.7.23/

2. 创建编译目录

mkdir configure
cd configure

3. 生成编译环境

cmake .. -DWITH_BOOST=../boost/boost_1_59_0/ -DWITH_EMBEDDED_SERVER=OFF

结果：

-- Configuring done
-- Generating done
-- Build files have been written to: /root/mysql-5.7.23/configure

可能遇到的问题：

  • 问题1
MySQL currently requires boost_1_59_0...

解决：因为下载的带boost的版本，只需指定正确的 -DWITH_BOOST 参数即可，如下

-DWITH_BOOST=../boost/boost_1_59_0/

如果是不带boost的版本，需要自己下载，并移动至解压的mysql-5.7.23目录下，在生成编译文件时，指定正确的 -DWITH_BOOST 参数即可

wget https://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz/download
tar -zxvf boost_1_59_0.tar.gz
mv boost_1_59_0 mysql-5.7.23

或者指定cmake参数，系统会自己下载

-DDOWNLOAD_BOOST=1 -DWITH_BOOST
  • 问题2
make[2]: *** [libmysqld/examples/mysql_client_test_embedded] 错误 1
make[1]: *** [libmysqld/examples/CMakeFiles/mysql_client_test_embedded.dir/all] 错误 2

解决：添加以下参数

-DWITH_EMBEDDED_SERVER=OFF

4. 编译安装

整个过程可能需要点时间，耐心等待。

make && make install

5. 创建mysql用户组和用户

groupadd mysql
useradd -g mysql mysql

6. 设置权限

MySQL的安装目录为 /usr/local/mysql

chown -R mysql:mysql /usr/local/mysql

7. 初始化数据库

cd /usr/local/mysql/bin
./mysqld --initialize --user=mysql

2018-07-29T19:09:18.304497Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2018-07-29T19:09:18.536280Z 0 [Warning] InnoDB: New log files created, LSN=45790
2018-07-29T19:09:18.586523Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
2018-07-29T19:09:18.649604Z 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: e49ee151-9362-11e8-ab75-08002739fe2b.
2018-07-29T19:09:18.653045Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.
2018-07-29T19:09:18.653886Z 1 [Note] A temporary password is generated for root@localhost: A,uNFfDrd1yd

结果：生成了一个临时密码，这个要记录下来。同时有个警告

TIMESTAMP with implicit DEFAULT value is deprecated。

解决：

vim /etc/my.cnf

编辑配置文件，然后将 explicit_defaults_for_timestamp=true 写入其中。

8. 将mysql加入系统服务

cd /usr/local/mysql/support-files
cp mysql.server /etc/init.d/mysql
chkconfig --add mysql # 加入系统服务
chkconfig mysql on # 开机启动

9. 尝试开启MySQL服务

service mysql start

遇到问题，如下：

Starting MySQL.2018-07-30T01:14:39.000931Z mysqld_safe error: log-error set to '/var/log/mariadb/mariadb.log', however file don't exists. Create writable for user 'mysql'.
 ERROR! The server quit without updating PID file (/var/lib/mysql/localhost.localdomain.pid).

解决：创建该文件即可

mkdir /var/log/mariadb
touch /var/log/mariadb/mariadb.log
chown -R mysql:mysql /var/log/mariadb/mariadb.log

再次开启mysql服务

[root@localhost support-files]# service mysql start
Starting MySQL. SUCCESS!

服务开启成功了!

10. 登录mysql

[root@localhost support-files]# mysql -u root -p
-bash: mysql: 未找到命令

解决未找到命令问题

创建软链接

ln -s /usr/local/mysql/bin/mysql /usr/local/bin

结果：

[root@localhost ~]# ll -a /usr/local/bin
总用量 0
drwxr-xr-x.  2 root root  19 7月  30 16:36 .
drwxr-xr-x. 15 root root 169 7月  30 02:58 ..
lrwxrwxrwx.  1 root root  26 7月  30 16:36 mysql -> /usr/local/mysql/bin/mysql

再次登录：

遇到问题
[root@localhost ~]# mysql -u root -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
解决方法

查找 mysql.sock 文件，发现存在于 /var/lib/mysql/ 目录下。

[root@localhost ~]# find / -name 'mysql.sock'
/var/lib/mysql/mysql.sock

再查看配置文件 my.cnf

[mysqld]
  2 datadir=/var/lib/mysql
  3 socket=/var/lib/mysql/mysql.sock
  4 explicit_defaults_for_timestamp=true

从配置文件看出socket值为 /var/lib/mysql/mysql.sock，那么可以创建软链接到 /tmp/mysql.sock

ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
重新登录mysql

如果在初始化数据库时，没有记录生成的临时密码，那就得“暴力破解”了。

首先，关闭mysql服务

service mysql stop

接着，修改/etc/my.cnf，添加skip-grant-tables，如下

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

skip-grant-tables

然后，免密登录并修改登录密码

mysql
# 设置账户密码并退出
update user set authentication_string=password('PASSWORD') where user='root';
flush privileges;

最后，将/etc/my.cnf中的skip-grant-tables删除或注释掉。

重启服务，使用密码登录

[root@localhost support-files]# mysql -u root -p
Enter password:

提示重置自动生成的密码：

mysql> show databases;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

修改root用户的密码

mysql> alter user 'root'@'localhost' identified by '123123';
Query OK, 0 rows affected (0.00 sec)

或者

mysql> set password for root@localhost=password('123123');
Query OK, 0 rows affected, 1 warning (0.00 sec)

重新登录MySQL

mysql> exit
Bye
[root@localhost ~]# mysql -u root -p
Enter password:

五、总结

好记性不如烂笔头，得养成记录的习惯了。
