CentOS7源码编译安装MySQL5.7

摘要：一安装准备官网下载页二下载在下载页，选择的版本。创建用户组和用户设置权限的安装目录为初始化数据库结果生成了一个临时密码，这个要记录下来。解决编辑配置文件，然后将写入其中。

MySQL官网 https://www.mysql.com/

MySQL下载页 https://dev.mysql.com/downloa...

在MySQL下载页，选择MySQL的版本。

选择版本 MySQL Community Server 5.7.23

选择 Source Code

选择 Generic Linux (Architecture Independent)

选择带boost版本的 mysql-boost-5.7.23.tar.gz

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

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

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

mkdir configure
cd configure

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

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

整个过程可能需要点时间，耐心等待。

make && make install

groupadd mysql
useradd -g mysql mysql

MySQL的安装目录为 /usr/local/mysql

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

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

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。

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

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!

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

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

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:

好记性不如烂笔头，得养成记录的习惯了。
