源码安装 mysql-5.7.24

1）官网下载地址：https://dev.mysql.com/downloads/mysql/

  此处下载的是 mysql-boost-5.7.24.tar.gz

2）安装依赖包

yum list|grep ncurses-devel
yum -y install make gcc-c++ cmake bison-devel ncurses-devel

3）创建安装目录

mkdir /usr/local/mysql      安装目录
mkdir -p /data/3306/data  存放数据目录
mkdir /data/3306/binlog/

4）编译

cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \   
-DMYSQL_DATADIR=/data/3306/data \
-DSYSCONFDIR=/data/3306 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DMYSQL_UNIX_ADDR=/data/3306/mysql.sock \
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8mb4 \
-DDEFAULT_COLLATION=utf8mb4_general_ci

编译会报错

 CMake Error at cmake/boost.cmake:81 (MESSAGE):
  You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=

  This CMake script will look for boost in .  If it is not there,
  it will download and unpack it (in that directory) for you.

  If you are inside a firewall, you may need to use an http proxy:

解决方法：

mkdir /usr/local/boost
cd /usr/local/boost
wget http://www.sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
tar zxvf boost_1_59_0.tar.gz

重新编译并加最后一条参数

cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \     安装根目录
-DMYSQL_DATADIR=/data/3306/data \                 数据存储目录
-DSYSCONFDIR=/data/3306 \                               配置文件(my.cnf)目录
-DWITH_MYISAM_STORAGE_ENGINE=1 \               编译myisam存储引擎，默认的存储引擎，不加也可以
-DWITH_INNOBASE_STORAGE_ENGINE=1 \             支持InnoDB存储引擎，这个也是默认安装的
-DWITH_MEMORY_STORAGE_ENGINE=1 \               支持MEMORY引擎 
-DWITH_READLINE=1 \                                            使用readline功能
-DMYSQL_UNIX_ADDR=/data/3306/mysql.sock \     sock存放到/data/3306目录
-DMYSQL_TCP_PORT=3306 \                        数据库端口
-DENABLED_LOCAL_INFILE=1 \                      可以使用load data infile命令从本地导入文件
-DWITH_PARTITION_STORAGE_ENGINE=1 \      安装数据库分区
-DEXTRA_CHARSETS=all \                              支持所有字符集
-DDEFAULT_CHARSET=utf8mb4 \                    默认字符集
-DDEFAULT_COLLATION=utf8mb4_general_ci \       设置默认效验字符集排序规则，要和DDEFAULT_CHARSET一起用
-DWITH_BOOST=/usr/local/boost    从MySQL 5.7.5开始Boost库是必需的

5）安装

make && make install
make clean

6）添加用户和组

groupadd mysql
useradd -g mysql mysql
chown -R mysql:mysql /usr/local/mysql
chown -R mysql:mysql /data/3306

7）实例初始化

cd /usr/local/mysql
./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/3306/data/  初始化完了需要记住root密码

出现以下说明初始化成功
2018-11-12T01:25:29.316210Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
source /etc/profile
SET PASSWORD = PASSWORD('*********');

在5.7.6之前初始化的方法是：bin/mysql_install_db

5.7.6之后的版本初始化数据库不再使用mysql_install_db，而是使用： bin/mysqld --initialize

8）配置数据库

复制启动文件

cp support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
cp bin/my_print_defaults /usr/bin/ 

修改启动脚本

vi /etc/init.d/mysqld
修改项为图中方框的部分

修改mysql配置项

vi /etc/my.cnf

配置如下：

[mysqld]
basedir = /usr/local/mysql
datadir = /data/3306/data/
socket = /data/3306/mysql.sock
user = mysql
tmpdir = /data/3306/
symbolic-links=0

[mysqld_safe]

log-error = /data/3306/data/error.log
pid-file = /data/3306/data/mysql.pid

启动mysql

service mysqld start

ps -ef|grep mysql
root      2644   488  0 10:21 pts/1    00:00:00 grep --color=auto mysql
root     24581     1  0 00:19 ?        00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/data/3306/data/ --pid-file=/data/3306/data//k8s-test-master.pid
mysql    24769 24581  0 00:19 ?        00:00:08 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/data/3306/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/data/3306/data/error.log --pid-file=/data/3306/data//k8s-test-master.pid --socket=/data/3306/mysql.sock

9)修改密码

现在是可以登录了但发现需要密码，原来5.7后MySQL会生成一个随机密码，

我没有找到存放密码的文件，就只能去强制修改密码了。

在my.cnf中加上skip-grant-tables后 service mysqld restart

修改完成后发现可以不用密码直接登录

登录后执行

update mysql.user set authentication_string=password(‘123456’) where user=‘root’;

flush privileges;

执行成功后将my.cnf 文件改回去，重启MySQL，使用新密码登录，MySQL已安装完成。

---

安装完mysql 之后，登陆以后，不管运行任何命令，总是提示这个

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

解决方法如下三步：

step 1: SET PASSWORD = PASSWORD(‘your new password’);

step 2: ALTER USER ‘root’@‘localhost’ PASSWORD EXPIRE NEVER;

step 3: flush privileges;

完成以上三步退出再登，使用新设置的密码就行了，以上除了第一步修改成新密码外，其他原样输入即可
