mysql-5.7.14 源码安装笔记

安装编译

下载源码

mysql-5.7.14.tar.gz

解压定义安装变量

cd /usr/local/src
mysql_version="mysql-5.7.14"
tar -zxf "${mysql_version}.tar.gz"
cd ${mysql_version}

配置

cmake \
-DCMAKE_INSTALL_PREFIX:PATH=/usr/local/services/${mysql_version} \
-DMYSQL_DATADIR:PATH=/data/${mysql_version} \
-DEXTRA_CHARSETS=all \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_READLINE=1 \
-DMYSQL_USER=mysql \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_SSL=yes

报错：

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

  This CMake script will look for boost in <directory>.  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:

  export http_proxy=http://example.com:80

Call Stack (most recent call first):
  cmake/boost.cmake:238 (COULD_NOT_FIND_BOOST)
  CMakeLists.txt:455 (INCLUDE)

解决：

mysql 依赖boost，添加编译选项：

-DDOWNLOAD_BOOST=1 \
-DWITH_BOOST=/usr/local/services/boost

备注：

1. cmake 生成的临时文件是CMakeCache.txt， 需要删除掉之前配置生成的临时文件 rm CMakeCache.txt
2. 重新进行配置检查，避免由于，更新系统软件包后，依然使用旧的临时文件，导致配置找不到相关的库。

安装

make
make install

配置启动

以下操作用户均为root

创建用户，数据库初始化

# 创建mysql运行用户
groupadd mysql
useradd -g mysql -s /sbin/nologin mysql

# 创建mysql数据目录，并授权
mkdir -p /data/${mysql_version}
chown -R mysql:mysql /usr/local/services/${mysql_version}
chown -R mysql:mysql /data/${mysql_version}

# 初始化mysql 系统数据表
# /usr/local/services/${mysql_version}/bin/mysqld \
--initialize \
--user=mysql \
--datadir=/data/${mysql_version}

# 创建配置文件
mkdir -p /usr/local/services/${mysql_version}/etc/
cp /usr/local/services/${mysql_version}/support-files/my-default.cnf /usr/local/services/${mysql_version}/etc/my.cnf

/usr/local/services/${mysql_version}/bin/mysql_ssl_rsa_setup

# 设置权限
chown -R root /usr/local/services/${mysql_version}
chown -R mysql /data/${mysql_version}

注意：

1. 配置文件 etc/my.cnf 需要配置完全，包括安装目录，数据存储目录，等...
2. 初始化数据库表, mysql-5.7.6 之后发生了变更，之前是 mysql_init_db
3. 若使用etc/my.cnf 中的配置，则需将/etc/my.cnf 中的相关的配置项注释掉

启动mysql

/usr/local/services/${mysql_version}/bin/mysqld_safe --user=mysql &

注意：

无需指定--default-file=$basedir/etc/my.cnf，mysql 有默认的配置文件加载顺序

/etc/my.cnf
basedir/etc/my.cnf

连接mysql

mysql -uroot -p

注意:

若提示无法使用xx.sock，这是因为没有指定连接的sock，可配置my.cnf，指定连接的sock

[client]
socket=/data/${mysql_version}/mysql.sock

更新root密码

update mysql.user set password=password('123456') where user='root';

报错：

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

解决：

SET PASSWORD = PASSWORD('123456');

关闭mysql

/usr/local/services/${mysql_version}/bin/mysqladmin shutdown -uroot -p

设置启动项

cp support-files/mysql.server /etc/init.d/mysql.server
