MySQL源代码安装

标签（空格分隔）： mysql

---

前置准备

关闭防火墙： 
　　　　service iptables stop （临时关闭）
　　　　chkconfig iptables off （重启后生效）
关闭SELINUX: 
　　　　setenforce 0 （临时生效）　　
　　　　修改 /etc/selinux/config 下的 SELINUX=disabled （重启后永久生效）
        sestatus  检查状态

root用户执行安装组件

# yum -y install  gcc gcc-c++ gcc-g77 autoconf automake ncurses-devel cmake
# yum -y install wget gcc gcc-c++ cmake libaio-devel bison ncurses-devel perl-Data-Dumper
# mkdir -p /data/database/mysql   #MySQL安装目录  
# mkdir -p /data/database/mysql/data #存放数据  
# mkdir -p /data/database/mysql/log  #存放日志  
# mkdir -p /data/database/mysql/tmp  #存放临时文件  
# mkdir -p /data/database/mysql/data/log

• 查看当前用户所在组并授权用户

# groupadd mysql 
# useradd -r -g mysql -s /sbin/nologin mysql
# chown -R mysql.mysql /data/database/mysql

• 普通应用账号安装MySQL

$ tar -xzvf mysql-boost-5.7.20.tar.gz
$ cd mysql-5.7.20/

• 编译MySQL

$ cmake . \  
 -DCMAKE_INSTALL_PREFIX=/data/database/mysql \  
 -DSYSCONFDIR=/data/database/mysql
 -DMYSQL_DATADIR=/data/database/mysql/data \  
 -DMYSQL_TCP_PORT=3336

 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \  
 -DWITH_MYISAM_STORAGE_ENGINE=1 \  
 -DENABLED_LOCAL_INFILE=1 \  
 -DENABLE_DTRACE=0 \

 -DWITH_EMBEDDED_SERVER=1  
 -DDOWNLOAD_BOOST=1 \  
 -DWITH_BOOST=/data/database/mysql-5.7.20/boost \ 

• 安装

$ make && make install

• 修改my.cnf配置文件

$ cd /data/database/mysql/
$ vim my.cnf
内容如下：

### Server id ####

• 主从复制相关

# 不同步哪些数据库  
binlog-ignore-db = mysql  
binlog-ignore-db = information_schema  
# 只同步哪些数据库，除此之外，其他不同步  
# binlog-do-db = urmp  
# 日志保留时间  
expire_logs_days = 30  
# 控制binlog的写入频率。每执行多少次事务写入一次  
# 这个参数性能消耗很大，但可减小MySQL崩溃造成的损失  
sync_binlog = 5

• 将my.cnf覆盖/etc/my.cnf（需要root权限）

$ cp my.cnf  /etc/

• 初始化数据库

$ cd /data/database/mysql/
$ scripts/mysql_install_db --user=urmp --basedir=/data/database/mysql --datadir=/data/database/mysql/data
--defaults=/etc/my.cnf

• 启动数据库

$ bin/mysqld_safe  --defaults-file=/data/database/mysql/my.cnf

• 修改数据库密码

$ bin/mysqladmin -u root password 'Xianzai.123'
$ bin/mysql -uroot -pXianzai.123
mysql>update mysql.user set password=password('Xianzai.123') where  user='root';flush privileges;
mysql>select host,user,password from mysql.user;

• 关闭数据库

$ bin/mysqladmin -uroot -p shutdown

• 添加MySQL至用户环境变量

$ vim ~/.bash_profile

新增

export MYSQL_HOME=/data/database/mysql
PATH=$PATH:$MYSQL_HOME/bin

$ source ~/.bash_profile

• 将MySQL添加至系统服务（需要root权限）

$ cp support-files/mysql.server /etc/rc.d/init.d/mysqld #把Mysql加入系统启动  
$ chmod 755 /etc/init.d/mysqld #增加执行权限  
$ chkconfig mysqld on #加入开机启动

• 重启数据库连接测试

$ cd $MYSQL_HOME
$ bin/mysql -uroot -pXianzai.123

修改远程连接（======从机不可放开此设置======）

mysql>use mysql;
mysql>update mysql.user set host='%' where user='root' and host='localhost';flush privileges;
mysql>grant all privileges  on *.* to root@'%' identified by "Xianzai.123";flush privileges;

MySQL5.7安装注意事项

MySQL 5.7 需要CMake 2.8.2，查看当前cmake版本

# cmake --version

cmake version 2.6-patch 4

• 下载安装cmake
• 下载地址https://cmake.org/download/

# tar zxvf cmake-3.6.3.tar.gz
# cd cmake-3.2.2/
# ./bootstrap
# make && make install
# cmake --version

cmake version 3.6.3

• MySQL5.7 CMake编译需要boost类库，可使用 -DDOWNLOAD_BOOST=1 -DWITH_BOOST= 参数将在指定路径查找

cd /usr/local/boost

wget http://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz

tar xfz /usr/local/boost/boost_1_59_0.tar.gz

• 编译MySQL 5.7

$ cmake . 增加两个参数  -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost
