mysql源码包安装

一、准备编译环境

# yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make cmake

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

（内存不要太小）

二、准备源码包

# groupadd mysql

# useradd -r -g mysql -s /bin/false mysql （-r:系统用户，-g:组，-s:指定shell）

# tar xvf mysql-5.7.19.tar.gz

# cd mysql-5.7.19（以下都在该文件夹下完成）

[root@mysql3 mysql-5.7.19]# mv ../boost_1_59_0.tar.gz  .

[root@mysql3 mysql-5.7.19]# tar xf  boost_1_59_0.tar.gz（boost可以理解为MySQL的库文件）

配置

[root@mysql-5.7.17 ~]# cmake . \
-DWITH_BOOST=boost_1_59_0/ \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DSYSCONFDIR=/etc \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DINSTALL_MANDIR=/usr/share/man \
-DMYSQL_TCP_PORT=3306 \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_READLINE=1 \
-DWITH_SSL=system \
-DWITH_EMBEDDED_SERVER=1 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1

如果cmake失败，请将CMakeCache.txt缓存移除

编译

# make
    等待1个小时左右

安装

# make install

三、初始化

# cd /usr/local/mysql

# mkdir mysql-files

# chown -R mysql.mysql  /usr/local/mysql

#  /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

#  /usr/local/mysql/bin/mysql_ssl_rsa_setup --datadir=/usr/local/mysql/data

# vim /etc/my.cnf

[root@mysql1 mysql]# vim /etc/my.cnf
[mysqld]
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data

四、开机启动MySQL

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

# chkconfig --add mysqld

# chkconfig mysqld on

# service mysqld start

# ps aux |grep mysqld

mysql -u root -p '密码'  登陆有问题吗？

/usr/local/mysql/bin/mysql -u root -p'x/dwiQ2<l:hb'（引号内为上一步的临时密码）

配新密码

/usr/local/mysql/bin/mysqladmin -u root -p 'x/dwiQ2<l:hb' password 'QinFeng@123'

show databases; 看到库即可。

$PATH(必须做，有点的时候回报错，确保万无一失)

[root@mysql2 mysql]# mysql

-bash: mysql: command not found

[root@mysql2 mysql]# /usr/local/mysql/bin/mysql  （关键）

[root@mysql1 mysql]# echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile

[root@mysql1 mysql]# source /etc/profile

[root@localhost ~]# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 5
Server version: 5.7.19 Source distribution

五、报错记录

1、[root@localhost mysql]# service mysqld start
Starting MySQL.2019-11-02T11:02:31.316199Z mysqld_safe error: log-error set to '/var/lble for user 'mysql'.
 ERROR! The server quit without updating PID file (/usr/local/mysql/data/localhost.pid）
[root@localhost mysql]# mkdir /var/lo
local/ lock/  log/   
[root@localhost mysql]# mkdir /var/log/mariadb
[root@localhost mysql]# touch /var/log/mariadb/mariadb.log
[root@localhost mysql]# chown -R mysql:db /var/log/mariadb
chown: invalid group: ‘mysql:db’
[root@localhost mysql]# chown -R mysql:mysql /var/log/mariadb/
[root@localhost mysql]#
[root@localhost mysql]# service mysqld start
Starting MySQL. SUCCESS!

2、[root@localhost ~]# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)

解决：[root@localhost ~]# yum -y install mariadb mariadb-server

[root@localhost ~]# systemctl restart mariadb
[root@localhost ~]# mysql
