Mysql 源码编译安装 ( 5.5 、5.6 共存 )

简介:

如何在一台服务器同时运行两 ( 多 ) 个 MySQL 服务。

1、MySQL 5.6

shell > useradd -r -s /sbin/nologin mysql

shell > wget ftp://mirror.switch.ch/mirror/mysql/Downloads/MySQL-5.6/mysql-5.6.27.tar.gz

shell > tar zxf mysql-5.6..tar.gz
shell > cd mysql-5.6.
shell > cmake . ; make ; make install shell > chown -R root:mysql /usr/local/mysql
shell > chown -R mysql /usr/local/mysql/data shell > cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
shell > cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld shell > /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ shell > service mysqld start shell > echo "PATH=$PATH:/usr/local/mysql/bin/" >> /etc/profile
shell > source /etc/profile shell > mysql -e 'select version();' # MySQL 5.6 安装成功
+-----------+
| version() |
+-----------+
| 5.6. |
+-----------+

2、MySQL 5.5

shell > wget ftp://mirror.switch.ch/mirror/mysql/Downloads/MySQL-5.5/mysql-5.5.46.tar.gz

shell > tar zxf mysql-5.5..tar.gz
shell > cd mysql-5.5.
shell > cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql5 # 指定安装路径
shell > make ; make install shell > chown -R root:mysql /usr/local/mysql5
shell > chown -R mysql /usr/local/mysql5/data shell > cp /usr/local/mysql5/support-files/my-medium.cnf /etc/my5.cnf
shell > cp /usr/local/mysql5/support-files/mysql.server /etc/init.d/mysqld5 shell > /usr/local/mysql5/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql5/ --datadir=/usr/local/mysql5/data/ shell > vim /etc/my5.cnf # 修改端口、socket port =
socket = /tmp/mysql5.sock shell > /usr/local/mysql5/bin/mysqld_safe --defaults-file=/etc/my5.cnf & # 指定配置文件路径,启动数据库 shell > mysql -uroot -S /tmp/mysql5.sock -e 'select version();' # MySQL 5.5 安装成功
+------------+
| version() |
+------------+
| 5.5.-log |
+------------+ shell > mysql -uroot -h127.0.0. -P3307 -e 'select version();' # 或者通过指定 IP:PORT 的方式
+------------+
| version() |
+------------+
| 5.5.-log |
+------------+

3、修改启动脚本

shell > vim /etc/init.d/mysqld5 # 给启动参数指定配置文件路径 ( --defaults-file=/etc/my5.cnf )

  'start')
# Start daemon # Safeguard (relative paths, core dumps..)
cd $basedir echo $echo_n "Starting MySQL"
if test -x $bindir/mysqld_safe
then
# Give extra arguments to mysqld with the my.cnf file. This script
# may be overwritten at next upgrade.
$bindir/mysqld_safe --defaults-file=/etc/my5.cnf --datadir="$datadir" --pid-file="$mysqld_pid_file_path" $other_args >/dev/null >& &
wait_for_pid created "$!" "$mysqld_pid_file_path"; return_value=$? # Make lock for RedHat / SuSE
if test -w "$lockdir"
then
touch "$lock_file_path"
fi exit $return_value
else
log_failure_msg "Couldn't find MySQL server ($bindir/mysqld_safe)"
fi
;; shell > service mysqld5 stop # OK,我们也可以使用脚本管理 MySQL 5.5 啦!
