一、编译安装第一个MySQL 5.1.33
?
|
|
cd
/opt
/usr/sbin/groupadd
mysql
/usr/sbin/useradd
-g mysql mysql -s
/bin/nologin
-d
/usr/local/mysql
tar
-zxvf mysql-5.1.33.
tar
.gz
cd
mysql-5.1.33/
.
/configure
--prefix=
/usr/local/mysql/
--
enable
-assembler --with-extra-charsets=complex --
enable
-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --
enable
-
local
-infile --with-plugins=innobase
make
&&
make
install
chmod
+w
/usr/local/mysql
chown
-R mysql:mysql
/usr/local/mysql
cp
support-files
/my-medium
.cnf
/usr/local/mysql/my
.cnf
cd
../
|
附：以下为附加步骤，如果你想在这台服务器上运行MySQL数据库，则执行以下两步。如果你只是希望让PHP支持MySQL扩展库，能够连接其他服务器上的MySQL数据库，那么，以下两步无需执行。
①、以mysql用户帐号的身份建立数据表：
?
|
1
|
/usr/local/mysql/bin/mysql_install_db
--basedir=
/usr/local/mysql
--datadir=
/usr/local/mysql/data
--user=mysql
|
②、启动MySQL（最后的&表示在后台运行）
?
|
|
/bin/sh
/usr/local/mysql/bin/mysqld_safe
--defaults-
file
=
/usr/local/mysql/my
.cnf &
echo
"/bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/usr/local/mysql/my.cnf &"
>>
/etc/rc
.
local
ln
-s
/usr/local/mysql/bin/mysql
/sbin/mysql
ln
-s
/usr/local/mysql/bin/mysqladmin
/sbin/mysqladmin
mysqladmin -u root password 1234 --初始化root密码
mysqladmin -u root -p password 456 --修改root已设置好的密码
mysql -u root -p --用新密码连接数据库
|
添加mysql帐户
?
|
|
grant all on *.* to
'mysql3306'
@
'%'
identified by
'mysql3306'
; --添加用户mysql3306用于远程管理mysql数据库
|
二、编译安装第二个mysql 5.1.33:
注:可以将第一个mysql的安装文件全部复制过来,为了熟练安装过程,这里就再来重新安装一遍
?
|
|
cd
/opt
/usr/sbin/useradd
-g mysql mysql3307 -s
/bin/nologin
-d
/usr/local/mysql3307
tar
-zxvf mysql-5.1.33.
tar
.gz
cd
mysql-5.1.33/
.
/configure
--prefix=
/usr/local/mysql3307/
--
enable
-assembler --with-extra-charsets=complex --
enable
-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --
enable
-
local
-infile --with-plugins=innobase
make
;
make
install
chmod
+w
/usr/local/mysql3307
chown
-R mysql3307:mysql
/usr/local/mysql3307
chmod
-R 777
/usr/local/mysql3307
cp
/usr/local/mysql/share/mysql/my-medium
.cnf
/usr/local/mysql3307/my
.cnf
|
修改配置文件:
?
|
|
port = 3307 --修改端口
socket =
/tmp/mysql3307
.sock --修改sock
# Here follows entries for some specific programs
# The MySQL server
[mysqld]
port = 3307
socket =
/tmp/mysql3307
.sock
|
①、以mysql用户帐号的身份建立数据表：
?
|
1
|
/usr/local/mysql3307/bin/mysql_install_db
--basedir=
/usr/local/mysql3307
--datadir=
/usr/local/mysql3307/data
--user=mysql3307
|
②、启动MySQL（最后的&表示在后台运行）
?
|
|
/bin/sh
/usr/local/mysql3307/bin/mysqld_safe
--defaults-
file
=
/usr/local/mysql3307/my
.cnf &
echo
"/bin/sh /usr/local/mysql3307/bin/mysqld_safe --defaults-file=/usr/local/mysql3307/my.cnf &"
>>
/etc/rc
.
local
|
注:如出现 warning world-writable config file ' /usr/local/mysql3307/my.cnf' is ignored
解决办法: chmod 644 /usr/local/mysql3307/my.cnf
?
|
|
mysqladmin -P 3307 -S
/tmp/mysql3307
.sock -u root password 1q2w3e --初始化root密码
mysqladmin -P 3307 -S
/tmp/mysql3307
.sock -u root -p password 1q2w3e --修改root已设置好的密码
/usr/local/mysql3307/bin/mysql
-uroot -p -S
/tmp/mysql3307
.sock
|
添加mysql帐户
?
|
|
grant all on *.* to
'mysql3307'
@
'%'
identified by
'mysql3307'
; --添加用户mysql3307用于远程管理mysql数据库
