shell脚本一键安装MySQL5.5

执行脚本之前必须下载MySQL5.5二进制压缩安装包。我是事先下载好了的。下边执行shell脚本。

#!/bin/bash
#auth:taoyake
/bin/mkdir -p /taokey/tools
cd /taokey/tools/
tar -zxf mysql-5.5.32-linux2.6-x86_64.tar.gz
sleep 3
cp -R mysql-5.5.32-linux2.6-x86_64 /usr/local/mysql
sleep 3
cd /usr/local/mysql/
/bin/mkdir -p /var/lib/mysql
cp support-files/my-large.cnf /var/lib/mysql/my.cnf
useradd -M -s /sbin/nologin mysql
chown -R mysql.mysql /var/lib/mysql
sed -i '40 s/^/datadir = \/var\/lib\/mysql\n/' /var/lib/mysql/my.cnf
yum install -y libaio >/dev/null 2>&1
sleep 2
/usr/local/mysql/scripts/mysql_install_db --defaults-file=/var/lib/mysql/my.cnf --user=mysql
/usr/local/mysql/bin/mysqld_safe --defaults-file=/var/lib/mysql/my.cnf &
sleep 5
/usr/local/mysql/bin/mysql -u root -S /tmp/mysql.sock -e "select version();"
if [ "$?" -eq "0" ]
then
echo -e "\e[1;32m MySQL-5.5 install Success! \e[0m"
else
echo -e "\e[1;31m MySQL-5.5 install Fail! \e[0m"
fi

执行shell脚本：

[root@db_server ~]# sh mysql_script.sh
WARNING: The host 'db_server' could not be looked up with resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MySQL version. The MySQL daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MySQL privileges !
Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h db_server password 'new-password'

Alternatively you can run:
./bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd ./mysql-test ; perl mysql-test-run.pl

Please report any problems with the ./bin/mysqlbug script!
