MySQL and Apache installations have no sequencing, but PHP must be the last to be loaded

1. Install MySQL

32-bit http://syslab.comsenz.com/downloads/linux/mysql-5.1.40-linux-i686-icc-glibc23.tar.gz
64-bit http://syslab.comsenz.com/downloads/linux/mysql-5.1.40-linux-x86_64-icc-glibc23.tar.gz

Place the download file in the directory

[Email protected] ~]# cd/usr/local/src/[[email protected] src]# lsmysql-5.1.40-linux-i686-icc-glibc23.tar.gz

You can look at the file size

[Email protected] src]# du-sh mysql-5.1.40-linux-i686-icc-glibc23.tar.gz 118M Mysql-5.1.40-linux-i686-icc-glibc23.tar.gz

Extract

[Email protected] src]# tar zxvf mysql-5.1.40-linux-i686-icc-glibc23.tar.gz [[email protected] src]# Lsmysql-5.1.40-linux-i686-icc-glibc23 mysql-5.1.40-linux-i686-icc-glibc23.tar.gz

Move files to the/usr/local/mysql directory

[Email protected] src]# MV Mysql-5.1.40-linux-i686-icc-glibc23/usr/local/mysql

Add a user named MySQL, but don't log in now

[[email protected] src]# useradd-s/sbin/nologin MySQL

Create Data Save Directory

[Email protected] src]# mkdir-p/data/mysql

Assigning permissions to the directory

[Email protected] mysql]# chown-r mysql:mysql/data/mysql

I still do not understand what the meaning of this sentence, the first to write, later understand the change

[Email protected] mysql]#/scripts/mysql_install_db--user=mysql--datadir=/data/mysql

Check that the installation is successful (the command is appropriate for all, 0 indicates successful installation)

[Email protected] mysql]# echo $?0

I don't know how to write that.

[[email protected] mysql]# CP support-files/mysql.server/etc/init.d/mysqld[[email protected] mysql]# chkconfig--list The MYSQLDMYSQLD service supports Chkconfig, but it is not referenced at any level (runs "Chkconfig--add mysqld") [[email protected] mysql]# chmod 755/etc/init.d/ mysqld [[email protected] mysql]# chkconfig--add mysqld[[email protected] mysql]# chkconfig mysqld on[[email protected] m ysql]# chkconfig--list mysqld mysqld 0: Off 1: Off 2: Enable 3: Enable 4: Enable 5: Enable 6: Off

Edit the file

[Email protected] mysql]# Vim/etc/init.d/mysqld

The change is that the 2 configurations

Basedir=/usr/local/mysqldatadir=/data/mysql

Copy files and agree to overwrite

[email protected] mysql]# CP support-files/my-huge.cnf/etc/my.cnf CP: Do you want to overwrite "/etc/my.cnf"? Y

Start the service

[[Email protected] mysql]# service mysqld startstarting MySQL. success!

Or you can start it like this.

[[email protected] mysql]#/etc/init.d/mysqld restartshutting down MySQL. success! Starting MySQL. success!

2. Installing Apache

wget http://syslab.comsenz.com/downloads/linux/httpd-2.2.16.tar.gz

Place the download file in the directory

[Email protected] ~]# cd/usr/local/src/[[email protected] src]# lshttpd-2.2.16.tar.gz mysql-5.1.40-linux-i686-icc- Glibc23.tar.gz

You can look at the file size

[Email protected] src]# du-sh httpd-2.2.16.tar.gz 6.1M httpd-2.2.16.tar.gz

Extract

[Email protected] src]# tar zxvf httpd-2.2.16.tar.gz [[email protected] src]# lshttpd-2.2.16 httpd-2.2.16.tar.gz my Sql-5.1.40-linux-i686-icc-glibc23.tar.gz

Go to Catalog

[Email protected] src]# CD Httpd-2.2.16[[email protected] httpd-2.2.16]#./configure--prefix=/usr/local/apache2-- Enable-mods-shared=most--enable-so
