Node1 node2 compilation and installation of nginx (refer to node6 node7)

Node1 node2 compile and install PHP-FPM (php-5.4.19)

. /Configure -- prefix =/usr/local/PHP -- With-mysql = mysqlnd -- With-OpenSSL -- With-mysqli = mysqlnd -- enable-mbstring -- With-FreeType-dir --- JPEG-dir -- With-PNG-dir -- With-zlib -- With-libxml-Dir =/usr -- enable-XML -- enable-sockets -- enable-FPM -- With-config-File -Path =/etc -- With-config-file-scan-Dir =/etc/PHP. D -- with-bz2 -- enable-maintainer-ZTS

Make & make install

The Startup Script cp sapi/FPM/init. d. php-FPM/etc/init. d/PHP-FPM is provided.

Provide the configuration file cp php. ini-production/etc/PHP. ini for PHP

Provide the configuration file CP/usr/local/PHP/etc/php-fpm.conf.default/usr/local/PHP/etc/php-fpm.conf for PHP-FPM

Node1 Node 2 RPM install drbd83-8.3.13-2.el5.centos kmod-drbd83-8.3.13-1.el5.centos

Node3 node4 general binary method for installing mysql-5.5.37

1. Create a MySQL. MySQL user and group, CP support-files/my-huge.cnf/etc/My. CNF provides the configuration file

2. initialize/script/mysql_install_db -- user = MySQL -- datadir =/mydata/Data

3. For security consideration, the owner of the directory is changed back to root after initialization, and the group is MySQL. The data directory is in the MySQL group.

4./support-files/MySQL. server startup script

5. Library, header, and help file output

Node8 node9 Yum installation memcached-1.4.4-3.el6.x86_64

Node8 node9 universal binary installation mysql-proxy-0.8.4

1. Extract the package to/usr/local/and create a MySQL-proxy soft connection under/usr/local.

2. Create a MySQL-proxy user to run mysql-proxy

3. Provide the sysv Service Startup Script For MySQL-proxy, as shown in the following figure.

#!/bin/bash## mysql-proxy This script starts and stops the mysql-proxy daemon## chkconfig: - 78 30# processname: mysql-proxy# description: mysql-proxy is a proxy daemon for mysql# Source function library.. /etc/rc.d/init.d/functionsprog="/usr/local/mysql-proxy/bin/mysql-proxy"# Source networking configuration.if [ -f /etc/sysconfig/network ]; then    . /etc/sysconfig/networkfi# Check that networking is up.[ ${NETWORKING} = "no" ] && exit 0

4. Provide the configuration file/etc/sysconfig/MySQL-proxy for the service script

# Options for mysql-proxy ADMIN_USER="admin"ADMIN_PASSWORD="admin"ADMIN_ADDRESS=""ADMIN_LUA_SCRIPT="/usr/local/mysql-proxy/share/doc/mysql-proxy/admin.lua"PROXY_ADDRESS=""PROXY_USER="mysql-proxy"PROXY_OPTIONS="--daemon --log-level=info --log-use-syslog"

The last line needs to be modified according to the actual scenario, for example:

Proxy_options = "-- daemon -- log-level = info -- log-use-syslog -- plugins = proxy -- plugins = admin -- proxy-backend-addresses = 172.16.100.6: 3306 -- proxy-read-only-backend-addresses = 172.16.100.7: 3306 -- proxy-LUA-script =/usr/local/MySQL-proxy/share/doc/MySQL-proxy/rw-splitting.lua"

Ii. Functions

1. Implement the MySQL master-slave architecture

Edit node3 my. CNF configuration file and add the following

Server-id = 1

Datadir =/mydata/Data

Innodb_file_per_table = 1

Log_bin =/mydata/data/MySQL-bin-Log

Node3 authorizes a slave node user

Grant replication slave, replication client on *. * to [email protected] "10.32.9. %" identified by "RedHat ";

Edit node4 my. CNF configuration file and add it to/from

Server-id = 2 --- different from node3 server-ID

Datadir =/mydata/Data --- specify the data directory

Innodb_file_per_table = 1 --- InnoDB Storage engine per table space

Relay_log =/mydata/relay. Log ---- enable and specify the relay log

Read_only = 1 ---- set slave server read-only

Node4 sets slave node replication Parameters

Change master to master_host = '10. 32.9.53 ', master_user = 'Nice', master_password = 'redhat ', master_port = 3306, master_log_file = 'mysql-bin-log.000004', master_log_pos = 107;

Node4 enables replication

Start slave
