一、安裝mysql
[[email protected] ~]#tar -zxvf bison-2.5.tar.gz
[[email protected] ~]#./configure && make&& make install
[[email protected] ~]#tar -zxvf cmake-2.8.7.tar.gz
[[email protected] ~]#./bootstrap && gmake && gmake install
[[email protected] ~]#tar -zxvf mysql-5.5.22.tar.gz
[[email protected] ~]#cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -
DSYSCONFDIR=/etc/ -DDEFAULT_CHARSET=utf8 -
DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all
[[email protected] ~]#make && make install
初始化mysql:
[[email protected] ~]# cp support-files/my-medium.cnf /etc/my.cnf
[[email protected]st ~]# cd scripts
[[email protected] ~]# ./mysql_install_db --basedir=/usr/local/mysql/ --
datadir=/usr/local/mysql/data/ --user=mysql
[[email protected] ~]# cp ../support-files/mysql.server /etc/init.d/mysqld
[[email protected] ~]# ln -s /usr/local/mysql/bin/* /usr/local/bin/
[[email protected] ~]# mysqladmin -u root password ‘redhat‘
登入測試:
[[email protected] ~]# mysql -u root -p
建立資料庫:
[[email protected] ~]# mysql> createdata server1;
當然你也可以使用yum的方式安裝mysql
[[email protected] ~]# yum -y install mysql mysql-devel mysql-server
二、安裝haproxy
1、安裝
[[email protected] ~]# yum -y install pcre-devel zlib-devel
[[email protected] ~]# tar -zxvf haproxy-1.4.24.tar.gz -C /usr/src/
[[email protected] ~]# cd /usr/src/haproxy-1.4.24/
[[email protected] ~]# make TARGET=linux26 PREFIX=/usr/local/haproxy
注意:linux26 是指linux 的核心版本號碼。
[[email protected] ~]# make install PREFIX=/usr/local/haproxy
2、配置haproxy
[[email protected] ~]# mkdir /etc/haproxy
[[email protected] ~]# cp /usr/src/haproxy-1.4.24/examples/haproxy.cfg /etc/haproxy/
[[email protected] ~]# vim /etc/haproxy/haproxy.cfg
修改:
global
log 127.0.0.1 local0 //配置日誌記錄,local0 為日誌裝置,預設存放到系統日誌
log 127.0.0.1 local1 notice //notice 為記錄層級,通常有7 個層級
#log loghost local0 info
maxconn 4096 //預設最大串連數,需考慮ulimit-n 限制 :可增加ulimitn
819200 #ulimit 的數量限制
chroot /usr/share/haproxy //運行路徑
uid 99
gid 99
#debug
#quiet
defaults
log global //定義日誌為global 中的日誌
mode tcp //模式為四層
option tcplog //採用http 的日誌格式
option dontlognull //不記錄健全狀態檢查日誌資訊
retries 3 //三次串連失敗就認為是伺服器不可用,也可以通過後面設定
#redispatch
maxconn 2000 //最大串連數
contimeout 5000 //連線逾時時間
clitimeout 50000 //用戶端逾時時間
srvtimeout 50000 //服務端逾時時間
listen stats
mode http
bind :6677
stats enable
stats hide-version
stats uri /haproxyadmin?stats
stats realm Haproxy\ Statistics
stats auth admin:admin
stats admin if TRUE
listen mysqlcluster 0.0.0.0:3306
balance roundrobin
server m1 192.168.56.202:3306 check port 3306 maxconn 300
server m2 192.168.56.203:3306 check port 3306 maxconn 300
注意:
如果啟動時出現報錯:/haproxy.main()] Cannot chroot(/usr/share/haproxy)
則手動建立:
[[email protected] ~]# mkdir /usr/share/haproxy
如果啟動時出現報錯:Starting proxy cacti: cannot bind socket
則執行:
[[email protected] ~]# sysctl -e net.ipv4.ip_nonlocal_bind=1
3、啟動haproxy
[[email protected] ~]# ln -s /usr/local/haproxy/sbin/* /usr/sbin/ //注意軟連結的目錄
[[email protected] ~]# cp /usr/src/haproxy-1.4.24/examples/haproxy.init
/etc/init.d/haproxy
[[email protected] ~]# chmod +x /etc/init.d/haproxy
[[email protected] ~]# /etc/init.d/haproxy start
[[email protected] ~]# /etc/init.d/haproxy status
[[email protected] ~]# netstat -anp | grep haproxy //佔用的也是TCP 的80 連接埠
[[email protected] ~]# chkconfig --add haproxy
[[email protected] ~]# chkconfig haproxy on
http://192.168.56.200:6677/haproxyadmin?stats 查看叢集的狀態
四、MySql 授權使用者登入(叢集內的mysql 都要授權)
mysql> GRANT ALL ON *.* TO ‘root‘@‘192.168.56.%‘ IDENTIFIED BY ‘redhat‘;
mysql> flush privileges;
五、測試:
[[email protected] ~]# mysql -u root -h 192.168.56.200 -p
登入兩次分別查看
可增加keepalived
