1.Centos安裝Mysql
1 --安裝 2 yum install mysql-server 卸載 yum -e mysql-server 3 --設定為開機啟動 4 chkconfig mysqld on 5 --啟動mysql 6 service mysqld start 7 --設定root密碼 8 mysqladmin -u root password ‘xxx‘ 9 #雙機熱備10 GRANT REPLICATION SLAVE ON *.* TO ‘backup‘@‘192.168.1.33‘ IDENTIFIED BY ‘backup_xxx‘;11 #一般帳號12 --GRANT ALL PRIVILEGES ON *.* TO ‘username‘@‘localhost‘ IDENTIFIED BY ‘password‘;13 flush privileges;14 亂碼:15 [mysqld]16 #add17 default-character-set = utf818 character-set-server = utf819 collation-server = utf8_general_ci20 init_connect = ‘SET collation_connection = utf_general_ci‘21 init_connect = ‘SET NAMES utf8‘22 [mysqld_safe]
2.安裝Redis
wget http://download.redis.io/releases/redis-2.8.7.tar.gz or http://download.redis.io/releases/redis-2.6.17.tar.gztar -zvxf xxxconfiguremake && make install
3.啟動memcached
memcached -d -m 100 -u root -p 11211 -P /tmp/memcached.pid
4.防火牆:
1 Iptables: 2 啟動iptables 3 service iptables start 4 iptables --list //*查看iptables規則集*// 5 下面是沒有定義規劃時iptables的樣子: 6 Chain INPUT (policy ACCEPT) 7 target prot opt source destination 8 Chain FORWARD (policy ACCEPT) 9 target prot opt source destination10 Chain OUTPUT (policy ACCEPT)11 target prot opt source destination12 如何開啟/關閉指定連接埠13 例如:14 開啟81連接埠:15 iptables -I INPUT -i eth0 -p tcp --dport 81 -j ACCEPT16 iptables -I OUTPUT -o eth0 -p tcp --sport 81 -j ACCEPT17 關閉81連接埠:18 iptables -I INPUT -i eth0 -p tcp --dport 81 -j DROP19 iptables -I OUTPUT -o eth0 -p tcp --sport 81 -j DROP20 然後儲存21 /etc/rc.d/init.d/iptables save22 你可以使用lsof命令來查看某一連接埠是否開放.查看連接埠可以這樣來使用.23 我就以81連接埠為例:24 lsof -i:8125 如果有顯示說明已經開放了.如果沒有顯示說明沒有開放
5.環境變數
1 Tomcat JVM配置--catalina.bat/catalina.sh2 windows3 set JAVA_OPTS = -Xmx512m -Xms512m -XX:MaxPermSize=256m4 linux5 JAVA_OPTS ="-server -Xmx400m -Xms400m -Xmn128m -XX:MaxPermSize=128m -XX:PermSize=128m"
6.項目直接存取
1 【Tomcat直接存取項目--去掉訪問路徑上的項目名稱】2 修改Tomcat_Home/conf/server.xml3 <Host> 下添加 <Context path="" docBase="項目路徑" reloadable="true" />4 path為訪問路徑,與request.getContextPath()傳回值一樣。
7.Nginx配置:
安裝 pcre-devel openssl-devel
