Linux服务器软件安装备忘
1.Centos安装Mysql
1 --安装 2 yum install mysql-server 卸载 yum -e mysql-server 3 --设置为开机启动 4 chkconfig mysqld on 5 --启动mysql 6 service mysqld start 7 --设置root密码 8 mysqladmin -u root password 'xxx' 9 #双机热备 10 GRANT REPLICATION SLAVE ON *.* TO 'backup'@'192.168.1.33' IDENTIFIED BY 'backup_xxx'; 11 #一般账号 12 --GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' IDENTIFIED BY 'password'; 13 flush privileges; 14 乱码： 15 [mysqld] 16 #add 17 default-character-set = utf8 18 character-set-server = utf8 19 collation-server = utf8_general_ci 20 init_connect = 'SET collation_connection = utf_general_ci' 21 init_connect = 'SET NAMES utf8' 22 [mysqld_safe]
2.安装Redis
wget http://download.redis.io/releases/redis-2.8.7.tar.gz or http://download.redis.io/releases/redis-2.6.17.tar.gz tar -zvxf xxx configure make && make install
3.启动memcached
memcached -d -m 100 -u root -p 11211 -P /tmp/memcached.pid
4.防火墙：
1 Iptables: 2 启动iptables 3 service iptables start 4 iptables --list //*查看iptables规则集*// 5 下面是没有定义规划时iptables的样子: 6 Chain INPUT (policy ACCEPT) 7 target prot opt source destination 8 Chain FORWARD (policy ACCEPT) 9 target prot opt source destination 10 Chain OUTPUT (policy ACCEPT) 11 target prot opt source destination 12 如何开启/关闭指定端口 13 例如: 14 开启81端口： 15 iptables -I INPUT -i eth0 -p tcp --dport 81 -j ACCEPT 16 iptables -I OUTPUT -o eth0 -p tcp --sport 81 -j ACCEPT 17 关闭81端口： 18 iptables -I INPUT -i eth0 -p tcp --dport 81 -j DROP 19 iptables -I OUTPUT -o eth0 -p tcp --sport 81 -j DROP 20 然后保存 21 /etc/rc.d/init.d/iptables save 22 你可以使用lsof命令来查看某一端口是否开放.查看端口可以这样来使用. 23 我就以81端口为例： 24 lsof -i:81 25 如果有显示说明已经开放了.如果没有显示说明没有开放
5.环境变量
1 Tomcat JVM配置--catalina.bat/catalina.sh 2 windows 3 set JAVA_OPTS = -Xmx512m -Xms512m -XX:MaxPermSize=256m 4 linux 5 JAVA_OPTS ="-server -Xmx400m -Xms400m -Xmn128m -XX:MaxPermSize=128m -XX:PermSize=128m"
6.项目直接访问
1 【Tomcat直接访问项目--去掉访问路径上的项目名称】 2 修改Tomcat_Home/conf/server.xml 3 <Host> 下添加 <Context path="" docBase="项目路径" reloadable="true" /> 4 path为访问路径，与request.getContextPath()返回值一样。
7.Nginx配置：
安装 pcre-devel openssl-devel
1 http{ 2 #... 3 gzip on; 4 gzip_min_length 1k; 5 gzip_buffers 16 64k; 6 gzip_http_version 1.1; 7 gzip_comp_level 4; 8 gzip_types text/plain text/css application/xml image/png; #... 9 gzip_vary on; 10 sendfile on; 11 client_max_body_size 1024m;#附件上传 12 upstream e_learning{ 13 server 192.168.1.30:8080; 14 server 192.168.1.31:8080; 15 ip_hash; 16 } 17 server{ 18 listen 80; 19 server_name 192.168.1.34; 20 index index.jsp; 21 location / { 22 index index.jsp; 23 proxy_pass http://e_learning; 24 proxy_set_header Host $host; 25 proxy_set_header X-Real_IP $remote_addr; 26 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 27 } 28 location ^~ /upload/ { 29 expires 10d; 30 root /var/e_learning; 31 } 32 location ^~ /vod { 33 proxy_pass http://192.168.1.36:1935/vod/; 34 proxy_set_header Host $host; 35 proxy_set_header X-Real_IP $remote_addr; 36 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 37 } 38 location ~*\.(gif|jpg|png|js|css)$ { 39 expires 10d; 40 proxy_pass http://e_learning; 41 proxy_set_header Host $host; 42 proxy_set_header X-Real_IP $remote_addr; 43 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 44 } 45 } 46 }
