Linux（centos 7）配置tomcat8、JDK1.8、lighttpd、ngnix、mysql

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　JDK

下载好后使用 rpm -ivh jdk-7u25-linux-x64.rpm 进行安装。

安装好后编辑 /etc/profile 文件，在末尾加上：

然后保存退出，接着使用以下命令让环境变量生效：

Shell

最后执行 javac 命令以检查是否正确配置。

centos7下tomcat7 或tomcat8启动超慢原因

1，找到你的jdk安装的位置

[html] view plain copy

1. ${JAVA_HOME}/jre/lib/security/java.security

2，vi 打开后找到

[html] view plain copy

1. securerandom.source=file:/dev/urandom

修改

[html] view plain copy

1. securerandom.source=file:/dev/./urandom

3，重新启动tomcat就好了

Tomcat

下载好安装包，解压到/home/apache-tomcat-7.0.67下

(解压
tar –xvf file.tar //解压 tar包
tar -xzvf file.tar.gz //解压tar.gz
tar -xjvf file.tar.bz2   //解压 tar.bz2
tar –xZvf file.tar.Z   //解压tar.Z
unrar e file.rar //解压rar
unzip file.zip //解压zip

)

设置Tomcat为Service

设置Tomcat开机自启动 (前提是已经设置Tomcat为Service)

这个时候查看当前可用的mysql安装资源：

[[email protected] ~]# yum repolist enabled | grep "mysql.*-community.*"
mysql-connectors-community/x86_64 MySQL Connectors Community                  17
mysql-tools-community/x86_64      MySQL Tools Community                       31
mysql56-community/x86_64          MySQL 5.6 Community Server                 199

一般来说，只要安装mysql-server跟mysql-client
这个时候我们可以直接使用yum的方式安装MySQL了

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we‘ll need the current
password for the root user.  If you‘ve just installed MySQL, and
you haven‘t set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] y        [设置root用户密码]
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y            [删除匿名用户]
 ... Success!

Normally, root should only be allowed to connect from ‘localhost‘.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] n            [禁止root远程登录]
 ... skipping.

By default, MySQL comes with a database named ‘test‘ that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y       [删除test数据库]
 - Dropping test database...
ERROR 1008 (HY000) at line 1: Can‘t drop database ‘test‘; database doesn‘t exist
 ... Failed!  Not critical, keep moving...
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y        [刷新权限]
 ... Success!

All done!  If you‘ve completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!

Cleaning up...

Install Lighttpd

使用包管理器安装

这里我们通过使用包管理器这种最简单的方法来安装 Lighttpd。只需以 sudo 模式在终端或控制台中输入下面的指令即可。

CentOS 7

由于 CentOS 7.0 官方仓库中并没有提供 Lighttpd，所以我们需要在系统中安装额外的软件源 epel 仓库。使用下面的 yum 指令来安装 epel。

# yum install epel-release

然后，我们需要更新系统及为 Lighttpd 的安装做前置准备。

# yum update

# yum install lighttpd

开启服务

现在，通过执行 systemctl 指令来重启 Web 服务。

# systemctl start lighttpd

systemctl stop lighttpd

然后我们将它设置为伴随系统启动自动运行。

# systemctl enable lighttpd

##  Basic Configuration

## ---------------------

##

server.port = 80

##

## Use IPv6?

##

server.use-ipv6 = "disable"

##

## bind to a specific IP

##

#server.bind = "localhost"

##

## Run as a different username/groupname.

## This requires root permissions during startup.

##

server.username  = "lighttpd"

server.groupname = "lighttpd"

##

## enable core files.

##

#server.core-files = "disable"

##

## Document root

##

server.document-root = server_root + "/lighttpd"

##

## The value for the "Server:" response field.

##

## It would be nice to keep it at "lighttpd".

##

#server.tag = "lighttpd"

##

## store a pid file

##

server.pid-file = state_dir + "/lighttpd.pid"

##  Logging Options

## ------------------

##

## all logging options can be overwritten per vhost.

##

## Path to the error log file

##

server.errorlog             = log_root + "/error.log"

##

## If you want to log to syslog you have to unset the

## server.errorlog setting and uncomment the next line.

##

#server.errorlog-use-syslog = "enable"

##

## Access log config

##

include "conf.d/access_log.conf"

##

## The debug options are moved into their own file.

## see conf.d/debug.conf for various options for request debugging.

##

include "conf.d/debug.conf"

##  Tuning/Performance

## --------------------

##

## corresponding documentation:

## http://www.lighttpd.net/documentation/performance.html

##

## set the event-handler (read the performance section in the manual)

##

## possible options on linux are:

##

## select

## poll

## linux-sysepoll

##

## linux-sysepoll is recommended on kernel 2.6.

##

server.event-handler = "linux-sysepoll"

##

## The basic network interface for all platforms at the syscalls read()

## and write(). Every modern OS provides its own syscall to help network

## servers transfer files as fast as possible

##

## linux-sendfile - is recommended for small files.

## writev         - is recommended for sending many large files

##

server.network-backend = "linux-sendfile"

##

## As lighttpd is a single-threaded server, its main resource limit is

## the number of file descriptors, which is set to 1024 by default (on

## most systems).

##

## If you are running a high-traffic site you might want to increase this

## limit by setting server.max-fds.

##

## Changing this setting requires root permissions on startup. see

## server.username/server.groupname.

##

## By default lighttpd would not change the operation system default.

## But setting it to 2048 is a better default for busy servers.

##

server.max-fds = 2048

##

## Stat() call caching.

##

## lighttpd can utilize FAM/Gamin to cache stat call.

##

## possible values are:

## disable, simple or fam.

##

server.stat-cache-engine = "simple"

##

## Fine tuning for the request handling

##

## max-connections == max-fds/2 (maybe /3)

## means the other file handles are used for fastcgi/files

##

server.max-connections = 1024

##

## How many seconds to keep a keep-alive connection open,

## until we consider it idle.

##

## Default: 5

##

#server.max-keep-alive-idle = 5

##

## How many keep-alive requests until closing the connection.

##

## Default: 16

##

#server.max-keep-alive-requests = 16

##

## Maximum size of a request in kilobytes.

## By default it is unlimited (0).

##

## Uploads to your server cant be larger than this value.

##

#server.max-request-size = 0

##

## Time to read from a socket before we consider it idle.

##

## Default: 60

##

#server.max-read-idle = 60

##

## Time to write to a socket before we consider it idle.

##

## Default: 360

##

#server.max-write-idle = 360

##

##  Traffic Shaping

## -----------------

##

## see /usr/share/doc/lighttpd/traffic-shaping.txt

##

## Values are in kilobyte per second.

##

## Keep in mind that a limit below 32kB/s might actually limit the

## traffic to 32kB/s. This is caused by the size of the TCP send

## buffer.

##

## per server:

##

#server.kbytes-per-second = 128

##

## per connection:

##

#connection.kbytes-per-second = 32

##  Filename/File handling

## ------------------------

##

## files to check for if .../ is requested

## index-file.names            = ( "index.php", "index.rb", "index.html",

##                                 "index.htm", "default.htm" )

##

index-file.names += (

"index.xhtml", "index.html", "index.htm", "default.htm", "index.php"

)

##

## deny access the file-extensions

##

## ~    is for backupfiles from vi, emacs, joe, ...

## .inc is often used for code includes which should in general not be part

##      of the document-root

url.access-deny             = ( "~", ".inc" )

##

## disable range requests for pdf files

## workaround for a bug in the Acrobat Reader plugin.

##

$HTTP["url"] =~ "\.pdf$" {

server.range-requests = "disable"

}

##

## url handling modules (rewrite, redirect)

##

#url.rewrite                = ( "^/$"             => "/server-status" )

#url.redirect               = ( "^/wishlist/(.+)" => "http://www.example.com/$1" )

##

## both rewrite/redirect support back reference to regex conditional using %n

##

#$HTTP["host"] =~ "^www\.(.*)" {

#  url.redirect            = ( "^/(.*)" => "http://%1/$1" )

#}

##

## which extensions should not be handle via static-file transfer

##

## .php, .pl, .fcgi are most often handled by mod_fastcgi or mod_cgi

##

static-file.exclude-extensions = ( ".php", ".pl", ".fcgi", ".scgi" )

##

## error-handler for status 404

##

#server.error-handler-404   = "/error-handler.html"

#server.error-handler-404   = "/error-handler.php"

##

## Format: <errorfile-prefix><status-code>.html

## Should lighttpd follow symlinks?

##

##

## force all filenames to be lowercase?

##

#server.force-lowercase-filenames = "disable"

##

## defaults to /var/tmp as we assume it is a local harddisk

##

server.upload-dirs = ( "/var/tmp" )

##

##  SSL Support

## -------------

##

## To enable SSL for the whole server you have to provide a valid

## certificate and have to enable the SSL engine.::

##

##   ssl.engine = "enable"

##   ssl.pemfile = "/path/to/server.pem"

##

## The HTTPS protocol does not allow you to use name-based virtual

## hosting with SSL. If you want to run multiple SSL servers with

## one lighttpd instance you must use IP-based virtual hosting: ::

##

##   $SERVER["socket"] == "10.0.0.1:443" {

##     ssl.engine                  = "enable"

##     ssl.pemfile                 = "/etc/ssl/private/www.example.com.pem"

##     server.name                 = "www.example.com"

##

##     server.document-root        = "/srv/www/vhosts/example.com/www/"

##   }

##

## If you have a .crt and a .key file, cat them together into a

## single PEM file:

## $ cat /etc/ssl/private/lighttpd.key /etc/ssl/certs/lighttpd.crt \

##   > /etc/ssl/private/lighttpd.pem

##

#ssl.pemfile = "/etc/ssl/private/lighttpd.pem"

##

## optionally pass the CA certificate here.

##

##

#ssl.ca-file = ""

ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2)

1、看mysql服务是否在运行：

　　由于“socket”文件是由mysql服务运行时创建的，如果提示“ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘***‘ (2)”，找不到“socket”文件，我们首先要确认的是mysql服务是否正在运行。

四、故障解决方法：

解决方案一：

　　修改“/etc/my.cnf”配置文件，在配置文件中添加“[client]”选项和“[mysql]”选项，并使用这两个选项下的“socket”参数值，与“[mysqld]”选项下的“socket”参数值，指向的socket文件路径完全一致。如下：

修改完后，重启mysqld服务，即可解决此问题。
　

2、确定“socket”文件正确位置：

　　确定mysql服务正常运行后，产生此错误的原因只剩下“socket”文件路径不正确了，我们可以使用“find”命令或者“lsof”命令来确定socket文件的正确路径：

解决方案二：

　　使用“ln -s /storage/db/mysql/mysql.sock /var/lib/mysql/mysql.sock”命令，将正确的socket文件位置，软链接到提示错误的socket文件路径位置，即可解决此问题：
