centos7最小版本安装nginx+tomcat+java+mysql运行环境

　　最近项目从windows搬到linux，由于项目组成员有限并且有其它紧急的任务需要处理，因而这个任务就落到我的头上了。下面记录下centos最小版本安装nginx+tomcat+mysql+java的运行环境。

centos7 minimal安装

　　参考：http://www.tecmint.com/centos-7-installation/

安装java

　　下载Java，可到oracle官网获取相应的连接

wget http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.tar.gz?AuthParam=1456375809_50db5985ac01ede6091b467add0b89b2

# 改名：
mv jdk-7u79-linux-x64.tar.gz?AuthParam=1456375809_50db5985ac01ede6091b467add0b89b2 jdk-7u79-linux-x64.tar.gz
# 解压： 
tar -zxvf jdk-7u79-linux-x64.tar.gz
# 更换目录：
mv ./jdk1.7.0_79 /usr/local/ jdk1.7.0_79

　　添加到环境变量

root@localhost java]# vi /etc/profile
# 在export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL下添加
export JAVA_HOME=/usr/local/jdk1.7.0_79

export PATH=$JAVA_HOME/bin:$PATH

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

　　执行

source /etc/profile

　　使环境变量生效

　　查看是否安装成功

[root@localhost jdk1.7.0_79]# java -version
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

安装tomcat

# 创建用户
groupadd tomcat
useradd -s /bin/bash -g tomcat tomcat
下载：
wget http://apache.opencas.org/tomcat/tomcat-7/v7.0.68/bin/apache-tomcat-7.0.68.tar.gz

# 解压：

tar -zxvf apache-tomcat-7.0.68.tar.gz
复制：
cp -R ./apache-tomcat-7.0.68 /usr/local

cd /usr/local/apache-tomcat-7.0.68
修改权限：
chown -R tomcat:tomcat apache-tomcat-7.0.68
启动：
sh ./bin/startup.sh

　　将8080端口添加到防火墙例外并重启

firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --reload

　　访问：http://IP:8080/，熟悉的感觉

安装Mysql

# 创建用户
groupadd mysql
useradd -g mysql -s /sbin/nologin -d /dev/null mysql
# 查看mysql用户
id mysql
# 下载：
wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz
tar -zxvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz
mv mysql-5.7.11-linux-glibc2.5-x86_64 /usr/local/mysql
chown -R mysql:mysql mysql
cd /usr/local/mysql
mkdir /data
cd /data
mkdir mysql
cd mysql
mkdir -p mysql3306/{logs,tmp,data}
cp /usr/local/mysql/support-files/my-default.cnf /data/mysql/mysql3306/my.cnf
vi /data/mysql/mysql3306/my.cnf
修改
# 指定data目录
datadir=/data/mysql/mysql3306/data/
指定监听端口
port=3306
# 表名忽略大小写
lower_case_table_names=1

　　初始化mysql，（注意获取初始化密码），命令安装也可参考：centos7 安装mysql5.7.11注意事项

[root@localhost mysql]# bin/mysqld --defaults-file=/data/mysql/mysql3306/my.cnf --initialize
2016-02-26T10:28:43.821897Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

# 此处需要注意root用户生成的随机密码，后面要用到。

　　启动mysql

 bin/mysqld --defaults-file=/data/mysql/mysql3306/my.cnf --user=root

　　设置root用户密码

[root@localhost mysql]# ./bin/mysqladmin -uroot -p password
Enter password: 
New password: 
Confirm new password: 
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.

　　编辑/etc/profile，将mysql添加到环境变量（可参考java添加环境变量的方法）

export PATH=$PATH:/usr/local/mysql/bin/

安装nginx

　　安装依赖库

yum -y install gcc-c++
yum -y install pcre pcre-devel
yum -y install zlib zlib-devel
yum -y install openssl openssl-devel libssl-dev

　　下载并解压

wget http://nginx.org/download/nginx-1.9.12.tar.gz
tar -zxvf nginx-1.9.12.tar.gz

　　编译安装

./configure --sbin-path=/usr/local/nginx/nginx --conf-path=/usr/local/nginx/nginx.conf --pid-path=/usr/local/nginx/nginx.pid --with-http_ssl_module
make
make install

　　如果没报错的话，查看是否安装成功

whereis nginx

　　添加到防火墙例外

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload

　　启动nginx

/usr/local/nginx/nginx

　　访问：http://IP/，熟悉的味道

    }

}

　　检测配置文件

/usr/local/nginx/nginx -t
nginx: the configuration file /usr/local/nginx/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/nginx.conf test is successful

　　平滑重启nginx

/usr/local/nginx/nginx -s reload

　　/home/www/web/ROOT目录下创建test.html内容为“nginx static html”

　　访问：http://IP/test.html

　　此时访问的是nginx静态资源所在的目录

　　http://IP/index.jsp

　　此时html等静态文件访问的是nginx指定的静态文件目录，而jsp文件则分发到tomcat进行处理。

服务自启动

　　mysql自启动

1./usr/lib/systemd/system目录下新建mysql.service
    [Unit]
Description=mysql
After=syslog.target network.target remote-fs.target nss-lookup.target
[Service]

Type=forking
LimitNOFILE=max_open_files
PIDFile=/usr/local/mysql/mysql.pid

TimeoutSec=0

PermissionsStartOnly=true

ExecStartPre=/usr/local/mysql/

ExecStart=/usr/local/mysql/bin/mysqld --defaults-file=/data/mysql/mysql3306/my.cnf --user=mysql

ExecReload=/bin/kill -s HUP $MAINPID

ExecStop=/bin/kill -s QUIT $MAINPID

PrivateTmp=false
Nice=nice_level
LimitCore=core_file_limit
Environment="LD_PRELOAD=/usr/local/mysql/lib"
Restart=on-failure

RestartPreventExitStatus=1
[Install]

WantedBy=multi-user.target

　　允许mysql开机启动

systemctl enable mysql

　　检查配置是否成功

systemctl is-enabled mysql

　　mysql开启慢查询

/data/mysql/mysql3306/my.cnf中添加
# 慢日志
slow_query_log=1
slow_query_log_file=/data/mysql/mysql3306/logs/localhost-slow.log
slow_launch_time=1

　　nginx和tomcat自启动（和mysql类似，不再阐述）
