centos7mongoDB启动与停止、环境搭建
一、环境搭建
Step 1: 禁用 SELINUX=disabled
[root@k8s-master conf]# vi /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
# SELINUX=disabled
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
Step 2: 下载安装文件
下载地址: https://www.mongodb.org/downloads.
或者直接在命令提示符下使用curl命令下载
curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.0.6.tgz
Step 3: 解压下载的文件
# pwd
/usr/local/src
# tar -xvf mongodb-linux-x86_64-rhel62-3.0.6.gz ###注,本文直接从网站下载,所以文件为.gz
Step 4: 复制解压文件到运行目录
# mkdir -p /var/lib/mongodb
# cp -R -n /usr/local/src/mongodb-linux-x86_64-rhel62-3.0.6/. /var/lib/mongodb/
Step 5: 设置环境变量
# vi /etc/profile
export PATH=/var/lib/mongodb/bin:$PATH
# source /etc/profile
Step 6: 创建数据目录
# mkdir -p /data/mongodata
# mkdir -pv /data/mongodata/{rs1,rs2,rs3}
# mkdir -pv /var/lib/mongodb/conf
二,启动方式
1、基于命令行方式启动mongodb
# mongod --dbpath=/data/mongodata/rs1 --logpath=/data/mongodata/rs1/rs1.log &
缺省端口为
[root@node3 rs1]# netstat -nltp|grep mongod
tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 5062/mongod
2、基于配置文件的命令行启动
vi /var/lib/mongodb/conf/rs2.conf
port = 27000
dbpath = /data/mongodata/rs2
logpath = /data/mongodata/rs2/rs2.log
smallfiles = true
fork = true
pidfilepath = /var/run/mongo.pid
# mongod --config /var/lib/mongodb/conf/rs2.conf &
# netstat -nltp|grep 27000
tcp 0 0 0.0.0.0:27000 0.0.0.0:* LISTEN 5356/mongod
3、以守护进程方式启动mongodb
# mongod --dbpath=/data/mongodata/rs3 --logpath=/data/mongodata/rs1/rs3.log --fork --port 28000
# netstat -nltp|grep mongod
tcp 0 0 0.0.0.0:28000 0.0.0.0:* LISTEN 5465/mongod
tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 5435/mongod
tcp 0 0 0.0.0.0:27000 0.0.0.0:* LISTEN 5448/mongod
4、使用系统服务的方式启动mogodb
4.1 新建配置文件
#cd /var/lib/mongodb/conf
# vi mongodb.conf
port = 27017
dbpath = /data/mongodata/rs1
logpath = /data/mongodata/rs1/rs1.log
smallfiles = true
fork = true
pidfilepath = /var/run/mongo.pid
4.2 新建脚本
#vi /etc/init.d/mongod
#!/bin/sh # chkconfig: #MogoDB home directory MONGODB_HOME=/var/lib/mongodb #mongodb command MONGODB_BIN=$MONGODB_HOME/bin/mongod #mongodb config file MONGODB_CONF=$MONGODB_HOME/conf/mongodb.conf #mongodb PID MONGODB_PID=/var/run/mongo.pid #set open file limit SYSTEM_MAXFD=65535 MONGODB_NAME="mongodb" . /etc/rc.d/init.d/functions if [ ! -f $MONGODB_BIN ] then echo "$MONGODB_NAME startup: $MONGODB_BIN not exists! " exit fi start(){ ulimit -HSn $SYSTEM_MAXFD $MONGODB_BIN --config="$MONGODB_CONF" --fork ##added ret=$? if [ $ret -eq 0 ]; then action $"Starting $MONGODB_NAME: " /bin/true else action $"Starting $MONGODB_NAME: " /bin/false fi } stop(){ PID=$(ps aux |grep "$MONGODB_NAME" |grep "$MONGODB_CONF" |grep -v grep |wc -l) if [[ $PID -eq 0 ]];then action $"Stopping $MONGODB_NAME: " /bin/false exit fi kill -HUP `cat $MONGODB_PID` ret=$? if [ $ret -eq 0 ]; then action $"Stopping $MONGODB_NAME: " /bin/true rm -f $MONGODB_PID else action $"Stopping $MONGODB_NAME: " /bin/false fi } restart() { stop sleep 2 start } case "$1" in start) start ;; stop) stop ;; status) status $prog ;; restart) restart ;; *) echo $"Usage: $0 {start|stop|status|restart}" esac
[root@k8s-master conf]# service mongod start
Starting mongod (via systemctl): [ OK ]
三、停止
service mongod stop
